Type PZK

Sensor-controlled safety wheel chock

The PZK wheel chock equipped with a position-dependent ultrasonic sensor and connected to the control unit via a robust cable guarantees safety during the whole loading and unloading process. As soon as one of the rear wheels of the lorry is blocked by means of the wheel chock, the leveller control function is “released” so that operation of the dock leveller can be started.


The wheel chock

  • can be used in each type of a heavy-duty vehicle.

  • can be easily installed at a later date.

  • constitutes a cheap addition to loading work safety systems.


Sequence of operation:

The dock leveller can only be operated if the lorry is blocked by means of the safety wheel chock. With the wheel chock being positioned, the lorry cannot accidentally roll away from the docking station.
