Heavy Lifting Technology
Strand Jacks
Capacity 15 – 1250 ton
Stroke 250 – 600 mm
Maximum Operating Pressure 350 bar
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.
- Full control of lifting and lowering through SCC control
- Two sizes strand diameter: 15,7 and 18 mm
- Complete line of electric and diesel power packs
- Nickel plated telescopic pipes preventing bird caging
- Standard supplied with lifting anchor
- Automated locking – unlocking operation
- Special corrosion treated high endurance multi-use wedges
- Full range of accessories: strand dispenser, strand guide, re-coiler and strand tensioner
