JCB Construction Equipment, solely represented in South Africa by Kemach Equipment (Pty) Ltd (Kemach JCB) is in the process of launching two formidable machines to market; these being the JS305 LC tracked excavator and the 455ZX wheeled loading shovel. Dale Kelly visits national support and marketing manager Mark Senyard at the Jet Park head office, to talk about these rugged workhorses. Making things easy

fuel quality and an engine and hydrau- lics designed with productivity in mind,” Senyard says. At its heart is a formidable 7,2 ℓ Dieselmax engine that produces huge amounts of power and torque. Key fea- tures include: • The six-cylinder engine produces its peak power (165 kW) and torque (960 Nm) at a low1 300 rpm. This allows fuel-efficient matching of the engine and hydraulics. • With a massive 222,6 Nm of bucket tearout, fast cycle times are assured in all applications. The intuitive multi- function operation makes simultane- ous tracking and excavating smooth and fast. • The JCB JS305 provides a solid, stable work platform for fast cycle times. Senyard says the control valve optimises hydraulic oil supply to different functions during combined operation. This multi- function prowess guarantees fast cycle times. “When you’re tackling tough applica- tions and difficult working conditions, one needs a durable and reliable machine. The JS305 offers exactly that with high-qual- ity components along with simple and robust mechanical fuel injection. The Dieselmax engine has a mechan- ical in-line Bosch fuel injection system which allows work in areas where fuel quality is poor. The machine benefits from a multi-stage fuel filtration system which protects against a wide range of contam- inants as small as two microns. “We use high tensile strength steel to construct the reinforced boom and dipper and internal battle plates help to ensure long-life durability, as do the heavy-duty wear strips at the dipper end,” he tells MQ adding that the advanced manufacturing and assembly processes help to guaran- tee an extremely high level of precision and quality in the components. “The JS305 is built to last. With a heavy-duty lower frame and upper

E stablished in 2003, Kemach J CB i s a j o i n t ven t u r e between the shareholders of BH Botswana and Muscat Overseas in Oman. Both these companies are the sole JCB dealers in their respective countries. As a leading earthmoving solutions dealer, Kemach JCB supplies high-calibre equipment to the mining, construction, quarrying and plant hire industries, as well as the central government. A focused dealer of distinguished equipment and support, Kemach JCB continuously strives to put the customer at the heart of its business, fixated on meeting each client’s unique needs. Senyard says that both machines have been manufactured at JCB’s state-of-the- art facility in India and are designed to be easy to operate, easy to maintain and to move more material at less cost.

Referring to the JS305, Senyard says the first two units have arrived with another two on the way. “Further orders have been placed for additional machines to ensure our order pipeline is in place to fulfil what we believe will be an increased demand for this machine. The JS305 has been on test in India and in South Africa, where it is on trial by a customer. “The feedback we’ve had both from India and here in South Africa has been excellent particularly in terms of fuel con- sumption. The unit slots in with the JS205 that JCB launched many years ago.” The JS305’s Dieselmax engine is built for the African and Middle East market as well as for lesser-regulated countries. “It’s not a Tier 4 engine and is ideal especially in terms of fuel consumption, and that goes for the 455 as well. “The 305 has a simple mechanical fuel injection system that tolerates lower
