Abstract
The present invention relates to a system for preventing semitrailer collisions with a loading ramp (10). The system comprises a sensor (100) and guide block (200). The sensor (100) is configured for sensing when the rear end of a semitrailer (12) is approaching a loading ramp (10). The guide block (200) is adapted to be positioned on the ground, and is here shown positioned laterally to the opening of the loading ramp (10). The guide block (200) comprises wheel blocking means (210) configured for supporting the tread of a rear tire of the semitrailer (12). The wheel blocking means (210) is configured to move from a forwarded position relative to the loading ramp (10) to a retracted position relative to the loading ramp (10) as the semitrailer (12) is reversing towards said loading ramp (10). The sensor (100) is configured to send a blocking signal to the guide block (200) when the distance between the rear end of the semitrailer (12) and the loading ramp (10) is below a preset threshold, thereby blocking the movement of the wheel blocking means (210).
