​Crash boxes offer a very high energy absorption capacity. They work parallel to the coupler, and are typically combined with anti-climbers for optimal structural collapse, because they are not designed to transfer high vertical and lateral loads.​

Capacity​

• Stroke: 50-1000mm​​
• Force: 200-3000kN

Features

• Non-reversible energy absorption (must be replaced after use)
• Non-velocity sensitive
• Close to 100% efficiency
• Absorbs residual impact after initial collision
• Shape can vary to fit the space available
• Release/shear bolts ensure the coupler releases in a controlled manner and pushes through the train pocket without interf ring with crash boxes, or the structure of th​e cab
