Protection of main cylinder
The protection circuit of the main cylinders protects the main cylinder’s piston rods from
buckling. The protection circuit comprises a tilt indicator and a pressure relief valve. If the
tilt is greater than set angle value, the working pressure is restricted to 11 MPa (110 bar)
and the backwards movement of the container may stop.
If this does take place, check that the movement of the platform rearward is free from
obstructions.
