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.
