Liebherr crane safety

  • Gradient Travel Aid assistance system helps to navigate slopes and inclines. It displays the crane’s center of gravity and warns the operator before the crane leaves the safe area.
  • Ground Pressure Visualization calculates the current ground pressure of the crane 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, making the operator aware of whether the machine is situated in, or is approaching, a critical area.
