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
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
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.
