A COMPENSATING VALVE that limits the basket descent in the event the rigid supply
pipe is broken. The device is always functioning during normal machine operation.
!
Proceed as described below to restore the machine to normal operating conditions:
1. repair the damaged hydraulic hose and/or connections
2. fill and bleed the hydraulic circuit
3. lift the platform to the maximum height
If the hydraulic hoses that supply the track chassis levelling cylinders function in a faulty way
and suddenly change the track, dedicated PILOT-OPERATED CHECK VALVES prevent the
track from changing back (ref. Point 5.10.2 EN280).
!
To restore the machine to its normal operating conditions, repair the damaged hose/hoses
and restart the system
