Hybrid Power Booster Liebherr Pactronic®

The Liebherr Pactronic® is a revolutionary hydraulic hybrid drive system. It is characterized by an energy storage device. A hydraulic accumulator supplements the fluid pump in delivering power to the system. It serves as a pressure storage reservoir incorporating a gas in conjunction with a hydraulic fluid. Energy is stored in this compressed gas to be released upon demand. The Liebherr Pactronic® is also an impressive power-booster. Hoisting as well as lowering speeds are increased substantially - without the need to go for a bigger diesel engine with more output and emissions. Thus the crane’s...

Conventional Drive System The conventional, hydrostatic hoist system of a Liebherr mobile harbour crane is driven by a hydraulic motor, a pump, the splitter gear box and the prime mover (diesel motor or electric motor). Hydrostatic power transmission Pactronic® – Lowering Mode With Pactronic® a secondary energy source is added to the drive system. Charging of the accumulator is done by regenerating the reverse power while lowering the load. In addition, the surplus power of the primary energy source is also used for charging. Pactronic® – Hoisting Mode The stored energy of the accumulator is...
