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
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
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.
