EQUIPMENT HYDRAULIC SYSTEM
6.4.1 DESCRIPTION
Fig. 6-20 Pilot valve
The control system of the control valve is of a power assisted type with different levers for the functions: booms lowering/raising and bucket roll-back/dumping.
The control valve spools are actuated by hydraulic connections. The circuit pressure (30 bar) is ensured by a pressure relief valve equipped with an hydraulic accumulator.
It is possible to install, upon request, a third lever controlling a third spool of the control valve, in case it becomes necessary to mount a special type of equipment requiring a third hydraulic function.
A questo proposito, il supporto in cabina é predisposto a ricevere la terza leva di comando.
WARNING
The piloting system of the control valve is equipped with a safety device allowing its cuttingoff. Actuate the cut-off device to lock the control levers in neutral position when the equipment is not in use.
6.4.2 PILOT VALVE
The pilot valve is of a modular type and is composed of two valve assemblies connected by two screws. If the booms or the bucket lever is actuated, the plunger of the pilot valve moves to direct pressurised oil to the port of the equipment control valve selected, moving the corresponding spool.
