9.2.2 Installation / Operation of stacking sets
-
Lift the load with the cylinder using the normal piston guard plate.
- Place the first stacking ring (item 7) centrally on the cylinder body by means of the forked lever.
Caution under load!
- Lower the load onto this stacking ring and retract the piston.
- Remove the standard piston guard plate from the cylinder. Caution under load! (refer to
chapter 7.1.1,).
- Place the first piston plate (item 8) centrally onto the piston body (using a forked lever).
- Completely extend the load again by means of the piston.
- Insert the second stacking ring (item 9) by means of the forked lever.
- Lower the load onto this stacking ring.
- Insert the nose of the second piston platein the corresponding hole of the first plate (use fork
lever!).
- Completely lift the load by means of the piston.
- Continue in this way...
10 Dismantling of components
For dismantling of the components reverse the installation sequence. Before final dismantling of
the devices it is absolutely necessary to ensure that:
——> the load is in a stable, immovable position,
<——
——> the drive motor/engine must be shut down, <——
——> all hoses have been depressurized: <——
- Switch selector valve on the power unit temporarily to “LOWERING”(pressure relief of hoses),
then switch back to the centre position.
- Disconnect the DEPRESSURIZED hoses in this order: :
——> hose, piston side
red,
——> hose, rod side blue.
11 Maintenance
11.1 Mechanical check
After each operating procedure the components must be checked for faultless operation
(clean them first if necessary):
-
Check whether each single piston retracts smoothly (cylinders/pistons O.K.?),
- Check whether there are any loose hydraulic screw connections on the devices and hoses;
tighten them if necessary.
- Check the mechanical parts, the valves and the hoses of power pack, control table and
cylinders for mechanical damage.
- Check whether the signs, warnings, operation and control symbols and other markings (colour
markings) are complete and perfectly legible.
- Check whether all safety covers (engine: protective cover, exhaust pipe cover), hoop guard
etc. are available and in perfect condition.
- Check the condition of the accessories (baseplates, header plates, etc.).
