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.

Project Cargo and Heavy Duty

Safety and precision are the most important criteria when
lifting heavy goods. The hydrostatic drive concept in con­nection with closed hydraulic circuits guarantees imme­diate system reaction times for rapid and safe working
cycles.
Depending on the type, Liebherr mobile harbour cranes
can lift up to a maximum of 208 tonnes. The endurance
and stability required especially for this kind of cargo han­dling has been strongly considered as a basic concept.
The unique Liebherr cruciform support base creates sta­bility. The arising forces are diverted to the surface of the
pier via the shortest routes.

LPS

The Liebherr Portal Crane LPS is an efficient combi­nation of space-saving portal undercarriage (mounted
on rails) and a flexible mobile harbour upper carriage.
Customer-specific requirements such as permissible
quay and rail loadings, track gauges, clearance heights
are individually adapted.
Particularly on narrow quays, individual portal solutions
permit railway trains and road trucks to travel below the
portal.

LBS

In its floating crane concept, Liebherr combines state
of the art technology and over 30 years of experience
in the mobile harbour crane field with the expertise of
established barge manufacturers.
Liebherr floating cranes can be used for transhipment
and midstream operation between ocean-going ves­sels and river barges on different types of waterways,
including those having no or few quays. In addition, the
LBS solution allows direct cargo transfer from ship to
shore; especially when quays have reached capacity
limits.
This floating crane concept, based on many years of
experience in designing and operating floating cranes
and other transhipment units for various environmental
conditions throughout the world, is conceived for mid­stream operation in ports and sheltered waters, on riv­ers and in coastal waters; for ship to ship as well as ship
to shore handling. Based on the Liebherr mobile har­bour crane series, the LBS models are precisely tailored
to meet individual requirements and manufactured ac­cording to a uniform design principle combined with
purpose-built barges as customer specific solutions.

Undercarriage –

6

Varying design and construction methods of quays and terminals throughout the world have led Liebherr to a
unique undercarriage design. Having turned away from a fixed axle concept, individually mounted sets of four
wheels each enable movement in all directions.

Individual Wheel Sets

During steering operation all driven wheel sets are indi­vidually controlled and steerable. At every wheel set a
sensor indicates the actual wheel position to the elec­tronic control system. The steering can be operated ei­ther from the tower cabin or the operator’s cabin on the
slewing platform.

Outstanding Mobility

Liebherr mobile harbour cranes are characterised by
their outstanding mobility. Due to the system of inde­pendent and individually steerable wheel sets (no ad­ditional infrastructure e.g. rails or power supply are re­quired) and a very short undercarriage not only are the
smallest turning circles possible but also longitudinal
and diagonal movements of up to 135°. The LHM can
travel in all directions, whether straight ahead, back­wards, sideways diagonally or even turn around variable
centre points, knowing no limits.

Hydraulic Load Distribution

The modular undercarriage concept allows further re­duction of quay loads by installing additional wheel sets
to comply with the most stringent quay load restrictions.
During travelling hydraulic suspension guarantees op­timum pressure distribution on uneven ground and
avoids overloading of the individual wheel sets and of
the quay structure.

Independent linked suspension causes lower loads onto quay structure

Liebherr undercarriage – optimal accessibility from every direction

18

X-shaped Support Base

The operational position of the crane can be adapted
to the quay requirements on the basis of an X-shaped
stabiliser arrangement (quadratic and rectangular sup­port is possible) and different sizes of supporting pads
depending on the condition of the quay. A special
Liebherr feature is the very solid propping system with
four swing-out arms forming a cruciform propping con­figuration. Stresses and strains occurring during han­dling operation are thereby transmitted via the shortest
route through the centre of the chassis onto the outrig­gers and further to the ground.

A Liebherr triple row roller bearing connects the slew­ing platform with the undercarriage allowing for unlim­ited rotation in both directions. Slewing gear units are
placed around the slew-ring bearing according to crane
variants and application. Due to the round tower design
the load is already distributed over 360 degrees when
it arrives at the slew-ring resulting in longer life time of
components as well as the steel structure.

Cooling and Ventilation System

The cooling system for the engine water and the engine
charge as well as the hydraulic oil cooler are situated
outside on top of the slewing platform (for working con­ditions above 50°C). The cooling air flow is completely
conducted outside the machinery room: for such rea­son it is not possible to contaminate the diesel engine
and other hydraulic components with dust particles.
In addition Liebherr technology is absolutely insuscepti­ble to all sorts of dust and dirt due to the closed hydrau­lic system and an electronic system which is military
proven and tested.

Drive Concept - Advantages Of Liebherr Hydrostatic Power Transmission

The Liebherr hydrostatic drive is undeniably the most
reliable and high performing drive system for every mo­bile harbour crane due to rapid achievement of high per­formance, long-term durability, low maintenance costs
and a series of operation-specific advantages such as
outstanding acceleration and deceleration. This means
higher turnover in shorter periods and proven savings
for the customer.

The crane drive is diesel-hydraulic consisting of a split­ter gear box feeding variable displacement axial piston
pumps for the hoisting, slewing and the luffing gear. In
an effort to reduce complexity, during travelling pumps
from other operations are used. The splitter gear box
can either be driven by a diesel motor or alternatively by
electric motors.
Closed hydraulic circuits technology for maximum per­formance and high efficiency is used. The independent,
closed circuits guarantee a highly responsive, smooth
and sensitive operation with a minimum of components,
maximising the operating safety even in continuous op­eration or high ambient temperatures (-40°C to +50°C).

