NEW ELECTRICAL CONCEPT STORE OPENS IN GAUTENG

V oltex, South Africa’s largest wholesaler and distributor of electrical and lighting related products, has embarked upon a drive to rebrand and, where necessary, relocate branches with the aim of improving existing customer relationships and draw ing in new customers with a fresh and innovative shopping experi ence. Voltex Alberton is the first of its new concept stores in the Gaut eng area. Customers will be exposed to a hands-on experience of state-of-the-art products assisted by the trained and qualified sales staff. The product range has been carefully selected, particu larly in the energy efficiency and lighting markets. These areas are of particular focus right now as the world moves towards greener solutions. Of special interest is a live solar display where custom ers can see exactly how a system works, as well as a small lighting showroom showing off the latest trends. Voltex still remains invested in its current range of electrical and related products. Practically, our new concept store is everything you would expect from a Voltex store, but with a little extra. Lizel de Jager, National Marketing at Voltex explains that when the store moved from its original premises in Alberton North, just 3 km away, the company used the opportunity to launch the new concept. The new location, at the Alberton Lifestyle Centre, 57 Saint Austell Street, New Redruth, is close to the highway offramp and, being in a strip mall, will ensure higher foot traffic. With its retail setup, the store has a different look and feel, cater ing for both domestic and contractor’s needs, while still offering the ability to supply for specialised projects. Special attention was given to the displays, ensuring that prod ucts are presented in a way which is helpful to DIY enthusiasts or homeowners who may not be familiar with electrical products. Having expert staff on hand to help, currently five employees who have all move across from the old store, is a lot less daunting for customers than shopping at a trade counter. The store was launched on 9th May where the Group also took the opportunity to introduce this new concept of Voltex to its sup pliers. “One of the key things for us is our supplier contact, explains de Jager, “Making sure that our suppliers know about what we are doing here and how best to present their products.” Voltex also of fers its suppliers branding boards inside the store to display their

latest products. Numerous suppliers joined Voltex at the opening to enjoy pizza, watch the ribbon cutting and display their products to visitors and customers.

The state of smart home adoption in SA

S outh Africa lags behind the world in smart home ownership, with a 23% gap between South African and global consumers when it comes to embracing the use of internet-connected devices to enable the remote monitoring and man agement of appliances and systems. “While there are some understandable barriers to smart home adoption in South Africa, oppor tunities also exist for smart home proliferation,” says Dr Andrew Dickson, Executive: Engineering at CBI-electric: low voltage. He notes that one of the critical hindrances is internet accessibility. According to the latest Digi

tal Quality of Life survey, which ranks countries based on five pillars – internet affordability, in ternet quality, e-infrastructure, e-security, and e government, South Africa placed 68 th out of 110 countries. “While we took the 26 th spot for afford ability, we didn’t perform as well on internet quality where we ranked 57 th and 87 th for electronic infra structure – both of which are essential for effec tive use of smart home technology.” However, he says there is hope. “Earlier this year, the Minister of Communications and Digi tal Technologies, Khumbudzo Ntshavheni, stated that every South African will be given access to

the internet as a core utility. During her State of the Nation debate, she said ‘data has become a new utility, like water and electricity, that our home needs. At some point, a South African household, whether rich or poor, will be given access to 10 GB per month, because that is what the government will deliver’.” Another hurdle Dr Dickson has observed locally and globally is mistrust of smart home tech. Sur veys conducted amongst consumers in Australia, Canada, France, Japan, the UK and the US, have found that many are sceptical about consumer Internet of Things devices, which include smart

