Product Features
Primarily designed for Grade 10.9 high-strength bolts.
Maximum operating pressure: 150 MPa.
Automatic rapid-return mechanism significantly reduces operator effort and improves working efficiency.
The RES Series two-stage hydraulic bolt tensioner is specifically designed for demanding applications with restricted installation space, particularly in wind power applications.
Based on patented technology, the RES Series includes compact single-stage and two-stage hydraulic bolt tensioners, providing a comprehensive bolting solution for difficult and space-limited applications.
Red over-stroke warning line with three-stage safety protection helps ensure operator safety.
The same tensioner body can be used for tightening or loosening bolts of different sizes by replacing the corresponding tensioning head and nut rotating socket.
