Prestressing hydraulic jack refers to a light lifting device that uses a rigid jacking member as a working device to lift heavy objects in a small stroke through the top bracket or the bottom bracket. prestressing hydraulic jacks are mainly used in factories, mines, transportation and other departments for vehicle repair and other lifting and support work. Its structure is light, sturdy, flexible and reliable, and can be carried and operated by one person.
There are hundreds of models of prestressing hydraulic jack for sale. Through the lifting and contraction of the piston, it can achieve the functions of lifting, lowering, stretching, and retracting during operation. It is a simple and convenient general tool. After years of development, performance has been greatly improved, and many details have been more and more humanized design. We still need to know the difference between various jacks in use, and choose the hydraulic jacks of the appropriate specifications in order to play their due functions.
In Leadcrete prestressing hydraulic jack finished product warehouse, we see various types of prestressing hydraulic jacks with different specifications, which are also diverse in appearance.
The first is the change in height. With the increase of the rated bearing capacity of the same type of jack, the wall thickness of the cylinder is also getting larger and larger, and the height is also increased. Due to the space limitation of the use occasion, the height of the jack body is also adapted to the size of the space. The lowest body height is only 30mm; there are also double-acting jacks up to 1219mm.
The number of oil inlets and outlets can distinguish between single-acting and double-acting. The piston rod of single-acting jack is retracted by spring or heavy load; the piston of double-acting jack is controlled by hydraulic pressure. There are micro-tops with a carrying capacity of 5T; there are also large-tonnage jacks with a capacity of 1000T. In addition to the ordinary solid rod, the central piston rod also has a hollow jack with a central piston, which is used for occasions requiring tension.
In addition, according to the need, the prestressing hydraulic jack can be equipped with aluminum alloy handles to increase the lifting lugs, which is convenient for on-site use, carrying and lifting. In order to meet the needs of special working conditions, some hydraulic jacks are equipped with threaded assembly holes at the bottom of the cylinder body, which can be used as a matching. Equipped with a spherical saddle for the jack to adapt to uneven components.
In pipe jacking construction projects, we generally use long-stroke jacks (there is a jack for engineering jacking). The thin top is suitable for places with extremely narrow spaces, such as the lifting of large rolls in steel mills, welding structure adjustment, and other mechanical maintenance lifting. In addition, the occasion of bridge jacking generally uses multiple thin jacks to control simultaneously, precise jacking.
The hollow jack is used when the traction rod or steel cable is required to pass through the entire hydraulic cylinder. Its unique center hole design can complete the operation of backward traction and forward extrusion. For example: oil field oil pipeline maintenance, large heat exchanger assembly and use, large windmill synchronous lifting and translation, etc.
Tension jacks are mainly suitable for the construction of various prestressed concrete structures and highway, railway, power station, bridge construction, rock and soil anchoring, landslide treatment, overall lifting of large heavy objects, continuous thrusting of super-large parts, disassembly of interference fit tools, etc. Pull jacks are suitable for occasions requiring tension and closing, for example: shipyard propeller installation and lifting.
As the carrying tonnage increases, so does the price. The increase in volume and the increase in raw materials are the basis for the price increase. The large tonnage also means that the requirements for raw materials are also increased. The difficulty of processing is a basic consideration for jacking. We are well aware that hydraulic jacks with moderate prices and high cost performance are the products that the public wants. Therefore, we are constantly improving the production process while providing customers with an excellent product, using the most suitable method to provide Cost-effective jack.