home technologies. For example, 63% of peo ple surveyed said they find connected devices ‘creepy’ in the way they collect data about people and their behaviour, while 28% stated they will not own a smart device due to security concerns. “If these are the attitudes of consumers in more developed countries where smart devices are more pervasive and more advanced, one need only imagine the perceptions of the local market. Education around the capabilities and safety elements of these devices is clearly lack ing and will be crucial for putting consumers’ minds at ease and expanding the South African smart home market.” Cost is an additional concern. “The most recent BankservAfrica Take-home Pay Index has re vealed that the average South African real take home salary is R16 022, which makes it all the more difficult for South Africans to adopt smart home technology, especially when it comes to devices from overseas. That said, there are sev eral locally developed products that are available at a more affordable rate. Plus, there are ways to make homes smarter without enormous cash outlays. Homeowners themselves will need to be smart in how they go about doing so, such as by installing one smart device at a time and focus sing on energy intensive appliances or security areas first.” Despite the obstacles, Dickson believes that current market conditions, like the accelerated digital adoption rate, will enable increased smart home device implementation: “Since the COV ID-19 pandemic struck, homes have been turned into digital hubs for work, study and entertain ment. Smart homes are a natural evolution.” He concludes by saying, “As more South Afri cans become aware of the benefits smart home devices offer, such as monitoring and manag ing electricity consumption, as well as providing appliances with some protection in the event of load shedding surges, the adoption rate will in crease in the country. Simply put, smart is the way for homes of the future.”

How to use Facebook to market your trade business

O ver the years, Facebook has become more than just an on line meeting place for family and friends. As one of the big gest social networking sites in the world, it presents many opportunities for businesses to market themselves – and to con nect with existing and new customers. With so many ways to promote your business on Facebook, it can be hard to know where to start. The key is using Facebook’s tools ef fectively to broaden your reach (the amount of people who see your business), engage with potential customers, drive enquiries and get more business. Here’s how to set up a Facebook Business page and make it work for your trade business. Create a Facebook Business Page Creating a Business Page on Facebook is pretty straightforward. To get started you’ll need: • Your own personal profile on Facebook. • Information about your business, e.g., contact and ‘about me’ in formation. To create a Facebook business page: • Open your personal Facebook profile (from your desktop). • Select Create at the top of the homepage and choose Page. • Name your page. • Add a category to describe your page. • Enter business information such as address and contact details. • Select Continue. How to set up a Facebook Business Manager ac count Before you get stuck into the nitty-gritty of using Facebook to mar ket your business, create a Business Manager account. Business Manager keeps your Business Page content separate from your personal Facebook profile. It’s where you can run and track ads, manage your accounts, and coordinate your marketing efforts. To create a Business Manager account: • Go to business.facebook.com/overview. • Click Create Account. • Enter a name for your business, your name and work email ad dress and click Next. • Enter your business details and click Submit. How to optimise your Facebook business page For many trade businesses, a Facebook page can be a great alterna tive to creating a website. It doesn’t involve any initial design, set-up costs, or ongoing hosting fees – it’s a very cost-effective option. Billions of people use Facebook every day. That means there’s a lot of traffic already moving in your direction, without having to think about search engine optimisation (SEO). But that doesn’t mean you’re guaranteed marketing success. Here are a few tricks of the trade to drive growth and get a good return on your investment. Upload a good profile photo: Choose one that clearly shows your business name, colours and brand. It should be instantly recognis able and used across your digital marketing efforts. Add a cover photo: This helps to grab people’s attention. Use a sim ple image with a focal point. Consider adding your business contact details, your tagline, or photos of employees to encourage people to take action on your page. Don’t be afraid of empty space around your words – it will help them stand out. Write a description: Keep it short and sweet. Tell people in one or two sentences what you do. The About and Story sections are where you can add more detail about what areas you service, what makes you different, and testi monials to show your work ethic and credibility. Add a call-to-action button: Create a call-to-action button so leads can send you an enquiry, view your website (if you have one), or call you. Keep contact information up to date: Ensure your contact informa tion is correct and up to date with at least a phone number or email address. Add a link to your website if you have one. Add location hours: If you have a physical location, add your ad dress and business hours. Or, you can add the location areas you service. Select your categories: When you set up your Business Page, you’ll be asked to select a business category. You can select up to two more relevant categories. This will help potential customers dis cover your Page. Ask for ratings and reviews: Enable this feature by navigating to Settings > Templates & Tabs > Add a Tab > Reviews. Move this tab up to the top of the list on the left-hand side of your Page to instantly • Add a profile photo to your page, then select Next. • Add a cover photo to your page, then select Next. • Select Next to go to your new page.

