CE-Type / crash element
Deformation tube / COMPENSER®
With the CE-Type, LEBEN offers a maintenance-free deformation tube (so-called crash element) for emergency use, e.g. as fall protection.
The COMPENSER® of the CE series is a maintenance-free impact-reduction element that can be used as a deformation tube for emergency use, for example as fall protection. If required, several deformation tubes (so-called crash elements) can be arranged in parallel as an end stop.
Applications:
- Test benches, test fixtures, and crash test facilities
- Conveyor systems, conveyor technology, and material flow systems
- Lifting systems, vertical axes, and fall protection devices
- Actuators, control elements, and safety-related motion axes
- Motion systems
- Custom machines, custom machine design, and plant engineering
- Heavy-duty applications
- End stops, emergency stops, and overtravel protection in industrial plants
- Crash elements for rare, non-reversible overload and emergency load cases, for example in railway technology
- Energy absorbers for leak-free applications without hydraulic media
- Mounting position: any
- Energy conversion possible in the direction of compression & in tension direction
- very short design
- high buckling resistance
- Maintenance-free
- Leakage-free
- Rear flange
- Surface galvanized or painted
- Variable reaction force profile over the stroke possible, e.g., optionally constant reaction force over the entire stroke, increasing reaction force in the front stroke range, or a stepped profile
- Extreme temperature ranges
- Energy conversion up to 700 kNm
The crash element is mounted to the support structure via the flange 3. In the event of an impact, the plunger (which acts as a mandrel) 1 enters the deformation tube 2 and expands it by up to 20%.
The introduced energy is converted into deformation energy and, through friction, into thermal energy. The combination of deformation and friction determines the reaction force.
The maintenance-free crash element of the CE series is a cost-effective irreversible shock reducing element for emergency use. However, it can only be used for a single impact, but reliably protects the structure from destruction. Suitable, for example, as fall protection.
If required, several crash elements can be arranged in parallel.
