Hi-Force 'HFG' Single Acting Fail Safe Lock Ring Cylinders, from 50 to 1012 tonnes, Stroke Lengths 50 to 152mm
Hydraulic Lifting Cylinders with Locking Ring, Capacities from 50t to 1012t.
HFG / LRC-4852
This single acting failsafe lock ring cylinder range combines all the versatility and efficiency of hydraulic power with the safety of mechanical load support. Ideally suited for applications requiring sustained load holding for extended periods, such as bridge support work.
Features a single acting, load return piston, threaded throughout its stroke length to suit the threaded mechanical load holding lock ring. Simply jack up the load, wind down the mechanical lock ring until it comes into contact with the cylinder body, release the hydraulic pressure and sustain the load mechanically.
All models are suitable for vertical lifting only and are supplied with tilting saddles as standard to reduce the risk of side loading the cylinder.
For easy rotation of the load holding locking ring, we recommend the purchase of tommy bar(s).
- Capacities from 50 to 1012 tonnes.
- Stroke lengths from 50 to 152mm.
- Working pressure 700 Bar.
- Single acting load return design.
- Nitrocarburised cylinder and piston rod for corrosion protection.
- Low friction bearing surfaces.
- Load / Gravity return.
- Stroke limiting device: Restriction port.
- Anti-extrusion seals.
- Tilting saddle fitted as standard.
- Other capacities and stroke lengths available on request.
- Click for Hydraulic Pumps, 700 Bar.
