The new HS 8300 HD is fi tted with the Pactronic ® system developed
by Liebherr. This innovative hybrid drive based on hydraulics offers
both economic and ecological advantages. Storing and subsequent
regenerating of surplus power allows to increase turnover and to
signifi cantly lower fuel consumption. The proven technology of the
hydraulic accumulator ensures low maintenance requirements and
maximum reliability. The decreased energy consumption considerably
lowers emissions and thus improves environmental compatibility.
Powerful, energy-effi cient hybrid drive
• A secondary energy source is added to the drive system.
• The accumulator is charged by regenerating the reverse power while
lowering the load.
• The additional surplus power of the primary energy source is used
for charging.
Pactronic ® - Lowering mode
• 725 kW diesel engine combined with Pactronic® allows to achieve
a system power comparable to a conventional drive system with
1,250 kW
• Effective hoisting power of 800 kW
• Reduced fuel consumption resulting in less C0
2
emission
• Lower noise emission
• Increased hoisting power
• Increased lowering power
• Higher turnover with identical prime mover
Key advantages of Pactronic ®
Pactronic ® - Hoisting mode
• Stored energy is transferred to the system when the crane requires
peak power for hoisting.
• The total hoisting power is the sum of the conventional hydrostatic
power and the secondary energy from the accumulator.