Tower and Boom

Tubular Tower Design

The submerged-arc welded pipe construction, a torsion­ally rigid design, is part of a unique stress-flow system
absorbing all static and dynamic demands and distribut­ing the load as best as possible onto the slew ring bear­ing. The spiral staircase is well lit with handrails and kick­plates, leading to the tower cabin. Access to the upper
tower platform and rope pulleys is also gained through
this route.

The tower and optional slewing platform cabin are fully equipped allowing the operation of all crane functions includ­ing travel and supporting options. The design of the tower and the slewing platform cabin was driven by the needs for
visibility, comfort and operability.

Driver Comfort

Tower Cabin

The crane operator’s cabin layout has been designed to
ergonomic principles and provides a comfortable, noise­free environment, essential for ensuring uninterrupted
concentration for the driver when operating the crane.
Any vibration is reduced to an unnoticeable minimum
through active swing equalisers.
An ergonomic driver‘s seat with adjustable armrests,
screen wipers and washer as well as air conditioning
allow the operator to work in all climatic environments.
Control desk, joy-sticks and monitor are ergonomically
arranged.
The window sections are constructed of tinted anti glare
toughened safety glass mounted in an innovative glass
frame design giving a clear view of the handled cargo
throughout the slewing circle and an unobstructed line of
sight between the boom tip and the vessel deck.

With its headquarters located in an environmentally protected area, ecological issues have always been high on the
agenda for Liebherr-Werk Nenzing. The implementation of economy software, bio-degradable oils and special noise
insulation throughout its mobile harbour crane range are just a few examples of Liebherr’s ecological awareness.

Environmental Record

Eco-Control

The proven hydraulic drive system in combination with the
in-house developed “ECO-Control” achieves a notable
reduction of diesel consumption up to 25 % without any
impact on turn-over output. Once the designated speed of
the crane movement is achieved, the Litronic® crane con­trol system automatically calculates the minimal required
rpm (revolutions per minute) for the diesel engine.
A further side effect is the low rpm of the hydraulic system,
which means longer lifetime of hydraulic pumps and com­ponents. In addition, the lowered engine rpm has a direct
impact on reduction of noise exposure.

Operating Liquids

Alternatively Liebherr mobile harbour cranes can be run
on bio-diesel to comply with local regulations and the
transition to alternative fuels in customer equipment fleets.
Liebherr developed biodegradable oil especially for
the Liebherr product line. In combination with spectro­graphic oils analysis techniques oil life time is extended
and keeps components such as pumps and motors for
ever longer lifetimes.
Due to the special design of the luffing gear (tension
cylinder in closed loop circuit) a minimal quantity of oil is
required.

Noise Insulation

The cooling system for the engine water and the engine
charge as well as the hydraulic oil cooler are equipped with
a specially designed cooling fan minimizing turbulences
and decreasing noise emissions. Furthermore, regulated
rpm guarantees higher lifetime, less required drive power
and a decrease of fuel consumption.
Elastic suspension of the winches guarantees an additional
reduction of vibrations and noise. With the optional attenu­ation package for the machinery as well as the winch room
a further reduction of sound pressure can be reached.

Liebherr-MCCtec Rostock

In order to further expand its position in the international
maritime market Liebherr has established an additional
production site for mobile harbour cranes in Rostock’s
harbour district on the German Baltic Coast in 2006.
The production facility in Rostock plays an important role
in the further growth and development of the international
market position of the LHM product division. Overall, the
Liebherr Group has four state-of-the-art production sites
for maritime cranes (Nenzing, Rostock, Killarney and
Sunderland).

Factory Testing

All LHM cranes are put through an intense factory testing
program, this means that every single crane is fully as­sembled and tested before delivery which results in an ex­traordinary quick commissioning. Under normal conditions
Liebherr mobile harbour cranes are assembled and ready
for operation within two weeks after delivery.

Fully Assembled Transportation

Thanks to direct access to the sea, Rostock is very well
situated in terms of the logistics of worldwide sales, espe­cially when shipping large equipment. Ro-Ro shipment,

The Liebherr Group –
Partner For The Future

Today, Liebherr is among the leading manufacturers in the fields of hoisting technology and materials handling equip­ment. The name Liebherr stands for products and services. It has become a synonym for ideas and innovations.

Liebherr – A Family Enterprise

In family-operated companies, ownership merges with
active entrepreneurship. This results in characteristic
principles. Liebherr is both a family business and a cor­poration. This does not have to be a contradiction, as the
continuous success and steady growth prove.
To create top products, the development capacities and
production facilities must measure up to the highest
standards. This requires substantial investments. From
stable locations, Liebherr is following a solidly financed
expansion course. The profits made are almost entirely

retained within the Group. This provides ample scope
for extensive investments. The economic power of the
Liebherr Group is best shown by its unusually high equity
ratio of more than 50%. This sound economic basis
makes Liebherr highly independent in its strategic deci­sions, and it provides an important basis for future invest­ment and innovation strategies. Offering high-quality
products and services which are aimed towards custom­ers’ needs remains the benchmark.

34

Mastering Key Technologies

In

view of the high quality that Liebherr demands of its
products, mastering key technologies internally and keep­ing core competencies in-house has always been of great
importance to the company. Therefore, Liebherr develops
and produces crucial components, such as the entire
propulsion and control technology, themselves. Further
examples are hydraulic components, slip ring elements,
and diesel engines. Here, Group suppliers are measured
against the best and most efficient external providers.

Decentralized And International,
Based On Tradition

Operating efficiently in manageable, self-dependent
units and aimin
always formed part of the basic business principles. Thus,
Liebherr regularly invests substantially in further market­ing and service companies as well as in new production
sites. Entering and expanding into new markets means
being locally available to assure the customer receives full
and lasting manufacturer support.
