The powerful hydrostatic transmission and advanced Liebherr electronics ensure short, productive working cycles
during bulk handling.
• During grab operation, hoisting, slewing, and luffing are
driven simultaneously at maximized speed to achieve the
highest (possible) turnover.
• During grab filling, features such as automatic lowering and
hoisting guarantee the optimum filling level of the grab.
• The slack rope monitoring system ensures extended life-
time of the ropes and increases operational safety.
• Reverse power is returned to the drive process through
closed loop hydraulics which results in reduced fuel
consumption.
• The Cycoptronic ® anti-sway system automatically compen-
sates for all rotational swing, transverse and longitudinal
sway of the load at maximum speeds.
• To provide safe and stress-free working conditions for the
operator, Liebherr offers the Cycoptronic ® including Teach-
In ® feature, a semi-automatic system, which pilots the
crane from the vessel hatch to the quay without any sway.
Especially for bulk operation into hoppers, the Teach-In
®
system increases turnover and ensures consistent turnover
rates during the entire ship unloading.
• Liebherr technology is absolutely resistant to all types of
dust and dirt due to the closed hydraulic system and an
electronic system which is military proven and tested.
• The airflow needed for cooling hydraulic and engine
systems is routed external from the main machinery
house. This helps keep the engine room clean and free
of debris.
Standard configuration Turnover up to 1500 t per hour
Pactronic ® Turnover up to 2000 t per hour
