The hydraulic bolt stretchers are the world’s advanced bolt pretightening and dismantling equipment. The hydraulic bolt stretcher is widely used in the pretightening of large-diameter bolts for its simple operation, simple operation, safety and stability. With the help of the hydraulic power provided by the ultra-high pressure hydraulic pump and the elastic range of raw materials, the bolts are stretched in the elastic deformation area to achieve the purpose of fastening or disassembling.

Because of the large transmission energy, hydraulic pressure is easy to convey and configure, which is frequently used in production and civil industry.
In the light textile industry, hydraulic technology is used in plastic injection molding machine, rubber vulcanization machine, paper machine, printing machine and textile machine.
In the machine tool industry, 85% of the transmission system of the machine tool selects the hydraulic transmission and control functions, such as grinder, milling machine, planer, broaching machine, press, shearing machine and combination machine tool, etc.
In the metallurgical industry, the electric furnace control system, the rolling mill control system, open hearth charging, converter control and blast furnace control all adopt hydraulic technology.
In the field of work machinery, hydraulic transmission is also widely used, such as excavator, tire loader, truck crane, crawler bulldozer, roller, etc.
Hydraulic off-road vehicles, hydraulic dump vehicles, Hydraulic Pullers, combine harvesters, etc. all use hydraulic technology. The above is the application of hydraulic technology of hydraulic bolt stretchers in various industries.
