GENERAL INFORMATION
■
A-4.2 DESCRIPTION OF THE MAIN COMPONENTS
Hydrostatic transmission
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 wheel torque required;
it is directly installed on the front axle together with
the two-speed gearbox
- a hydraulic oil filter, placed on the injection line from
the tank
- a heat exchanger to cool the circuit down.
Motion is transmitted to the rear axle from the gearbox
through a Cardan shaft.
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 move also on low grip grounds.
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.
Boom hydraulic circuit
It consists of a gear pump connected to the thermal
engine which, through a special valve, dispenses oil
to the hydraulic drive and a distributor for the following
functions:
-
boom lifting/lowering
- telescopic boom extension/retraction
- attachment rotation
- attachment locking
Braking circuit
It consists of an independent circuit: the pedal directly
acts on the brake pump which dispenses oil to the
front axle braking unit with discs in oil bath.
The parking brake, of negative type, acts on the braking
unit of the service brake. This brake is engaged every
time the handler's engine is stopped or pressing down
the light pushbutton located to the right of the driving
place.
Telescopic boom
The machine is equipped with a telescopic boom with
hydraulic-driven extension. The telescopes slides on
interchangeable pads made of wearproof material.
Driving cab
Type-approved driving cab in compliance with
standards ANSI/ASME B56.6-2002.
