Bay, Bloemfontein, Mthatha, Cape Town, East London, Port Elizabeth and George. To guarantee seamless operations throughout Africa, Kemach JCB’s network of distributors and service dealers are also strategically positioned inWindhoek, Nelspruit, Swaziland, Polokwane, Upington, Schweizer Reneke, andVryheid. “We get good support from JCB itself with a local team based here to support us. We have direct contract with our fac- tories so there is support from the OEM itself,” Senyard confirms. “I must say that I have visited the fac- tories in the UK and in India, and have been blown away by the high-tech facil- ities. Whether in India or anywhere in the world for that matter, it is the same level of professionalism throughout. “Our customers are seeing the value in the product, they are seeing the value in resale and it is our customers who are putting us ahead of everybody else,” Senyard says, adding that the involve- ment of senior management is tremen- dous. “Our CEO Les Lothian attends events and product launches, locally and internationally, and is very much involved in meetings and discussions with our cus- tomers. From a customer point of view this is invaluable.” In conclusion, Senyard says that although the company doesn’t have mining equipment as such, there is a lot of support equipment that goes into the mines. “The JS305 and 455 machines are ideal for the quarrying environ- ment, “typically for aggregates loading, stockpiling, feeding the bins, etc. I see a great opportunity for aggregates han- dling with these products. Our dealer in Sweizer Reneke has moved of couple of the 455ZXs to the diamond diggers and again, the fuel consumption figures have been tremendous.” The company offers the best in earth- moving equipment, ranging from the backhoe loaders to skid steers, wheel loaders, excavators, telescopic handlers, rough terrain forklifts, and compaction equipment. In addition to the equip- ment itself, Kemach JCB distributes the full range of JCB parts, while skilled field service technicians and expert product support engineers ensure that assistance is available at all times on a 24/7 basis. www.kemachjcb.co.za

health details, service requirements, operating information, etc. • Optional three-spool hydraulics enables various attachments to be used for extra machine versatility. • Air conditioning comes as standard. • Internal noise in the cab measures a mere 74 dBA. • Useful storage behind the rear seat, keeping the forward operating area uncluttered and safe. Maintenance is simple, with access to the engine bay and cooling pack achieved with wide-opening gullwing doors. Daily checks and grease points are accessible from ground level; while the cooling pack is a single-faced unit, allowing excellent access for cleaning. “The new JCB 455ZX is designed to move more material for less and to this end, we’ve built the engine, axles, drive- line and hydraulics to work in harmony with each other,” he says, “with safety being a priority.” The 455ZX’s cab is isolated from the chassis by rubber mounts, which keeps noise and vibration levels to a minimum. It is also compliant with ROPS/FOPS stan- dards, and positively pressurised against dust. “This purpose-designed unit is built to cope with demanding environments,” Senyard says. “We have units in the coun- try and have quite a few sold already. The results we’ve had from the demos and the machines that are working, especially in terms of fuel consumption have been impressive. “In two different applications where the customer has run competitive machines, we’ve had a 20-30% better fuel consumption figure. When one looks at those numbers, this is a R30-50/hour sav- ing on fuel.” As with the JC305 excavator, the inno- vative LiveLink software permits remote management of the machine either online, by email or by mobile phone. Access from everything from machine alerts to fuel reports and history informa- tion, is stored at a secure centre. Discussing service, Senyard says this is ensured through the company’s extensive African footprint, including its national office based in Gauteng, and regional offices situated in Johannesburg, Pretoria, Middelburg, Durban, Richards

large particles as well as increasing capacity for filter life. “The new JCB is highly productive,” Senyard says. Its engine offers high power and torque, while its hydraulics and loader end are set up to keep cycle times short and working shifts long.” A state-of-the-art engine manage- ment system offers optimised perfor- mance and fuel efficiency. The Dieselmax 672 engine offers the latest generation EcoMax lean-burn combustion system. The six-cylinder 7,2 ℓ engine achieves higher power (165 kW) and peak torque (1 000 Nm) at low revs. “There is a 310 ℓ fuel tank as standard on the 455ZX, along with extremely effi- cient matching of hydraulics,”he says. “This combination ensures maximum uptime between refuelling; a welcome feature when you’re working in remote areas where diesel has to be transported in.” Discussing loading productivity, he says the Z-bar loading geometry is capable of exceptional productivity, due to com- prehensive penetration into the pile, high breakout forces, good roll-back angles and faster dig times.“There is an added benefit from reduced tyre wear and superior fuel efficiency, making this machine a good investment for any business.” The innovative electronic manage- ment system controls tractive effort via the transmission; diverting maximum power to the loader hydraulics and reducing service brake wear and fuel consumption. The 455ZX is fitted as standard with limited slip differentials that are perfect for soft, muddy terrain with reduced trac- tion. Its selectable loader arm detents enable operators to set loader arm height limitations, return to dig and float func- tion for improved safety and productivity. “Keeping operators fresh and alert all day long results in increased safety and productivity,” Senyard confirms. “The 3,0 m 3 cab is roomy, easy to access and quiet. It also has excellent visibility and an intuitive, ergonomic control layout.” Other features include: • The 455ZX is fitted with an easily adjustable tilting and telescopic steer- ing column. • A stylish, modern central dash display combines analogue dials and a colour LCD screen – this can display machine
