CYLINDER GP - FRAME LEVELING
The frame leveling cylinder is located at the front of
the machine on the right side. T he head end of the
cylinder is attached to the machine frame, and the
rod end is attached to the front axle.
The frame leveling cylinder allows the machine frame
to be levelled i
n order to improve the stability of the
machine during operation.
STABILIZER CYLINDERS
The stabilizer cylinders are located on the stabilizers
at the front
of the machine. The head end of the
cylinder is attached to the stabilizer frame and the
rod end is attached to the stabilizer leg.
The cylinders extend in order to lower the stabilizers
and the cylinders retract in order to raise the
stabilize
rs.
STABILIZER SYSTEM
Stabilizers are used to increase the stability of the
machine during stationary lifting operations. The
stabilizers are used when the machine is lifting heavy
loads or whenanaccess platform is installed onthe
machine.
Independent operation of the stabilizers allo w s the
machinetobele
veled when the machine is operating
on uneven ground.
Stabilizers a
re installed as optional equipment o n
TH360, TH460 and TH560 machine s only. Stabilizers
are not available on TH350 machines.
Valv e Group (Stabilizer)
(1) Flow control v alve ( stabilizer)
(2) Control valve (left stabilizer)
(3) Control valve (right stabilizer)
The valve group (stabilizer) is located in the center of
the stabilizer frame at the fr ont of the machine.

VALVE GP - LOAD CONTROL (STABILIZER CYLINDERS) (LOCK)
The load contr ol valves are attached to the casings
of the stabilizer cyli nders.
The load control valves lo ck oil into both sides
of the cylinders in order to hold the cylinders in
position when the cylinders are stationary. T he valves
also prevent the stabilizer legs from collapsi ng if a
hydraulic hose bursts.
VALVE GP - STABILIZER CONTROL
(1) Flow con tr ol valve (stabilizer)
(2) Control valve (left stabilizer)
(3) Control valve (right stabilizer)
The valve group (stabilizer) is installed in the center
of the stabilizer frame at the front of the machine.
The valve group (stabilizer) consists of the flow
control valve (stabilizer) (1), the control valve (left
stabilizer) (2) and the control valve (right stabilizer)
(3).
The flow control valve (1) contro ls the flow of oil
into the stabilizer cylinders and out of the stabilizer
cylinders.
Stabilizers are used in order to improve the stability
of the machine.
