axle before returning to the oil reservoir via the
return filter.
Using sensors, audible and visual warnings
will occur in the event of low brake pressure,
or if a fault is present in the brake system.
Hydraulic system
A single or tandem (depending on truck
variant) variable displacement, load sensing
work hydraulic pump is mounted directly to
the transmission. The back pump feeds both
steering and work hydraulic functions while
the front pump (if fitted) feeds the work hy-
draulic system. These pumps are fitted with
pressure compensators which act as safety
valves so that in the event of higher than
expected pressure flow is reduced to zero
and the maximum pressure is maintained at
310 bar.
An externally mounted in-line priority valve en-
sures the steering function has priority over
work hydraulic functions.
The main hydraulic valve is a group of ad-
vanced CANbus controlled, load-independent
proportional valves and include primary and
secondary relief valves that prevent overload
of the hydraulic circuits.
To improve and enhance the safe design of
the hydraulic system the control valves are
fitted with LVDT spool position feedback sen-
sors which enable the valves to monitor their
own condition and broadcast any errors over
the CANbus.
The mast lift/lower section incorporate “leak
free” valves to eliminate the possibility of mast
creep when carrying heavy loads.
A combination cooler ensures that the temper-
atures are kept optimum for the transmission,
engine water and charge air. The cooling di-
rection and cooler location have been careful-
ly developed with the aim of minimising the
size of the cooling pack and maintaining best
in class cooling performance. The cooled air
direction pulls ambient clean air from above
the rear of the truck and drives warm air down
through the engine bay over the engine and
finally out at the front.
Lift mast
The standard mast is a double open centre
non-free lift type with twin lift and tilt cylinders,
lift chains mounted on each side and are at-
tached to the carriage.
Lift movement is achieved when the lift cyl-
inders extend and the lift chains pull on the
carriage, during this extension the inner mast
section slides inside channels of the outer
section.
The whole mast and carriage assembly is
mounted and pivots on two pins that are fixed
and located within the fabrications of the drive
axle and chassis, Hydraulic operated side
shifting is available with a choice of fork sec-
tion, style and attachment type.
Electrical system
The main truck`s electrical system is 24 volts,
this potential is delivered by two 12 v 95 AH
batteries connected in series, Charge is provi-
ded by the engine mounted alternator and the
charge current is controlled by a solid state
rectifier.
Electronic/electrical installation
Parker control system allow:
- sensitive, smooth driving and reversing,
- automatic engine speed control to match the
hydraulic power requirements,
- fast service due to self-diagnostics,
- greatest possible operational reliability.
Driving cab
The steel frame of the driver`s cab has been
constructed to function as the load guard and
has been tested to exceed the International
safety standards. Driver entry is provided via
the steps located to the left side of the truck.
Steps are also fitted to the right side of the
truck for access. The right cab door can to be
used as an emergency exit and is provided
for the use of a passenger where the optional
passenger seat is fitted and located to the rear
left of the cab floor.
