About Climbing Jacks

Using double acting hydraulic jacks, the system ‘climbs’ on stacks of Ekki timber blocks. The Ekki timber stacks are located within a guide frame and built up systematically in 90mm stages after each stroke to raise to the required level. This enables the raising or lowering of heavy loads through greater distances.

All our Climbing Jacks are tested, certified and calibrated by our in-house hydraulics experts before every hire. If required, our hydraulics team will also install and operate the jacks for your project.

Available to straight hire or as part of a design.
