Hi-Force 'HDA' Double Acting High Tonnage Hydraulic Cylinders, from 25 to 520 tonnes, Stroke Lengths 152 to 330mm

The HDA double acting cylinder range offers the utmost in versatility and durability. Specifically designed for heavy duty lifting, construction and maintenance applications as well as presswork and industrial production, the double acting design provides substantial pulling force in the piston retraction mode as well as providing fast, controlled retraction for continuous duty cycle operation.

All models up to 203 tonnes are supplied with flat saddle, piston rod threads and collar threads as standard.

Models from 326 tonnes and upwards are supplied without collar thread and piston rod thread, however include replaceable tilting saddle as standard.
