Yale YCH Hollow Hydraulic Cylinders

Double-Acting with Hydraulic Return | 33 - 140 Tonnes | 700 bar | Centre Hole Design

The Yale YCH range comprises double-acting hollow hydraulic cylinders with a centre hole, enabling pulling and tensioning applications with rapid hydraulic retraction. Capacities span 33 to 140 tonnes at 700 bar operating pressure. The double-acting design provides faster piston retraction than the single-acting YCS, particularly valuable for high-cycle pulling.

Designed for high-cycle pulling and tensioning

Yale states the YCH applications are basically the same as the single-acting YCS but with hydraulic return via the second oil port. Use of the YCH is recommended when the piston needs to be retracted quickly, particularly with high-cycle pulling applications. For double-acting hollow cylinders, the 'capacity push' is equivalent to the maximum pulling force achieved with a tensioning anchor or threaded spindle.

Applications

Per Yale: mirror the YCS range applications with the addition of high-cycle pulling work where rapid retraction is essential. Yale notes that on request, special hollow cylinders with pulling capacities up to 600 tonnes are supplied.
