Hydraulic Strand Jack System
Description of hydraulic strand jack system:
The strand jack lifting technique originates from the concrete post tensioning principle. A strand jack can be considered a linear winch. In a strand jack, a bundle of steel cables or strands are guided through a hydraulic cylinder; above and below the cylinder are anchor systems with wedges that grip the strand bundle. By stroking the cylinder in and out while the grips are engaged in the anchors, a lifting or lowering movement is achieved.
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 *5,7mm and compact strand of *8mm. The *5,7mm strand can work with a dynamic load of **0kN. The *8mm strand can work with a dynamic load of **5kN. 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 *0 up to 1.**0 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 Lloyds witness. Each installation is delivered with an instruction and operation manual in English.
