I. Scope of application of hydraulic bolt tensioner
Electricity, shipbuilding industry, metallurgy, coal mining, petrochemical, heavy machinery and other fields.

Second, the advantages of hydraulic bolt tensioner
1、General use of mineral oil as a working medium, the relative movement surface can be self-lubricating, long service life.
2, light weight, small size, small motion inertia, fast response speed.
3、Hydraulic transmission of various components, according to the need for convenient and flexible arrangement.
4、It can realize overload protection automatically.
5, easy to manipulate and control, can realize multiple bolts fastening at the same time. Save labor costs.
6、It is easy to realize linear motion.
7, it is easy to realize the automation of the machine, when using electro-hydraulic joint control, not only can realize a higher degree of automatic control process, but also can realize remote control.
8、It can be used as a hydraulic interference connection to apply axial force device, for top pressure installation.