show your credibility to new page visitors. Ask your customers to add a review to your Facebook page by sharing the link when send ing out your invoices. Advanced tips for winning more work Studies show that nearly two out of three people on Facebook visit the page of a local business or event at least once a week. Data also shows that if you respond to customers in under five minutes, you’re 100 times more likely to make contact, and 21 times more likely to win more work. While responding in under five minutes isn’t always doable for electrical contractors, try to respond as quickly as you can. You need to be active on your page to grow your Facebook community. Share and post content regularly: CNN Business reports that on average, active Facebook users check their account at least 14 times a day – that means you need to post new material regularly. But think quality over quantity. Post when you have interesting content to share – progress photos of your latest job or a before-and-after video. Your post is 120% more likely to get engagement if it features a photo – for videos, it’s even more. Get familiar with what format and size of images are best to share on Facebook. If taking photos isn’t your strong suit, you can use free software like Canva to add design polish to your photos. Invite people to follow your business: Share your business with your family and friends and encourage them to share your business with others. Use paid ads to promote your business: With a swath of information on users’ activity & interests, it’s no surprise the amount of money spent by businesses advertising on Facebook increases each year. Facebook makes billions of dollars from ads. Facebook Ads Manager is the name of the tool you will use if you are looking to advertise. Before jumping in, consider things like your target customers age, gender, location and interests. What time they’re likely to be using social media and what Facebook apps they’re likely to be using (Facebook, Instagram or Messenger). Craft an ad that fits your business goals e.g.: Promoting a com pleted job (brand awareness), or something more actionable such as an introductory discount to get people using your service. Don’t have time for the nitty-gritty of Facebook Ads Manager? All Facebook Business pages give their owners the ability to boost (pro mote) a post. Keep an eye out for the “Boost Post” button in corner of your feed. For more details on boosting a post, check out this article. Set up an automatic messenger response: When you’re knee-deep in mud, responding to a Facebook message isn’t exactly a top prior ity for you. That’s where using automatic messenger greetings to manage new enquiries can help. Add a greeting, then ask them for their contact details and tell them when they can expect you to be in touch. Make sure you turn your notifications on so you can see when you’ve been contacted through your Page. Set up appointments: Take things one step further and add Face book Appointments to your Business Page. This will allow your cus tomers to see when you’re available for a chat or a job. You’ll still be able to manually approve requests for appointments. Consider installing a chatbot: Chatbots use AI to have a conver sation; they’re programmed to understand questions and provide answers. They’re a fantastic way to scale your business using Face book Messenger. A recent Nielsen survey found that people think messaging is the second-best way to talk to a business, so it’s a great way to pre-qualify your leads without putting your tools down. Avoid the ‘hard sell’: Facebook isn’t the place for aggressive sales tactics. Instead, focus on joining conversations relevant to your work and trade industry, and becoming part of the community. You can still promote your business – just try and strike the right balance between interesting, helpful, and promotional content. Use Facebook Insights to learn about your customers: This is argu ably Facebook’s most valuable marketing tool. There is so much you can learn about the people who choose to like and interact with your page – actionable insights that you can then use to tailor your posts to better meet their needs and interests. Use Facebook to get started with digital marketing Facebook is one of many online tools that you can use to spread the word about your trade business. It’s the kingpin of social media plat forms, and when used effectively, can attract many new enquiries, grow your trade business, and help you connect with your customers. If you already have a Facebook Business Page, and you’re strug gling to see any value, try implementing some of the optimisation strategies suggested. Sometimes the simplest of changes can make all the difference and help you succeed. Also, analyse the data and information that Facebook collects on your Page and custom ers – it is a powerful tool that will help you spot any gaps in your marketing strategy.

Seen at NAMPO: Electrical companies exhibit to the agricultural industry

Grain SA’s NAMPO Harvest Day is one of the largest agricultural exhibitions under private ownership in the southern hemi sphere and it takes place annually, just outside of the town of Bothaville, in the Free State province of South Africa. Companies from the electrical indus try, including ACDC Dynamics, Pratley and Zest WEG, took the opportunity to showcase their products to this sector at this year's event which was held from 16 20 May. NAMPO enables producers and other role players in the agricultural industry to experience the latest technology and products on offer in the farming industry first-hand and on one terrain. The NAM PO Harvest Day also offers producers the opportunity to obtain knowledge from experts in their various agricultural fields by means of debating and discussion panels. A unique aspect of the NAMPO

Harvest Day is that it is a multifaceted presentation that offers a wide spectrum to the producer.

