HHS - SINGLE ACTING HOLLOW PISTON CYLINDERS

Capacities from 11 to 102 tonnes
Stroke lengths from 25 to 152mm
Working pressure 700 Bar

The HHS single acting hollow piston cylinder range is extremely versatile for use in tooling, maintenance and tensioning applications. Specifically designed with a hollow piston to enable a rod or cable to be passed through the entire cylinder length for applications where a pulling force is required, the HHS range is used extensively in post-tensioning and pre-stressing applications as well as testing of various bonded or mechanical anchoring systems. HHS cylinders can also be used for general lifting applications, when fitted with readily available interchangeable hardened steel piston rod saddles.

>> Spring assisted return
>> Surface treated piston rod
>> Low friction bearing surfaces
>> Anti-extrusion seals
>> Optional piston rod saddles
