loaded multi-disc brake
• Can be switched as standard:
released or hydraulically locked
• Slewing speed can be steplessly
adjusted from 0 to 1.5 rpm
Centralised lubrication
• Centralised lubrication system as
standard for slewing ring, boom
bearings, luffing ram and winch
bearings
• Uniform application of lubricant
• Lubricant level visible in transpar-
ent container at all times
High-power crane drive
With tried-and-tested components
The drive components for crane operation are constructed for high performance
and ensure sensitive and precise load handling. They are specially designed to
suit the crane’s usage and have been subjected to hard endurance tests.
• Crane engine: four-cylinder Liebherr turbo-diesel engine, 129 kW/175 hp,
920 Nm max. torque, optimised fuel consumption thanks to electronic en-
gine management
• Diesel-hydraulic crane drive, open oil circuits with electric LOAD SENSING
control, four simultaneous working motions possible
• Electric/electronic SPS crane control via LICCON computer system
• Slewing gear can be switched as standard: released or hydraulically locked.
The movement can thus be optimally adapted to the different operating
requirements, e.g. sensitive assembly work or rapid work cycles
• Self-manufactured Liebherr winches, 88 kN line pull at the outer layer, great-
er line pull means less rope reeving is needed