Smartphones or tablets enable companies to im prove their productivity, and the safety of their em ployees. Modern production facilities constantly exchange data. This flood of data is usually managed by cen tral controls. However, for comprehensive and time ly monitoring of processes, data must be available closer to the process and more directly – preferably in real time and with low latency. Modern, intrinsi cally safe smartphones and tablets can serve as decentralised mini data centres or digital gateways, for example, in combination with professional software, sen sors, beacons or other smart peripheral devices. The accu mulated data can be transferred to the mobile device in real time and evaluated there with the corresponding applications, at any location and any time. This way, companies do not only improve their productivity, but they achieve even more: They significantly raise employee safety – especially in hazardous areas. Providing the right safety level In industries with extensive factory premises or potentially explosive areas, employees frequently work alone, outside the range of hearing and vision of their colleagues. They are ex posed to higher risks in their daily work and depend on quick assistance in the case of an emergency. If no appropriate safe ty precautions are taken, injuries, accidents and consequential damage to people and equipment can easily occur. The com pany must ensure that the accident is detected, and the rescue chain set in motion swiftly. Especially when the injured person is unable to act or no one has noticed the accident. In case of critical hazards, it is therefore mandatory to set up a certified lone-worker protection solution (LWP). Equipped with sophisticated lone worker protection software, enterprise mobility solutions reliably protect their users: Pro grammable 3D motion sensors automatically trigger an alarm in the event of a hazard, report the exact location of the incident and document the entire process for later investigation. A com prehensive lone worker protection system consists of Personal

Alarm Signal Terminals PAST (mobile phone, wireless device), Personal Alarm Signal System PASS (software on server) and connection between the PASS and PAST (telephone or wire less network). For larger scale lone worker protection solutions, it is essential that mobile devices can easily be integrated into cloud server systems. The Pepperl+Fuchs brand ecom offers such solutions. The specialist for industrial communication and explosion protection combines state-of-the-art lone worker protection applications with personal emergency response devices. Industrial enterprises are under constant pressure to increase the operational efficiency and productivity of employees, with out sacrificing safety. ecom´s mobile communication solutions as components of a personal emergency response system also meet highest business requirements: Many tasks can be carried out alone, since another person is no longer neces sary for the reason of safety. Besides the obvious advantage of having a constant means of communication with workers in the field – it also enables them to exchange information and data at any time while moving around a plant or work site.

TES partners can help fill the skills gap for the deployment of independent power producers

A s South Africa gears itself toward the Inde pendent Power Producer (IPP) market, the country is poised for economic growth and socio-economic development. Aside from bringing much needed electrical power generation capacity, these projects will also facilitate job creation, social upliftment, and local industry development. How ever, delivering the skills required for these projects – particularly in the rural areas where the renewable generation plants are being developed – can prove to be a challenge. In addition, there is the need to create long-term, sustainable economic develop ment around projects that are temporary in nature. A Temporary Employment Services (TES) provider can assist on both counts and help to bridge the skills gap to assist with the successful deployment of IPPs. The Renewable Energy Independent Power Produc er Procurement Programme (REIPPPP) introduced designated local content, where 40% of an IPP project spend must be sourced locally. This ruling creates tremendous opportunity for our economy, including a significant positive impact on job crea tion, since the current REIPPPP Bid Window 5 is ex pected to create thousands of jobs, and future bid Opportunities and challenges on the horizon L ittle or no care is taken when domestic, com mercial or industrial miniature circuit break ers, MCBs, are selected for use or replace ment. But there probably should be if the existing brand is not to be retained. Specifications are generally no more than a brand or equivalent, if indeed even specified. Within the South African context, we have rather unusual options, not always readily known beyond the brand, and locally designed and made, to boot! As this topic is based on the technology of these circuit breakers let's make sure we have an under standing of what technology is available as well as potential problems that may be encountered in the use of the various technologies. The problem here, from the outset, is that from the outside you do not actually know what tech nology you have. Having brand knowledge is more useful, of course, but replacing on price alone is hit and miss. Locally this is more likely to be miss, as the hydraulic mechanical is far more rare from a supplier number point of view. There are currently three technologies developed and commercialised in circuit breakers generally but one of these has not progressed to the MCB ranges, mainly for space and cost reasons. The fourth technology is a semiconductor-based stand in the side lines, waiting for a break dependant on technology advancement. Externally, there is really no identification of the technology to the untrained eye and without confir mation from the manufacturer, would require open ing to confirm.

