Energy absorption

The objective of the test was to determine the maximum amount of energy wich the Softstop-system can absorb during an impact at a height of 50 cm, without failure i.e. breaking, bending and/or cracking of the system.

Results:

Type 1: 1621 Joule
Type 2: 2667 Joule
Type 3: 12934 Joule

The table below gives the “holdpower” of just 1 Softstopelement with a frontal impact.
A rigid connection of 2 Softstop-elements gives the double “holdpower” etc. Ask our advice.
