Description of Flat Jack

The flat jack itself consist of 2 main components; steel moulded capsule and a pair of thrust plates. The standard shape of a flat jack is round, however square and oval shape are available in special circumstances. The jack has an inlet and outlet connections to inject fluid and bled the capsule fully.

“The flat jack is the lowest height jack in the world that can exert forces up to 850 tonnes”

Depending of the application, an range of fluid can be injected into the jack(s) under pressure; water, oil, cementitious grout and resin. With an working pressure of a maximum 150 bars, with a stroke range from 25mm to 35mm dependant of the manufactured jack.

If existing structures have to be held up by means of piles or beams, it is sometimes necessary to preload the supporting section. This preloading can be effected with a flat jack, which is generally left behind in the structure.

Application of Flat Jacks:

• lifting of structures
• jacking of structures – pre-loading and inducing a permanent force to foundations, piles, beams, columns, bearings, seismic isolators and steelworks
• holding of structure – temporary propping / works, new foundations and  etc
• Weighing and Measure of forces
• Balance force loadings
