Single Acting Low Height Fail Safe Lock Ring Cylinders, from 50 to 520 tonnes, Stroke Lengths 45 to 51mm

This low height single acting failsafe lock ring cylinder range combines all the versatility and efficiency of hydraulic power with the safety of mechanical load support, offering a sustainable lifting force in very confined work areas. Ideally suited for applications requiring load holding for extended periods, such as bridge support work.

The range features a single acting load return piston, threaded throughout its stroke length to suit the threaded mechanical load holding lock ring.

All models are suitable for vertical lifting only and are supplied with tilting saddles as standard.

For easy rotation of the load holding locking ring, we recommend the purchase of tommy bar(s).
