Pactronic hybrid drive

The Liebherr Pactronic is a revolutionary hybrid drive system. The major feature is an additional energy storage device, also known as an accumulator.

The accumulator is charged when the load is lowered and also if there is a surplus of power from the conventional drive unit. The Pactronic system from Liebherr is an impressive power booster. Both the lifting and lowering time are sped up significantly despite the primary power remaining unchanged. In addition, fuel consumption of the crane is reduced. The fuel saving is achieved through complete utilisation of the regenerative energy and surplus power in the system.

Pactronic stands for highly efficient enhancement of performance and material handling output. If additional energy is required for crane operation, the Pactronic system transfers the energy stored in the accumulator back into the system, thereby enhancing the lifting performance of the crane.

  • Twice the lifting speed +100%
  • Twice the lowering speed +100%
  • Handling performance depending on the application +30%

Pactronic achieves greater performance while reducing fuel consumption at the same time. The sustainable hybrid drive therefore reduces the emission of CO2 and other harmful substances. With Pactronic, Liebherr smooths the path towards goods handling with high efficiency and low emissions.

  • Reduced fuel consumption -20%
  • Reduced CO2 emissions -30%
  • Reduced noise
