With tried-and-tested components
The drive components for crane operation are designed 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 drive from chassis diesel engine
• Optimised fuel consumption by electronic engine management
• Diesel-hydraulic crane drive, open hydraulic circuits with electronic
“Load Sensing” control, 4 working movements simultaneously possible
• Electric/electronic SPS crane control through the LICCON computer system
• Comfort armrest control with 2 self-centering, 4-fold multifunctional joysticks,
stepless control of all crane movements, with vibration joysticks for slewing gear
and winch operation, electronic pilot control
• Slewing system changeable from open to hydraulically locked as standard, thus
the movement can ideally be adjusted to the different operational conditions,
e. g. sensitive control for assembly work or fast cycle work
