Through many years of experience and technology strictly orientated towards customer requirements, a range of
products has been created which sets new standards in innovation, quality, mobility and flexibility.
Product Range
The LHM’s extreme flexibility makes it a universal allrounder and key asset for handling everything, from containers to bulk goods, general cargo and even heavy lifts
up to 208 tonnes. Short delivery times, comparatively
low costs for transport and erection as well as minimised
operating and maintenance costs favour the LHM. It can
be used in practically all areas of the harbour where crane
capacity is required. Comprehensive basic equipment
and easy transportation guarantee a high resale value
and underline its flexibility as an investment.

The Liebherr mobile harbour crane concept as a whole is characterized by an outstanding
modularity regarding customer and port requirements.
The undercarriage is a patented Liebherr mobile
harbour crane chassis where the number
of individually mounted sets of four wheels
each can be easily adapted to comply with
the most stringent quay load restrictions.
Alterna-tively, the basic undercarriage concept can be re placed by a portal or a barge.
Different applications call for different configurations of winches and drive systems
(power packs) to conform to all variants
of professional cargo handling.
Tower extension, boom variants with
different radii and increased lifting
capacity on request (S-version) complement the modular concept of the
Liebherr mobile harbour crane.

The range of Liebherr mobile harbour cranes is suited exactly to the demands of the ship, port and transport
industries. Liebherr offers an optimum solution for every type of vessel, for every cargo and every size of port or
stevedore.
Applications
Container Handling
Due to strikingly short acceleration times of all crane
motions, which are precisely and accurately monitored
by the Litronic® control system, Liebherr emphasize their
peak position in container handling. The outreach and
load capacity are suitable to be used on a wide array of
vessels, from coaster vessels to super post-panamax
container liners.
The crane can be fitted with various types of spreaders
(fixed or telescopic) connected to the rotator. Manual,
semi or fully automatic telescopic spreaders are available
for all regular container sizes between 10’ and 48’.

Bulk Handling
The optimised interaction between powerful hydrostatic transmission and advanced Liebherr electronics ensures short,
productive working cycles in bulk handling. Independent of whether using a motor grab or a four-rope grab, all important
handling parameters such as the volume to be lifted with each grab, the opening/closing and hoisting speeds, simultaneous functions, winch synchronisation etc. are optimized using specially developed Liebherr electronics.
