### Crash buffer

###### OVERRIDE PROTECTION

##### Crash buffer

##### Crash buffer

##### Crash boxes provide an incredibly high energy absorption capacity. They operate in parallel with the coupler and are usually combined with anti-climb devices to achieve optimal structural collapse, as they are not designed to transfer high vertical and lateral loads.

##### Product features:

- Non-reversible energy absorption (must be replaced after use)
- Not velocity dependent
- Almost 100% efficiency
- Absorbs the remaining impact after the initial collision
- Shape can vary to fit available space
- The product is used in combination with coupler release/shear bolts to ensure that the coupler is released in a controlled manner and pushes through the towing pocket without affecting the crash boxes or cab structure

### Anti climbers

###### OVERRIDE PROTECTION

##### Anti climber

##### Anti climber

##### Anti-climbers are designed to prevent vehicles from climbing over one another in the event of a collision. The product can be a plate or beam for direct mounting to the vehicle coach or in combination with a tube for plastic deformation. In the case of energy absorption, we offer you a full package of crash buffer technology.
