Product Description

Brief Introduction: 
Hydraulic synchronous lifting system for the overall lifting and declining was controlled by the computer. Bearing load through flexible steel strand,  strand jacks cluster, computer control, and hydraulic synchronous lifting principle were applied in this technology. And also being combined with modern construction technology to achieve synchronous lifting and declining of high tonnage, large span, large area Of the super-large equipment.
  1. The capacity, span, area are unrestricted with extended combination of Lifting equipment.
  2. Bearing load by flexible steel strand. Lifting height is unrestricted as long as got the reasonable load-bearing lifting point. 
  3. The reverse movement self-locking of steel strand jack's anchorage assures safe working, and can be long-time reliably locked at any location in the lifting process.
  4. Small size, light weight and high capacity,  that's particularly suitable for lifting high tonnage equipment in limited space or indoors. 
  5.  Features as highly-automatized, flexible operation, safety, reliability, wide application,  and versatility.
1.Safe working load of the jacks has been set at 40% of the minimum breaking load of the strand. (I.e. factor of safety = 2.5) 
2.Designed for use with both 18mm and 15.7mm diameter strands. 
3.Telescopic strand guide tubes through the full height of the strand jack to prevent buckling and 'birdsnesting' of the strands inside of the jack. Made from solid stainless steel for long life. 
4.Strand patterns used and the arrangement of top and bottom anchors have been designed for ease ofaccess to service the grips. All grips can be fully serviced in the middle of a lift with the jack fully stranded. 
5.Main cylinder pressure tested and certified to 150% of working pressure. 
6.Complete strand jack load tested and certified to 125% of safe working load. 
7.Double acting minijacks used for opening/closing the grips in the top and bottom anchors, which canbe fully replaced in
the middle of a lift if necessary without dismantling the strand anchors or cutting the strand. 
8.Pilot operated over centre valve fitted to the extension port block for controlled and synchronized load
9.Load holding valve fitted to the extension port block for safe holding of the load in the event    of a hose burst. 
10.Pressure compensated bleed valve fitted to the extension port block for very slow final lowering for precise alignment of the load and smooth transfer of load to supports. 
11.During a lifting operation the strand jack can be fully dismantled for repair with the load  held in thebottom anchor. 
12.Fitted with quick release hose couplings. 
13.Corrosion protection to all exposed and running surfaces for long life and suitable for use in a marin environment. 
14. Single strand tensioning plate fitted to the top of the jack.
