ZT TSD15 Heavy Lifting Strand Jacks
Buy  Xian (China)   22nd May 2020   Others

Use of ZT-TSD15 heavy lifting strand jacks: Strand jacks can be used horizontally for pulling objects and structures, and are widely used in the oil and Since multiple jacks can be operated simultaneously by hydraulic controllers, they can be used in tandem to lift very large loads of thousands of tons. Even the tandem use of two cranes is very difficult operation introduction of ZT-TSD15 heavy lifting strand jacks: The strand jack lifting technique 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 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 url:http://www.ztmineequipment.com ZT TSD15 heavy lifting strand jacks... ... read more »

Hydraulic Strand Jack And Tower Lift System
Buy  Xian (China)   19th Apr 2018   Others

Introduction of Hydraulic strand Jack and tower lift system: Power packs of Strand jacks and tower lift system have direct, panel mounted, monitoring It would be typical that a Fagioli operator might control a multi-jack lift or lower by means of two functional control levers on the power pack with the option of opening or closing hydraulic flow to all or any jacks by means of line valves. Maximum pumping pressure, hence jack lifting force, can be pre-set or altered at will by pressure control valves on the panel. Further electronic monitoring can display number of lift strokes completed and individual stroke positions at each jack. remote from the power pack to fully computerised systems, including automatic lifting and lowering capabilities The Advantages of Hydraulic strand Jack speeds; - Load is held mechanically not hydraulically at any time movement is stopped; - Movement can be stopped and held indefinitely at any point in jack lift for setting of weld gaps or the fitting of steelwork connecting bolts; - Automatic lifting and lowering without any personnel in attendance at the jacks ; - Easy re-distribution of the jack loads; - Minimal re-lubrication of gripping mechanisms - lifts of 90 metres and horizontal moves of 250 metres have Hydraulic Strand Jack And Tower Lift System... ... read more »

Precautions of post tensioning hydraulic jack: In addition to the provisions of the general prestressing technology, the following items should be paid attention to in the use of the jacks. 1. In order to ensure the accuracy of tension, the jack should be matched with the oil pump, the pressure gauge and the external high pressure hose, and the In the calibration, the active working state of the jack is taken as the criterion, the record is graded, the average value of the three measurements is taken, and the chart is made as the basis for the tensioning. 2, in the following cases, the jacks should be re calibrated (1) post tensioning jacks was dismantled and repaired; (2) the pressure gauge is in a collision or failure phenomenon. (3) when the new pressure meter is replaced; (4) the jack is used for a long time and reused. 3, Prestressed Post Tension Jack shall adopt No. 46 high Strictly prevent sand and dust into the jack, and reduce the number of disassembly and disassembly as much as possible. When the new oil pipe is used, do not connect directly with the jack oil Tsui. After unloading the oil pipe, the jack and the oil pump stress proof cap, in order to prevent the contamination from mixing. 5, the jacks should be operated for more than three times before the jacks are used in order to discharge the air in the oil cylinder. 6, Multi Strand Jacks should be regularly maintained If we find fault, oil leakage and scratches on the piston surface, we should stop using and repair. 7, Jack in the work process, the operator should stand on both sides, face direction prohibited to stand, so as to avoid accidents. 8, the working surface of the jacks should be cleaned regularly and kept Multi Strand Jacks... ... read more »

Hydraulic Jack With Manual Lock Nut Cylinder
Buy  Xian (China)   19th Apr 2018   Others

Introduction of Manual lock nut hydraulic jack Manual lock nut hydraulic jack using hydraulic power operate on the phenomenon that fluids produce the With these types of jacks, a fluid is contained within a large and small container, both of which are linked by tubes. With hydraulic jacks, smaller amounts of force are capable of lifting loads which would otherwise be impossible. The principals behind this type of jack was discovered back in the seventeenth century. Hydraulic jacks are commonly used to lift vehicles in order to conduct maintenance. While these jacks are capable of lifting heavier loads than mechanical jacks, they also have the drawback that the load will be lowered if the hydraulic power is removed from the jack. Operators must take care to ensure that hydraulic power remains in place while they are working with the jacks.
