Worker Protection System II (WPS II)

Safety / assistance systems

Products in this segment include optional components which make a significant contribution to operator safety.

  • The Worker Protection System II (WPS II) is an assistance system meant to reduce and/or prevent severe injuries to the operator.


  • WPS II detects, during the lifting process, objects or persons in the hazard zone and stops the automatic lifting movement, if required. The emptying process can be continued manually afterwards.
  • The WPS II uses two different technologies to identify an object or a person that is too close to the container and/or is caught and lifted by the container.


  • An expert opinion on the installation and function of the Zoeller Worker Protection System II (WPS II) of TÜV Rheinland as of 27.08.2019 is available.
