Bolt Tensioner

The working principle of bolt stretcher is mainly based on hydraulic transmission, using the Pascal principle to transfer energy. twelve The bolt stretcher applies direct external force to the bolt through a hydraulic cylinder, causing it to be stretched

Bolt tensioner generally consists of hydraulic pump, high pressure hose, pressure gauge and tension body. Among them, the hydraulic pump is the power source, the pressure gauge reflects the output pressure of the pump, the high-pressure hose connects the

Bolt tensioner is a special tool for tightening or dismantling bolts using hydraulic principle. By stretching the bolt, it is elongated within the elastic deformation zone and the bolt diameter is slightly deformed so that the nut can be easily loosened o

SL-TD single stage low stretcher series. A broad range of single stage hydraulic bolt tensioners designed for critical fastening applications in wind, steam and gas turbines.Single stage bolt tensioners are ideal for applications that are vertically limit

Ultra-thin design is more suitable for bridge shock-absorbing column replacement. The use of piston parts welding copper process is not easy to pull the cylinder, can be used repeatedly to create more efficient and cost-saving.

Two-stage Bolt Tensioners is a hydraulic tool mainly used for tightening and removing bolts. It is supplied with a hydraulic source through a hydraulic pump and uses the tensile force generated by the ultra-high pressure oil pump to elongate the bolt with

Ultra-thin design is more suitable for bridge shock-absorbing column replacement. The use of piston parts welding copper process is not easy to pull the cylinder, can be used repeatedly to create more efficient and cost-saving.

The STU series subsea bolt tensioner is a reliable and effective solution for tensioning subsea bolts. A cylinder of one size can be used with multiple threaded tensioning heads of different sizes. Threaded tensioning heads can also be ordered separately
