6.5 Lift cylinder (Fig6.6)
The lift cylinder is of single-action piston type. It consists of cylinder body, piston rod,
piston and cylinder head etc. The bottom of the cylinder is connected with the cylinder
supporter of the outer mast by bolts and pins, while its top (i.e. piston rod head) is
connected with the upper beam of the outer mast.
The piston, fastened to the piston rod with spring wire is fitted with oil seals and
wearing on its outer periphery.
At the bottom of the lift cylinder there is a cut-off valve, which operates when the
high-pressure hose bursts for any reason to prevent the load form dropping from abruptly.
Bushing and oil seal assembled on the cylinder head, are used for support the piston
and prevent dirt from entering.
