Our Flat Jacks (also sometimes referred to as Pancake jacks), are used for pre-loading steelwork. Water is preloaded and then pumped out and filled with grout, which then sets. 

They have a low profile so can be used in the tightest of spaces. So are often used for bearing replacement and lifting and weighing structures with limited access.


Load bearing capacity: 79kN - 3393kN
Stroke limit 25mm
