CE-Type / Crash Element

Deformation Tube / COMPENSER®

With the CE-Type, LEBEN provides a maintenance-free deformation tube (so-called crash element) for emergency use, e.g. as fall protection.

Industrial Deformation Tube

The COMPENSER® of the CE-series is a non-reversible maintenance-free shock reducing element which can be used for emergency use, for example as a fall protection. If necessary, several deformation tubes (so-called crash element) can be installed in parallel as end stops.


  • installation position: any
  • energy absorption is possible in pull direction & in push direction
  • very short design
  • high buckling safety
  • maintenance-free
  • non-leaking
  • rear flange
  • surface galvanized or painted
  • variable progression of the reaction force over the stroke possible, e.g. optionally constant reaction force over the entire stroke, increasing reaction force in the beginning stroke range, or staggered progression
  • extreme temperature ranges
  • energy absorption up to 700 kNm

The crash element is attached to the support structure using the flange 3. In the event of an impact, the stamp (acting as a mandrel) 1 enters the deformation tube 2 and expands it. The initiated energy is converted into deformation energy and by means of friction into heat energy. The combination of deformation and friction determines the reaction force level. 

The maintenance-free CE-series crash element is a cost-effective irreversible shock reducing element for emergency use. However, it can only be used for a one off impact, e.g. as a fall protection.
If necessary, many crash elements can be provided in parallel.
