Automatic vehicle immobiliser system for locking lorries’ wheels while in dock during loading and unloading.

The self-locking system prevents the driver from accidentally starting up the lorry. A large steel cylinder, 400 mm off the ground, blocks the lorry’s wheel. It cannot be crushed or dragged.
The locking or unlocking system is activated when the dock door is closed. Avoiding accidents caused by falls. If the vehicle is not braked when unlocked, the system detects vehicle movement and it remains locked.
