Hi-Force 'HHS' Single Acting Hollow Piston Hydraulic Cylinders, from 11 to 102 tonnes, Stroke Length 25 to 152mm

This 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, used extensively in post-tensioning and pre-stressing applications as well as testing of various bonded or mechanical anchoring systems.

Can also be used for general lifting applications, when fitted with readily available interchangeable hardened steel piston rod saddles.
