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%

Liebherr Pactronic pressure accumulator – 100% recyclable
The pressure reservoir is a means of storing energy and is based on trusted technology. The Pactronic accumulator from Liebherr combines these advantages.
- Visual inspection every 10 years sufficient
- All components are extremely robust
- Has the same service life as the crane
- Fast loading and unloading times
- 100% recyclable

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

Pactronic hybrid drive for the HS 8300 HD Hybrid
The new HS 8300 HD duty-cycle crawler crane is the first device from the construction machine sector equipped with the innovative Pactronic hybrid drive. The hydraulics-based drive system offers both economic and ecological benefits. Excess energy is stored and then reactivated. In this way, the handling performance is increased while reducing fuel consumption at the same time.
Advantages of hybrid drive
- 725 kW diesel engine enables hook performance of 800 kW as well as a system performance that with 1,250 kW is comparable with a conventional drive system.
- Greater handling volume thanks to improved lifting and improved lowering
- Reduced fuel consumption and in turn lower CO2 emissions
- Lower noise emissions
- Trusted technology from the Liebherr mobile harbour crane series
- Revolutionary hydraulic hybrid drive – significant increase in lifting and lowering speed
- Reduction in maintenance costs