A provider with experience in the energy sector as well as relationships in the communities can help IPPs to navigate and manage the intricacies of the relationships between the community and unions to mitigate any risks and concerns for the IPP. In addition, a TES provider can manage the full recruitment process along with the payroll, human resources, and industrial relations, and provide a pool of skills to draw from at short notice. As one of the current challenges is a skills and experience shortage in the Renewable Energy Sec tor, it is imperative to give job opportunities to those with industry specific certifications and qualifica tions as it provides valuable ‘on the job’ skills train ing and development together with sought after work experience. This approach will not only ensure we grow our existing labour force to meet the de mand for a skilled and experienced workforce for our energy sector, will also help these candidates to maximise future employment opportunities. A reputable TES provider is well positioned to assist in this regard. TES providers are committed to local economic development objectives and will continue to play a vital role in assisting IPPs to meet the local con tent target required by the REIPPPP. Success lies in partnering with a TES provider with a solid under standing of the renewable energy sector, the South

windows will bring further job opportunities. However, it also creates challenges for the IPPs. As renewable energy is still new to South Africa, one of the main challenges we face is a shortage of lo cally available skills. While there are individuals with the necessary certifications and qualifications, they often do not have experience specifically within the energy and renewable energy sectors. Furthermore, when it comes to engaging with ward councillors and community leaders, manag ing these relationships requires dedicated attention and a significant understanding of the South Afri can market and labour force. Contentious issues like wage negotiations can increase the potential risk of strikes or unrest if they are not expertly and successfully managed, which could result in very costly delays. Temporary problems In addition to these challenges is the fact that the construction phase of each site requires certain skills on a temporary or project only basis, which can be quite difficult for an IPP to manage when try ing to source the right talent. This includes civil, me chanical, electrical, and engineering skills, as well as new skills required to work with solar panels and inverters. A reputable TES provider can therefore be hugely beneficial in addressing these challenges. spective and, in pure numbers, is the most prolific. As the name suggests, this makes use of the fact that heat is produced as a byproduct of the current through a conductor. In this case the heat is applied to a bi-metal strip* which flexes over time resulting in the mechanism tripping the current and thus of fering the cable protection**. This technology has been highly honed over the years and costs have thus dropped significantly, but some shortfalls can not be designed out unfortu nately as they are inherently there due to the tech nology itself. Hydraulic Magnetic The second oldest patent stated that the magnetic principal that displays with current flow can also be used for cable protection. The current flows in a coil attracting a metal core in a hydraulic fluid un til it reaches the magnetic polepiece and trips the mechanism, again protecting the cable. This technology does require a degree of fine manufacturing tolerances and costs are higher than the thermal types. Costs have dropped as automa tion equipment has become more able to produce consistent tolerances and also because of the equipment being highly automated. Costs remain higher than thermal types but the technology posi tives mean that they are exclusively used for spe cialised protection as in rail transport and telecoms world-wide. Because temperature has little to no effect, their use in climate extremes can also be highly advantageous. Electronic Magnetic Notwithstanding huge advancements in the elec tronic component field, using, for example, cell

Circuit breakers – defining technology

case of current overload we need to understand why the protection is required. 1: Short circuits: Extremely high current can flow if there is a direct short circuit which may burn off or fuse off the cable unless removed in haste. That is the reason for all technologies to have a Magnetic complement as noted above. 2: Overloads: Depending on the actual overload damage over time is possible especially to the plas tic insulation. An inverse tripping is required in this zone. All tripping curves will display this has been achieved using all of the technologies discussed. Hopefully this brief outline of the technologies will give a summary of why some care should be taken in specifying or replacing MCBs. The subject can be rather complex if going into the details is required. If you intend replacing an installed unit with the same type and from the same manufacturer, you probably cannot go far wrong. However, if replacing with another brand and another model you may un intentionally create a problem for later, if not found earlier. No contractor wants to be recalled to site to deal with any issues; there simply is no economics in this approach.

phones as a base line, no current manufacturer pro duces distribution circuit breakers using this technology. As to why this is the case, bear in mind that since breakers are at 18 mm or 13 mm per module (13 mm being the world’s thinnest actually) raw space is required to help with arc quenching and, of course, costs are still at the extreme in comparison. The electrical current is past through a CT/Toroid and the output sent to an electronic circuit for eval uation. Should there be a need this then trips the mechanical breaker. Great strides are being made in larger MCCB and air circuit breakers (ACBs) with this technology however, the main limitation is still cost based.

