■ A-4.2 DESCRIPTION OF THE MAIN COMPONENTS
Hydrostatic transmission unit
This unit consists of parts which drive the machine
shifting, and namely:
- a variable displacement pump connected to the
thermal engine by an elastic joint
- a motor with variable displacement and automatic
adjustment in relation to the torque required,
directly applied on the axle by the power divider
- a hydraulic oil filter, placed on the injection line from
the tank
- a water/oil heat exchanger to cool the circuit down.
Engine
The thermal engine is equipped with a heat exchanger
which uses the engine oil as cooling medium.
Steering axles/(front and rear) differential gears
The differential axles transmit the motion to the wheels.
The locking device acting on the front axle enables
the machine to also move on slippery ground. Both
axles are steering; the rear axle is also of sprung type.
Tyres
The machine is equipped with tyres suitably sized for
the maximum load allowed on the handler.
When worn, they shall be replaced with new ones
having the same dimensions and loading capacity.
Load limiting system
The load limiting system installed on the vehicle
enables the operator to work within the rated limits of
the machine. A eight-LED display shows the stability
variation. When the seventh red LED lights up, all
machine movements are stopped, but for the boom
retraction.
Boom hydraulic circuit
It consists of a pump connected to the thermal engine
which, through a valve, delivers oil to the hydraulic drive
and an actuator for the following functions:
- boom lifting/lowering
- telescopic boom extension/retraction
- attachment rotation
- outrigger up/down-movement
It also feeds the following cylinders (supplied as
optional parts):
- attachment locking cylinder.
Handler with telescopic boom GTH-3512
GENERAL INFORMATION
