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 engine: 4-cylinder Liebherr turbo diesel engine, 129 kW/175 HP, max.
torque 815 Nm, optimised fuel consumption due to 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
• Slewing system changeable from open to hydraulically locked as standard, thus
the movement can be adjusted to the different operational conditions, e. g. sen-
sitive control for assembly work or fast cycle work
• In-house manufactured Liebherr winches, 88 kN rope pull at the outer layer, due
to high rope pull less rope reeving necessary
