With the Yale YCH double-acting hollow hydraulic cylinders, 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. Like the YCS cylinders, the YCH range have a centre hole design where a threaded rod can be placed through so that extremely high pulling forces can be achieved. Hollow cylinders are used as the power component within hydraulic puller sets, for prestressing anker bolts, removing axles, shafts, bushings, extracting tubes, as well as for heavy-duty pulling applications.
