Yale Hollow cylinders YCH

Double-acting with hydraulic return,

capacity 33 – 140 t

Basically, the applications are the same as for the singleacting 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.
