Professional bulk handling – Turnover up to 550 t per hour
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 lifetime 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
compensates 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
®
teach-in
feature, a semi-automatic system, which pilots
including
the crane from the vessel hatch to the quay without any
sway. Especially for bulk operation into hoppers, the teach-
®
system increases turnover and ensures consistent
in
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.

General cargo up to 42 tonnes
The LHM displays its unique versatility and flexibility especially in general cargo handling with continuously changing
operating appliances and handling methods.
• Changing from one lifting device to another requires only
minutes.
• Special controls & individually pre-selectable lifting methods
– no modification delay.
• Automatic recognition and pre-selection of the lifting device
through Liebherr Litronic
®
control system.
• The hydrostatic drive concept in connection with closed
hydraulic circuits guarantees immediate system reaction
times for rapid and safe working cycles.
• The luffing cylinder also uses a closed hydraulic circuit,
assuring accuracy without vibration.

Mobility
• Outstanding mobility and manoeuvrability
• Curves at any possible radii and even slewing
on the spot
longitudinally
diagonally
Modular propping system
• Minimised stress and strain of undercarriage due to cruciform support
base which directs the load path from boom tip to quay
• Modular system allows further reduction of quay loads by installing
additional axle sets
• Easy adaptation to various sizes of support pads and bases
Optional wheel sets

Hydraulic load distribution
• Hydraulic suspension avoids overloading of individual wheel sets
Standard trailer tyres making requisition of spares economical and
time-saving
Increased lifetime of tyres due to individually steerable wheel sets

Practical solutions
Liebherr develops and produces special designs and solutions to meet
customer-specific requirements
• The Liebherr Portal Crane, LPS, is an efficient combination
of a space-saving portal (mounted on rails) and the proven
mobile harbour crane concept. Particularly on narrow quays,
individual portal solutions permit (railway) trains and (road)
trucks to travel below the portal.

• Liebherr Fixed Slewing Cranes (LFS) are an efficient
combination of a mobile harbour crane upper carriage and a
fixed pedestal. LFS cranes provide an economical and spacesaving solution for the installation on quaysides and jetties,
especially where room for manoeuvring is limited and low
ground pressure is essential.
