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 at
1900 rpm, max. torque 815 Nm at 1500 rpm, 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
• Comfortable armrest control with 2 self centering 4-fold multi function joysticks,
stepless control of all crane movements with winch and slewing turning sensors,
electronic pilot control
• 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
