18.5 LOAD HOLDING AND LOAD REGULATION VALVES
Check of operation
1. To check the load holding valves of the outrigger cylinders for tightness, measure the
height of the chassis from the floor separately at each outrigger, and observe the height
in a few minute's time.
2. To check the tightness of the lifting cylinder's load regulation valve, drive the boom to a
position where its location can be reliably measured. Observe the possible movement of
the boom in a few minute's time.
3. To check the load regulation valve of the telescope cylinder for tightness, extend the
telescope and stop the movement at any position, measure the stroke and observe in a
few minutes time that the stroke does not change. (Note! Drive the boom to an almost
vertical position).
4. To check the load regulation valve in the levelling system of the platform for tightness,
put a load of about 100 kg onto the platform and measure the distance from the rear
edge of the platform to the floor. Observe in a few minutes time that the height position
does not change.
Service instructions
1. Remove and clean the valve.
2. Check the O-rings and replace them if necessary.
3. Put the valves carefully in place.
4. If necessary, replace the valve.
5. Do not change the pre-set values of the valves.
Support the platform, the boom system and the outriggers in a
position, where the load does not rest on the structure to be
repaired. Ensure that there is no residual pressure left in the
cylinders.
