Flat Jacks

Flat Jacks or Pancake Jacks are used for pre-loading steelwork and often used for bearing replacement, lifting and weighing structures with limited access. They can be used for temporary loading where water is used to inflate the jack, or permanent loading where water is used to preload the jack, and then pumped out and filled with grout. This then sets in place to allow for safe construction, once hardened the flat jack cannot be adjusted.

Their low profile means flat jacks are ideal for lifting, lowering, stressing and pre-tensioning in the tightest of spaces. The circular steel thrust plates ensure that pressure and loads are distributed evenly to hold structures securely in place.

All our flat 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.

Applications:

• Bridge Jacking
