Crane control and assistance systems

The crane control system is an integrated solution, an all-in-one approach for precise, safe and fast cargo handling. Fields of action:

• Motor and hydraulic management
• Safety and diagnosis systems
• Communication and information systems
• Machine data recording

The assistance system indicates the approach to the tipping lines and automatically stops operation before the operator unintentionally enters an unsafe zone. It assists the operator in leaving the danger zone without having to activate the safety bypass switch.

The Ground Pressure Visualization calculates the current ground pressure of the machine in real time and compares it with the specified safety limits of the relevant position.

The ground pressure is displayed in the operator's cab and the operator is permanently aware of whether the machine is situated in, or is approaching, a critical area.

The assistance system Vertical Line Finder allows the operator to detect and prevent side and front pull. The operator's monitor always shows whether the rope is in vertical position.

By pressing a button on the joystick. The load is moved horizontally at a constant height. During luffing the load always moves along the horizontal load path.

Short suspension lengths save time when moving loads to their intended position. Coordination is also simplified for multi-crane lifting.

When operating on floating platforms, the lifting capacities are automatically adjusted depending on the inclination of the barge.

The newest generation of crawler cranes are approved for personnel lifting. This mode is selected using a separate key switch.

Thanks to the EC type approval certificate of the Liebherr crane for the occasional lifting of persons, local approval from an acceptance authority is no longer required by the crane operator.

The statutory emergency generator and emergency controls required for personnel lifting are offered by Liebherr as a simple Plug-and-Play solution. In case of emergencies, the crane availability can be restored within a few minutes.