Keeping electrical workers out of harm’s way

I t is the foundation of any electrical safety pro gramme: limiting the exposure of workers to the electrical hazards of shock and arc flash. Using test leads and clamps to probe inside a live panel when troubleshooting and performing rou tine maintenance always exposes workers to dan ger. Electrical personal protective equipment (PPE) is a last line of defense and must never be relied upon as the primary method of protecting electri cians and technicians. Safe work practices, includ ing the use of non-contact test tools that do not require electrical workers to place themselves in harm’s way, must first be considered when it comes to electrical safety. Fluke Connect®, introduced in 2014, added a level of efficiency and effective collaboration for mainte nance and troubleshooting, in all kinds of manufac turing, commercial, and retail facilities. Technicians can monitor real time results from more than 20 different Fluke test tools from a smart phone (up to 10 at a time on iPhone and six on Android). This in formation can also be securely shared, in real time, with authorised team members in other locations. In addition, test results and maintenance data can be collected through the Fluke Connect app and stored by asset in secure Fluke Cloud™ storage. That means that troubleshooting and maintenance

The Fluke 902 FC True-rms HVAC Clamp Meter features: • Dual rated – CAT III, 600 /CAT IV, 300 V. • Microamps for testing pilot light sensors. • Resistance up to 60 kilohms. • AC current, ac/dc voltage. • Capacitance and contact temperature .

staff can access that data in the field to compare new measurements to baseline measurements and identify problems more quickly. The end result is that technicians can use Fluke Connect to quickly identify and diagnose problems while securely sharing the related data, when they want and with the specific people they have given permission to view it. Fluke released clamp meters – the Fluke 376 FC True RMS AC/DC Clamp Meter with iFlex and the Fluke 902 FC True-rms HVAC Clamp Meter allow technicians to access tight places and work around large, awkward conductors. They can trans mit measurements to a smartphone or tablet for later, detailed analysis. Those measurements can be uploaded to the cloud. Technicians can combine measurement data from multiple Fluke Connect test tools to create and share reports from the job site via email and collaborate in real time with other colleagues with ShareLive™ video calls or email, in creasing productivity in the field. The 376 and 902 clamp meters also decrease the number of times technicians will need to wear personal protective equipment when working on high voltage/current panels.

The advantage of temperature measure ments with the new infrared camera lies in the large amount of information in an IR picture/IR video and the short reaction time of 1 ms for the output of temperature information of freely se lectable individual pixels. The use of these image sensors allows a large dynamic range for temperature measurement so that the previously necessary use of rela tively many and narrowly defined sub-ranges is no longer required. Intelligent measuring with a pyrometer is now possible thanks to the two dimensional temperature recording of the Op tris PI 1M. With the large measurement temperature range of 450-1800 °C, that the Optris PI 1M IR camera offers, it satisfies practically all demands in the fields of metal production and processing. Pertinent features of the Optris PI 1M IR cam era: • Highly flexible CMOS detector with an opti cal resolution of up to 764 x 480 pixels. • Very large temperature measurement range (without sub-ranges) of 450 °C to 1800 °C. • Frame rates of up to 1 kHz for fast processes. • Real-time output of middle pixel at a set-up time of 1 ms. • Includes license-free analysis software and full SDK.

requirements. The integrated DOCU module, with a reliable counting mode for life and maintenance cy cles, enables the accurate recording of over 10 000 bolt connections. The data is transferred via USB interface for archiving completed bolting work. This module and software allow pre-defining of different bolting operations and are available as optional fea tures for certain models. For even more precise tightening of bolts, the LDA Solution offers the torque-angle function. After a tight torque has been reached, the bolt is retightened by the previously determined further angle of rota tion, to guarantee a perfectly defined bolt connection. BMG’s fasteners, tools and equipment portfolio encompasses hand and power tools, cutting and drilling tools, lifting and rigging equipment, hydraulic tools and abrasives, as well as workshop and weld ing equipment and locks and lock-out systems. The division also supplies and supports a full range of fasteners and fastening components. BMG’s Fasteners, Tools & Equipment team works closely with customers throughout Africa to source quality branded products that meet exact require ments. The team’s commitment to customers is to assist in optimising inventory investment and reduce production and maintenance costs, at the same time minimising downtime in every operation.

