YCH Hydraulic Hollow Cylinder – Double Acting with Hydraulic Return

Ranging from 33tonne – 140tonne.
YCH Double-acting Hydraulic Hollow Cylinders with Centre Hold Design and hydraulic return. On request we supply special hollow cylinders with pulling capacities up to 600 tons.

Operating Pressure: 700 bar.
Models: YCH33/150, YCH33/250, YCH62/250, YCH93/250, YCH100/40, YCH140/250

Due to the centre hole design a threaded rod can be placed through the hollow cylinders so that extremely high pulling forces can be achieved for applications such as pre-stressing of anchor bolts, removal of axle bushings, extracting tubes and with puller sets for general heavy duty pulling jobs.

Includes: saddle, mounting threads and female coupler half.

Basically, the applications are the same as for the single-acting hollow cylinders shown on the opposite page, but for this model range the return of the piston is done hydraulically by means of the second oil port. These double-acting hollow cylinders are used when the piston needs to be retracted quickly e.g. with high-cycle pulling applications.
