60-600t Multi PC Strands Stressing Jack Post Tension Jack New Large Lifting Jack Equipment
Introduction of Synchronous lifting jack
Technical indicators: The technical indicators of a single lifting jack are as follows. According to the hydraulic lifting equipment composed of different hydraulic pump stations, the lifting speed can be 0-25 m/h. The system control adopts PLC, and the synchronization accuracy of lifting and lowering is ±10mm. . The above is the conventional configuration, which can be designed, modified and manufactured according to the user's requirements.

Working Principle of Synchronous lifting jack
The synchronous jacking system is composed of an electric motor, high-pressure hydraulic pump, fuel tank, operation control system, jack and oil pipe, diverter, etc.
The flow of a pumping station is output through the diverter and provided to each execution cylinder respectively. The displacement control system controls the lifting speed of each cylinder with load according to the feedback signal of each different measuring point, so as to realize the whole concrete continuous beam body. synchronous jacking action.
Applicable fields of Synchronous lifting jack
Widely used in the vertical hoisting or lowering of large-scale structural parts at home and abroad, such as the hoisting of steel box girders of bridges, the lowering of bridge piers and weirs, the hoisting or lowering of hanging blue, the hoisting of chimney steel inner cylinders of power plants or chemical plants, the hoisting of steam drums and stators of power plants, Gantry crane installation, aircraft maintenance garage, gymnasium, and other steel structures and other super-high and super-heavy large-scale structures.
Performance characteristics of Synchronous lifting jack
1) The lifting equipment is small in size, light in weight, large in carrying capacity, convenient and flexible in installation, especially suitable for small space or indoor large-tonnage component lifting;
(2), by expanding the combination of lifting equipment, the lifting weight, span and area are not limited;
(3) Using low-slack steel strands, as long as there are reasonable load-bearing lifting points, the lifting height is not limited;
(4) The lifting jack anchor has reverse motion self-locking, which makes the lifting process very safe, and the components can be reliably locked for a long time at any position during the lifting process;
(5) The equipment has a high degree of automation, convenient and flexible operation, and has various operation modes such as automatic operation, semi-automatic operation, single-point adjustment, and manual operation. The display has liquid crystal display, touch screen display, button operation panel display, etc., which is very intuitive. And the control system is equipped with a self-correction protection program, which will not cause a safety accident even if it is misused.
(6) Using this equipment for construction, the construction period is short, the cost is low, and the economic benefit is good
