1) The MSD hydraulic bolt tensioner is a tensioning device specially used in the wind power industry. It has a very good effect on the fastening and disassembly of bolts in different positions such as turbines.
2) MSD bolt tensioners are suitable for many wind turbines, such as wind turbines from Vestas, GAmesa, Goldwind, Shanghai Electric, Dongfang Electric and many other brands. For different types of wind turbines and bolts in different positions, TorcStark has a very suitable tensioner model to match it.
3) The maximum working pressure of MSD bolt tensioner is 150MPa. The ultra-high working pressure makes MSD tensioner enough to cope with various wind power projects.
4) MSD bolt tensioners are packed in wooden boxes. TorcStark stocks a large number of MSD 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.

Notes:
MSD-series bolt tensioners are designed for loosening and installing grade 10.9 high-strength bolt, according to 90% of the limit of extension 0.2.
Use the same bolt thread of the bolt tensioning head size which is next to the bigger cylinder (take M42 as an example, the MSD 45 can replace MSD 42), or with special design.
The single grade tensioner listed above is only a very small part of product line, more than 90% of tensioners need special design specifically according to production condition.
TorcStark is capable of customizing the most suitable product for your production needs with our established design and on-site utilizing experience.
