Hydraulic Strand Jack lifting system |Bridge Prestressed Machinery

The lifting jack is composed of an upper clamper, a main top, and a lower clamper. The upper and lower clampers are responsible for clamping and loosening of the steel strand, and clamp the steel strand on the upper clamp anchor (hereinafter referred to as tight anchor). In the state where the lower holder anchor loosens the strand (hereinafter referred to as the loose anchor), the main top extension and the retraction cylinder move up and down with the weight, and the anchoring and upper loosening state under the anchor bolt, the main top extension, Reducing the cylinder actually does not do work, the heavy object stops at a certain height, this stage stretches, shrinks the cylinder only to prepare for the next work step to promote, the decentralization. In order to achieve the coordination of these actions, the upper holder is provided with an upper anchorage and an upper anchor sensor

Description of hydraulic strand jack system:

The motion of the cylinders is driven by hydraulic power packs. They can be electric or diesel powered. Our sophisticated SCC software program synchronizes the motion of the strand jacks and adjusts the motion to the loads per lifting point.

Strand jacks lifting are available with two types of strand: a standard strand of 15,7mm and compact strand of 18mm. The 15,7mm strand can work with a dynamic load of 110kN. The 18mm strand can work with a dynamic load of 155kN. The number and type of strands used in a jack determine the safe working load of a jack. For lifting applications strand jacks are calculated with a 2,5 safety factor against breaking load to working load.

Strand jack lifting system are available from 30 up to 1.000 tonne capacity. We also provide a full range of accessories like a strand guide, strand dispenser and recoiler. All systems are certified and tested under Lloyd's witness. Each installation is delivered with an instruction and operation manual in English.
