specifically designed for load lifting purposes, and by
pulleys and pins necessary to the chains to properly
operate.
At the top of the inner section a load handling
attachment articulation is provided with a rotating
carriage, which can be easily interfaced with a
number of different attachments, and which is
activated by another specific cylinder.
This cylinder is hydraulically linked to another
cylinder, hinged between the boom first section left
side and the slewing turret bottom plate, providing an
automatic forks leveling mechanism which maintains
the forks automatically leveled when the boom is
moved up and down.
The different attachments selected for this machine
can be easily replaced and are secured by a
mechanical pin (standard feature) or by a hydraulic
quick lock/unlock cylinder (optional).
The boom cylinders described before are driven
through a main valve which is electrically controlled
through a main joystick lever located on the right
armrest of the operator's seat. This valve is located in
the rear area of the chassis, immediately underneath
the boom hinge articulation.
Another hydraulic valve, on/off type, electrically
actuated and located inside the engine compartment,
controls the front stabilizers, hinged on the front area
of the machine and actuated by specific hydraulic
cylinders hinged between the chassis and the
stabilizers legs, and the chassis lateral leveling
system, activated by another specific cylinder hinged
between the right side of the chassis and the front
axle.
The operator can activate the stabilizers and the
chassis leveling through electrical switches located
on the left dashboard panel inside the cabin.
The other main controls available in the operator's
cabin are the steering wheel (to control the machine
steering function), the service brake pedal, the
parking brake mechanical lever and the two-speed
gear box shifting switch.
The steering wheel is mechanically connected to
a steering unit which feeds the steering cylinders
installed on the front and rear axles in such a way
the steering angle is proportional to the steering
wheel turns.

Description Of The Machine
GTH-4013 SX - GTH-4017 SX - GTH-4013 EX - GTH-4017 EX
The service brake pedal is linked to a brake pump
which is hydraulically powered by the third pump
installed on the engine distribution PTO and,
according to the stroke of the pedal, generates a
hydraulic pressure activating the service brakes disks
package (wet type) which is installed inside the front
and rear axles and works on the axle internal shafts.
The same brake disks package installed on the
rear axle is operated by the parking brake system
through an internal mechanism which is mechanically
actuated and hydraulically released. When the
parking brake is released, through the relevant
handle located in the operator's cabin immediately
on the left side of the operator's seat, a hydraulic
pressure is applied to the internal mechanism so
releasing the force on the brake disks. When the
parking brake is activated this pressure is removed
and the internal mechanism pushes on the brake
disks so developing the requested braking force.
Another hydraulic cylinder is installed on the back
left side of the chassis and is hinged between the
chassis and the rear axle. The aim of this cylinder
is to improve the lateral stability of the machine by
locking the rear axle when the boom angle is higher
than a specified value.
The operator's cabin is of full enclosed type and
provided with windshield and glasses to protect the
operator and to the maximum visibility.
The operator is seated on a cushioned and adjustable
seat and can operate the machine using the specific
controls which have been properly located inside
the cabin.
A dedicated dashboard is provided with all the
necessary controls and gauges necessary to
properly and safely operate the machine.
An automatic stability control system is provided
with a display located inside the cabin and showing
the stability status of the machine to the operator
and a strain sensor installed on the rear axle and
measuring the residual load on the axle.
The machine is also equipped with a complete set
of road lights allowing a safe circulation on public
roads in dark conditions.
A counterweight system is installed on the back area
of the chassis to improve the longitudinal stability of
the machine.
