TSH

Are systems to guarantee the preload in assemblies.
The TSH & SH have been born as a patented solution to guarantee the preload in assemblies
with high requirements, of big dimensions, with high reliability and quick easy use.
Its fastening as explained in the video is very simple:
1- The TSH is introduced with its lock bush and base washer.
2- The tension transmitters are introduced through the head of the TSH.
3- Assembly the puller on the TSH head.
4- Preload the system with the hydraulic puller and stretch the TSH.
5- Adjust the lock bush to the base washer to fix the obtained elongation.
6- Disassemble the puller and the tension transmitters from the TSH.
• The fastening fix up can also be done through shims as referred on other models of TSH.

- Reduced number of fixation elements with respect to torque control.
- Quick reaching of preload.
- Low dispersion.
- High stability of the preload.
- Low load distribution factor for the fixation element. Lower fatigue range.
- Achieving preload by the use of pressure tables.
- Insensitivity to bending moments.
- No twisting of the fixation element.
- Ease of assembly and disassembly.
- Simultaneous Assembly of fixation elements. Elimination of elastic interaction of close elements.
- Same assembly protocol for all metric sizes.
- Benefits of elongation, without the disadvantages of friction.
- Ease of verification of preload sustention. It enables maintenance actions, if necessary, based on accurate preload readings.
- Multiple reuse of the element. Ease preload reset by assembly process repetition.
- Insensitive to the type of fixation thread or its lead due to lack of friction in the tightening process. Potential increment of the preload capacity.
