Smart Tier 3 engine-powered forklift trucks

Piston pump for oil and fluid grease lubrication SKF has announced the introduction of the pneumatically driven PPS30 piston pump for small- to medium-sized oil and fluid grease lubrication applications. Featuring a compact, modern industrial design, this affordable pump is constructed from lightweight, high-perfor- mance plastics. The PPS30 piston pump is simple to install and provides a flexible connection system for convenient mounting. Because it is pneu- matically driven, the PPS30 is not limited by international voltage or plug standards and can reduce pump inventory needs, because no separate stock keeping of oil and fluid grease is necessary. In addition, the piston pump reduces operating costs over the unit’s life cycle through minimal compressed air consumption. The pump unit features an integrated relief valve and electronic sensors, as well as visual fill-level monitoring that is supplemented by an electronic pre-warning function. Simple to clean, the PPS30 piston pump has a central reservoir opening that fills from all sides and a forward- opening flap for drip protection. www.skf.com

Floor grating products from Andrew Mentis set the benchmark in South Africa, according to Elaine van Rooyen, marketing manager at Andrew Mentis. These highly engineered products have been used by local and international companies for more than 40 years. They are manufactured in a world-class facility at Elandsfontein, Johannesburg, to ISO 9001:2008 standards, using a pressure locking system pioneered by the company. The two main floor grating products from Andrew Mentis are Rectagrid RS40 and Gripweld. RS40 is a premium brand produced by means of compressive pres- sure locking of bearer bars and transver- sals to form a pitch of 40 mm by 40 mm. Gripweld on the other hand features transverse bars fusion welded into the bearer bars. RS40’s non-slip characteris- tics are due to the positive raised sections that create multi-directional obstructions on the top of each bearer bar, allowing for a far larger surface contact area. Non-slip grating and serrated grating products from Andrew Mentis are promi- nent in industries from petrochemical to Smart internal combustion engine forklift trucks, which have a power-shift transmission and loading capacities of 2.0, 2.5 and 3.0 t, are now available with two new types of engines – Isuzu C240 diesel engines and GCT K21 gasoline engines. The new Isuzu C240 engines have a rated output of 35.4 kW at 2 500 rpm, a maximum rated torque of 140 Nm at 1 800 rpm and a service weight of 4 240 kg, while the new GCT K21 gasoline engines are rated at 34.6 kW at 2 250 rpm with a maximum rated torque of 153 Nm at 1 800 rpm. Isuzu C240 engines meet Tier 3 Floor grating: SA’s benchmark “Smart engine-powered counter-balanced type forklift trucks are now available with two new types of engines to enhance existing Kubuto diesel engines. A wider choice of gasoline or diesel engines pro- vides the flexibility to meet the diversified performance requirements of industrial trucks,” says Brenton Kemp, managing director, Criterion Equipment, a wholly owned subsidiary of Invicta Holdings. “Al- though there are no significant changes in specifications or external appearance of this series, the engine changes will improve performance,” he adds.

Criterion Equipment has launched a new range of Smart TCM engine-powered forklift trucks with engine management systems that deliver efficient power, economic operation and enhanced reliability. emission control regulations and have an engine management system that deliv- ers efficient power, economic operation and enhanced reliability. These Smart machines have a full hydraulic steering system without knob shift control. All the operator has to do is keep turning the hand-wheel at the end of each position. TCM forklifts, reach trucks and container handlers are available from Criterion Equipment branches, as well as dealers and agencies. The company provides a technical advisory and support service throughout Southern Africa. www.criterion.co.za

Relative humidity and temperature transmitter for HVAC industry

mining, where stringent safety require- ments are critical in product selection. Grating is available in mild steel, gal- vanised, 3CR12 and stainless steel for a variety of applications and environmental challenges. “Andrew Mentis has also developed a range of corrosion-resistant floor grating ideally suited to the extreme conditions found in wastewater treatment plants. All products in this range are designed and engineered to suit situations where the strength to weight ratio is important, such as wastewater treatment plants,” van Rooyen says. www.mentis.co.za Non-slip grating and serrated grating products from Andrew Mentis are ideal for applications involving stringent safety requirements.

Michell Instruments, represented in South Africa by Instrotech, a Comtest Group company, is offering their WM Series, a wall-mount relative humidity (RH) and temperature multi-unit transmitter. The unit has the ability to display and provide an output signal of relative humidity (%), dew point or absolute humidity and temperature. Analogue output options include 4.0 to 20 mA, zero to 10 Vdc, zero to 5.0 Vdc and zero to 1.0 Vdc. The 4.0 to 20 mA version is loop powered while the voltage output versions are pow- ered by a 14 to 30  V dc supply. The WM Series offers excellent measurement accuracy and stability (+1 % for RH over 12 months) wherever a wall-mounted sensor is required. The WM Series finds application in HVAC and building management systems, swimming pools, pharmaceutical storage facilities and climate room monitoring. www.instrotech.co.za
