Twin Type Hydraulic Bolt Tensioning Cylinder
A twin-tensioner hydraulic cylinder for simultaneous pre-tensioning of two closely spaced bolts, covering M16 to M52 with individually mountable bushings.
More Information
The ITH Twin Type merges two tensioners into a single cylinder, allowing simultaneous pre-tensioning of two bolted connections within a close axial distance. It covers a scope of M16 to M52, with two change bushings that can be mounted individually for easier assembly.
Key Features
- Two-tensioner merged design pre-tensions two bolted connections simultaneously.
- Two individually mountable change bushings simplify assembly.
- Modular design with a changeable support unit adapts to different applications.
- Integrated adjustment window allows tightening and loosening of nuts without removing the tool.
- ITH safety concept includes a patented cycle counter and patented safety fracture device.
Typical Applications
- Flange bolting requiring simultaneous, evenly distributed preload
- Applications with bolts spaced closely together
- Pressure vessel and pipeline connections
- Multi-tensioning setups for consistent joint quality
