Pactronic ®
As the cargo handling industry is evolving, so are the
needs for efficient, cost-effective cargo handling equip-
ment and increased handling performance. In addition,
no manufacturer can reject the demand for sustainable,
environmentally sensitive operation and the call for low-
emission cargo handling equipment.
Liebherr Pactronic ® stands for Power by Accumulator and
Electronics. The system is characterized by an energy
storage device, which is added to the drive system as a
secondary energy source. The Liebherr Pactronic
® hybrid
drive is an integrated approach to meeting the needs of
the industry. Charging of the accumulator is done by re-
generating the reverse power while lowering the load and
using the surplus power from the primary energy source.
This results in substantially higher hoisting and lowering
speeds. Not only is the crane’s efficiency increased but
also the turnover
(+ 30%). In addition, the crane’s fuel
consumption is significantly reduced
(- 30%). This is
achieved by fully utilizing the reverse energy and surplus
power within the system.

Reduction of total cost of ownership
Environmental Advantages:
30 % less fuel consumption
30 % less CO
2
30 % less exhaust emissions
Structural Advantages:
Designed service life is equal to that of the crane
Just visible inspection every 10 years
100 % recyclable
