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 drive from diesel engine in chassis
• 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 controls with 2 self-centering 4-fold multifunctional joysticks,
stepless control of all crane motions, with winch and slewing gear indicators
• Slewing gear standard 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
