Simple Chuck Type Hydraulic Jack
Simple chuck type (unfixing Holding-latch) hydraulic Jack is a double acting hydraulic jack (also known as hydraulic lifting machine) with upper and lower clamping heads divided into two bodies. It is suitable for lifting construction of various large storage tanks (steel) or other heavy objects. It needs to cooperate with the lifting rod to achieve reciprocating lifting work.

The jack comprises an oil cylinder and a piston, the upper and lower ends of the oil cylinder are respectively provided with an upper cylinder head and a lower cylinder head, and the upper cylinder head and the lower cylinder head are respectively provided with an oil inlet and outlet hole; The piston is arranged in the middle of the piston rod, the both ends of the piston rod respectively extend out of the upper cylinder head and the lower cylinder head, the piston rod is hollow, and the lifting rod axial through the piston rod, the lifting rod on the upper side and the lower side of the piston rod are respectively provided with a locking device.
Hydraulic lifting device (package unit) is evenly distributed around tank inner wall. Tank top and upper (the first layer) wall plates are lifted first and then install and weld wall plates of tank body. When oil enters hydraulic jack, upper clamp fastens and lifts lifting rod and expansion ring and mobilize tank to ascend upward. When oil returns to jack, upper clamp returns with piston and lower clamp automatically fastens lifting rod without gliding. Repeat the process and ascend welded tank till the last layer of wall plates are installed and welded.
Our hydraulic machinery manufacturing capabilities integrate design, development, and production of high-end hydraulic hoists and supporting products. These solutions are primarily utilized for the inverted lifting and installation of large-scale steel storage tanks.
With years of concentrated scientific research, our series of products have been widely adopted in various industrial projects, including inverted lifting, translation, jacking, and climbing operations. By combining professional engineering with strict management, we provide hydraulic lifting equipment that forms a complete jacking system, ensuring high efficiency and safety for installation engineering projects worldwide.
