TorcStark®

1) ESD single-stage hydraulic bolt tensioner is mainly used for the fastening and disassembly of 10.9 high-strength bolts, and it can still operate normally under a pressure of 150MPa.

2) The ESD single-stage bolt tensioner is easy to use and easy to operate, with automatic return function and red over-travel warning function, which can greatly reduce the labor intensity of workers and ensure the safety of operators.

3) The ESD single-stage bolt tensioner is designed for disassembly and assembly of high-strength 10.9 grade bolts and is designed according to 90% of the elongation limit 0.2. If you need more tensile force, you need to use the next larger cylinder next to the same thread size of the bolt extension head in the table below (for example, for M42, use ESD45 instead of ESD42).

4) More than 90% of ESD single-stage bolt tensioners need to be specially designed according to the working conditions. TorcStark has many years of mature design and field use experience, and will customize the most suitable product for you.

5) ESD single-stage bolt tensioner can be double-packed, aluminum-plastic box plus wooden box. TorcStark stocks a large number of ESD single-stage bolt tensioners, which can be shipped immediately. The transportation time depends on the transportation method, and the shortest time is 3-5 days. TorcStark provides a one-year product warranty.
