CYLINDER GP - FRAME LEVELING

The frame leveling cylinder is located at the front ofthe machine on the right side. The head end of thecylinder is attached to the machine frame, and therod end is attached to the front axle.

The frame leveling cylinder allows the machine frameto be levelled in order to improve the stability of themachine during operation.

STABILIZER CYLINDERS

The stabilizer cylinders are located on the stabilizersat the front of the machine. The head end of thecylinder is attached to the stabilizer frame and therod end is attached to the stabilizer leg.

The cylinders extend in order to lower the stabilizersand the cylinders retract in order to raise thestabilizers.

STABILIZER SYSTEM

Stabilizers are used to increase the stability of themachine during stationary lifting operations. Thestabilizers are used when the machine is lifting heavyloads or when an access platform is installed on themachine.Independent operation of the stabilizers allows themachine to be leveled when the machine is operatingon uneven ground.

Stabilizers are installed as optional equipment onTH360, TH460 and TH560 machines only. Stabilizersare not available on TH350 machines.

Valve Group (Stabilizer)

(1) Flow control valve (stabilizer)(2) Control valve (left stabilizer)(3) Control valve (right stabilizer)

The valve group (stabilizer) is located in the center ofthe stabilizer frame at the front of the machine.

VALVE GP - LOAD CONTROL (STABILIZER CYLINDERS) (LOCK)

The load control valves are attached to the casingsof the stabilizer cylinders.

The load control valves lock oil into both sidesof the cylinders in order to hold the cylinders inposition when the cylinders are stationary. The valvesalso prevent the stabilizer legs from collapsing if ahydraulic hose bursts.

VALVE GP - STABILIZER CONTROL

(1) Flow control valve (stabilizer)(2) Control valve (left stabilizer)(3) Control valve (right stabilizer)

The valve group (stabilizer) is installed in the centerof the stabilizer frame at the front of the machine.

The valve group (stabilizer) consists of the flowcontrol valve (stabilizer) (1), the control valve (leftstabilizer) (2) and the control valve (right stabilizer)(3).

The flow control valve (1) controls the flow of oilinto the stabilizer cylinders and out of the stabilizercylinders.

Stabilizers are used in order to improve the stabilityof the machine.
