Product Description
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 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.
Functions of hydraulic strand jack system :
hoisting large components and lifting construction components by reverse method.
Characteristic of strand jacks lifting:
(1) upgrading equipment is small in volume, light in weight, large in load capacity, convenient and flexible in installation, continuous lifting system, hydraulic synchronous intelligent climbing pole synchronous lifting system, especially suitable for small space or indoor large tonnage member lifting.
(2) by raising the equipment expansion combination, the lifting weight, span and area are not restricted.
(3) in the use of low relaxation steel strands, the lifting height is unrestricted as long as there is a reasonable load bearing point.
(4) lifting jack anchorage has self locking property of reverse motion, so that the lifting process is very safe, and the components can be reliably locked at any position in the lifting process.
(5), the equipment automation is high, the operation is convenient and flexible, with automatic operation, semi-automatic operation, single point adjustment, manual operation and so on. It shows the LCD display, the touch screen display, the button operation panel display and so on, very intuitionistic. And the control system has a self correcting protection program, even if the misoperation will not cause safety accidents.
(6) construction with this equipment, short period, low cost and good economic benefit
Scope of application: hoisting of large building components, hangar roof truss, bridge, power station equipment and offshore oil platform. It can also be used for hoisting heavy and heavy parts in other industries.
