With proven components
The drive components for the crane operation are designed for high performance
and provide for sensitive and precise handling of the load. They are specially tuned
for the crane operation and proved in severe long-term tests.
• Crane engine: 4-cylinder Liebherr turbo diesel engine, 129 kW/175 HP, max.
torque 815 Nm, optimized fuel consumption by electronic engine management
• Diesel-hydraulic crane drive, open hydraulic circuits with electric „LOAD
SENSING“-control, 4 working motions simultaneously possible
• Electric/electronic SPS-crane control via the LICCON-computer system
• Slewing gear reversible from open to hydraulically locked, so the slewing motion
can be optimal adapted for the different operation conditions, e. g. sensitive for
installation work or fast for cycle work
• In-house fabricated Liebherr winches, 77 kN rope pull at the outer layer, less
reeving necessary due to high line pull
Powerful crane drive
The slewing gear
• Liebherr planetary gearbox, spring loaded
multi disk brake
• Reversible open or hydraulically locked as
standard
• Slewing speed from 0 – 1.7 rpm infinitively
variable
The central greasing
• Standard central greasing device for
slewing bearing, boom bearing, luff-
ing cylinder and winch bearing
• Even supply of grease
• Filling quantity visible at any time in
transparent reservoir
