  • The nose of the tool is placed over the pin tail and the trigger is pressed.
  • The tool jaws pull on the pull grooves clamping the joint tight before the collar is swaged into the locking grooves.
  • The pin tail breaks at a predetermined load leaving the finished joint

Quality Management

Application Examples

The German company CLAAS manufacture agricultural vehicles that fulfil the very highest standards of quality & performance. The company relies on TITGEMEYER products to keep meeting these standards.

Lockbolt pins and collars manufactured by TITGEMEYER join together the upper and lower housing of the elevator chain on CLAAS Avero combine harvesters.

This chain drives the conveyor that transports the grain from the inlet chute to the hopper.
The lockbolt system is the ideal solution to withstand high dynamic loads while performing its vital task of preventing any loosening of the joint.
