Component units
z Sound-insulated operator’s cab with excellent all-round visi-
bility. The non-slip, substantial steps provide convenient ac-
cess to the cab.
z Centrally positioned steering column.
z Clearly arranged instrument panel.
z Engine – Volvo TAD720VE (standard) six-cylinder, four-
stroke, turbocharged diesel engine with direct injection and
thermostatically controlled water cooling.
z Gearbox with torque converter
– Constant-mesh gearbox in which hydraulically actuated
clutches for the different gears. The clutches are electri-
cally operated.
– Torque converter, which is a hydraulic coupling that ampli-
fies the output torque on an increase in load. Torque con-
version takes place smoothly and steplessly throughout
the engine speed range.
– Oil cooler connected to the engine cooling system for
cooling the oil in the gearbox and torque converter.
– Oil pump which supplies oil under pressure to the gearbox
and torque converter.
– Full-flow oil filter for effective cleaning of the gearbox oil.
z Drive axle with two-stage reduction - in the differential and
the hub reductions.
– Oil cooled hydraulic brakes for the foot brake, e.g. Wet
disc brakes.
– Disc type parking brake applied by a sturdy spring and
released by hydraulic oil pressure. Tha parking is electri-
cally activated by a switch in the operator’s cab.
z Hydraulic system with
– Hydraulic pumps connected to take-offs on the torque
converter. In the standard version, the system has one
pump for lift and one pump for other working hydraulics.
Some machines have a separate system for side-lift which
is then fed by a separate pump.
The optional cab tilt is also fed by a separate pump.
– Main valve for controlling the main hydraulics. The valve
is controlled hydraulically from the cab.
– A high pressure filter after each pump for effective clean-
ing of the hydraulic fluid before it is fed to the system.
– Steering valve (Orbitrol) - flow-control valve which sup-
plies hydraulic fluid to the steering cylinder.
– Oil cooler with electrically powered fan.
z Steered axle with pendulum mounting and double-acting
steering cylinder.
z Sturdy clear-vision mast.
– Outer mast with hydraulically controlled forward and back-
ward tilting.
– Tilting cylinders with back-pressure valves to prevent the
load from tilting the mast forward.
– Inner mast with support wheels that carry the axial forces
on the mast. Sliding plastic plates to carry sideforces.
Yoke with guide rollers for the hydraulic hoses and guide
sprockets for the lifting chains.
– Lifting cylinders - two cylinders mounted on the outer
mast.
z Carriage with:
– Support wheels to carry axial forces
– .Sliding plastic plates to carry side forces
