Flat Jacks and Specialist Jacking Systems

Hydra-Capsule low height flat jacks range from 8 to 345 tons capacity, the low height jack is capable of exerting extremely high trust forces. They are normally used by the construction industry for a multitude of applications, such as, lifting heavy structures, stressing operations, transferring existing loads to temporary or permanent supports and permanently pre-loading bridge bearings. Due to their design, they are not only light in weight but require a minimal installation gap or just a few centimetres, when selecting a flat jack, the ideal working range should be about 75% of the jacks capacity.

Permanent Units

When flat jacks are installed permanently, the procedure is similar to temporary installation except that a different pumping system is adopted. Once installed, they are inflated using a high pressure injection system, epoxy resin or grout can be injected, but grout filled units are normally recommended in order to meet the current day environmental and fire regulations. Its essential that the grouting operation is carried out quickly and efficiently and we would therefore strongly recommend that our experienced Engineers carry out such operations as mistakes can prove to be expensive. We provide a full design, manufacturing and flat jacking installation service offered throughout the UK and Europe.
