■ A-4.2 DESCRIPTION OF THE MAIN
COMPONENTS
Chassis
Made of high tensile steel to improve robustness and
durability, it is equipped, at the front, with two
independent outriggers. A hydraulic cylinder between
chassis and rear axle allows compensating side slopes
up to ± 6°.
Hydrostatic transmission unit
Closed circuit hydrostatic transmission with continuous
speed adjustment, mainly consisting of:
-
a variable displacement pump connected to the
thermal engine by an elastic joint
-
a variable displacement motor connected to the
power divider-gearbox.
-
a hydraulic oil filter, placed on the injection line from
the tank
-
a water/oil heat exchanger to cool the circuit down.
This transmission with permanent 4 wheel drive
improves the traction force, thus resulting in an
increased climbing ability on slopes up to 60% at a
max speed of 35 km/h.
Power divider/Two-speed gearbox
The power divider/mechanical gearbox has two speeds
that can be selected by pressing the relevant button in
the driving cab, a work speed and a travel speed.
Speeds can only be selected when the machine stands
still. From the gearbox, through two Cardan shafts,
motion is transmitted to the front and rear axles fitted
with differentials.
Axles
Equipped with an automatic differential lock acting on
the rear axle which lets the machine move also on low
grip grounds. The front axle is the steer type; the rear
axle is the steer/oscillating type. When the high speed
is engaged, only the front wheels are allowed to steer.
Brake circuit
The brake system is the multidisc type in oil bath, with
self-adjustment, built in the front and rear axle and
acting on every wheel. The pedal directly acts on the
brake pump which delivers oil to the blocking cylinders
through a line with a pressure accumulator.
Steering
Servo-assisted steering system with extremely reduced
turning radius and three steering modes (T-WAY).
Handler with telescopic boom GTH-4013
GENERAL INFORMATION
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.
Overload warning system
The machine is equipped with a system controlling the
longitudinal stability which enables the operator to work
under absolute safety conditions. A bar with green,
yellow and red LED's indicates the percentage of
applied load with respect to the maximum payload of
the machine. When the second red LED comes on,
the machine movements are blocked, except for boom
retraction, and an audible alarm starts sounding to alert
to the risk.
Telescopic boom
In order to improve visibility, the boom is placed under
the visual angle of the operator. Made of high tensile
steel, it consists of two telescopic sections sliding on
long-life pads, easily accessible for maintenance. The
attachment holding plate with a 138° inclination is
equipped with a hydraulic coupling system that can
be operated from the driving place.
Boom hydraulic circuit
It consists of a gear pump connected to the thermal
engine which, through a valve, distributes oil to the
hydraulic drive and an electro-proportional main valve
for the following functions:
-
-
-
-
-
Driving cab
Large and comfortable cab mounted on vibration-proof
supports to improve the driver's comfort. Adjustable
seat with air-suspension and built-in armrest. User-
friendly dashboard. Multipurpose joystick with electro-
proportional control and ergonomic handle. The cab
comes complete with connections for the A/C system
and the CD player-radio set. Cab complies with
standards ISO 3449 and EN 13510 (ROPS and FOPS).
