PLATFORM STABILIZATION SYSTEM
- The stabilization is effected with a slave cylinder:
- mounted under the platform and controlled by the master cylinder
- the levelling of the platform depends on the tightness of the stabilization system valves
- the system consists of the following parts:
- If the platform lowers itself at the front edge, the reasons can be:
1.
a leak in the slave cylinder load regulating valve (at piston rod), leaking in the direction of the
electrically actuated directional valve (which valve is not conceived to be tight)
2. an internal leakage in the cylinder
-If the platform lowers itself at the rear edge, the reasons can be:
1.
a leaking double load regulating valve (4) on the piston (lower) side of the slave cylinder, letting
through in the direction of the electrically actuated directional valve (5) (which valve is not
conceived to be tight)
2. an internal leakage in the cylinder.
A leak leads to a lowering of the platform until the load regulating valve (3) under the platform closes.
The closing is caused by a reduction of piston rod side pressure, reaching the opening ratio 5:1.
If the valves are leaking, please refer page 39 (hold- and load regulating valves)
Recommended settings, load regulating valves:
- Double load regulating valve (4), opening pressure 25 MPa (250 bar) (3600 psi)
- Load regulating valve (3) beneath the platform, opening pressure 21,5 MPa (215 bar) (3100 psi)
Do not change the valve adjustment settings.
