Crash Boxes

Crash Energy Management outside the coupler
  • Crash box as element of Dellner Crash Energy Management System

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 Details

  • Stroke: 50-1000 mm
  • Force: 200-3000 kN
  • 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
  • Release/shear bolts ensure that the coupler is released in a controlled manner and pushes through the towing pocket without affecting the crash boxes or cab structure
