DGUV Information 203-030 - Principle design rules for the use of transfer cars (in the corrugated board industry)

If bumpers are used the deflexion distance of the bumper has also to be larger than the stopping distance of the transfer car.

The actuation forces may not exceed 250 N. The final applied force that is reached when the bumper is compressed after the transfer car moving at maximum speed and load was stopped by the bumper may not exceed 400 N (→ see DIN EN 1525).