high-performance aluminium, offer a continuously adjustable torque range from 90 to 13 000 Nm. These tools are equipped with double patented screwdriving control and powerful 90 Watt-Hour Lithium-Ion batteries, that operate at constant peak performance until they are completely discharged. The optional torque rotation angle offers users even higher torque precision and ensures perfectly de fined bolted connections that comply with stringent quality standards. “A sunlight-readable, intuitively operated digital colour display visually represents the entire work process. Other advanced features include a high performance gearbox, low maintenance brushless technology and microprocessor-controlled switch off electronics. For greater safety, there is an auto matic switch-off when the correct torque is achieved. The wrench slacken-function (auto release) is auto matically activated as soon as torque is applied, to allow safe and easy removal of the tool after the re quired torque has been achieved. “These tools have been designed for operator comfort and safe handling. The ergonomic grip is non-slip and fatigue-free, while the 360° rotating drive unit prevents injuries and allows the operator to work in confined spaces.” The LDA Solution is equipped with process-reli able documentation software that ensures quality operation and assists with service and recalibration

BMG’s Fasteners, Tools & Equipment division has ex tended its range of wrenches to include a new genera tion of cordless torque wrenches from Gedore Torque Solutions, with optional process reliable documenta tion software and advanced features for higher torque, greater precision and improved safety. “Our new Gedore LDA/LAW Solution series for bolted connections – which ensures the highest quality and safety standards – is critical in many applications, particularly where bolting connections need to be precise and where bolting procedures must be documented for safety or maintenance requirements,” says Jeremy Pieters, Business Unit Manager – Fasteners, Tools & Equipment Division, BMG. “Typical applications in mining are for open cast and above-ground pipe assemblies, conveyor idlers and specific bolting requirements in materi als handling. These high-precision cordless torque wrenches are well suited for vibrator screens in mills and all motors in different plants. They are designed for safe and efficient operation in earthmoving and construction equipment, wind turbines, vehicle chas sis and specific bolting applications in the automo tive sector. These tools are widely used in the con struction industry for pipeline assembly and all plant environments that are not spark-free. “BMG’s new lightweight LDA Solution (straight version) and LAW Solution (angled version) cord less torque wrenches, which are manufactured from

Makita's recipro saws for cutting wood, metal and piping

Makita’s continuous innovative approach is evident in the two 18 V Lithium-Ion cordless recipro saws, the DJR186ZK and DJR187ZK. Also known as a sabre saw, the recipro saw is basi cally a saw that uses a push and pull motion of the blade to cut into wood, metal and piping. It can be used in the oddest of places and on almost any type of object. Both the DJR186ZK and the DJR187ZK have extra high cutting efficiency and a cutting capacity in mild steel pipe of 130 mm and 255 mm in wood and are ideal for single-handed use. The length of stroke is 32 mm and the DJR186ZK produces a variable speed of 0-2800 strokes per min, while the DJR187ZK’s speed is slightly higher at 0-3000 strokes per min. The DJR186ZK has a tool-less quick and easy blade change and has a comfortable anti-slip soft grip that provides for accurate control and a lock switch at thumb level. The newly designed vertical crank mechanism of both models provides for high er cutting efficiency. The DJR187ZK has an adjust able front shoe which maximises blade usage and a brushless DC motor as well as a LED job light, lock off lever and retractable joist hook. Both models are compatible with the Makita 5.0 Ah (45 minutes charge time), 4.0 Ah (36 minutes charge time), 3.0 Ah (22 minutes charge time) and 1.5 Ah (15 minutes charge time) batteries. The batteries and the charger are sold separately. The rechargeable and eco-friendly 18V Li-Ion batter ies provide longer run time. The LXT Li-Ion battery generates an impressive 430% more lifetime work with two-and-a-half times more cycles.
