LHM Mobile Harbour Cranes

1 Product Range 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. 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...

Structure Overview Liebherr mobile harbour cranes use the most advanced design, engineering and production technology and consist of the following main constructional groups: Optimized boom lengths (for practical applications) Closed tower design (with weatherproof access to tower cab) Tension lufﬁng cylinder (for more safety during operation) Tower extension 4.8 m (for higher boom fulcrum point and cabin height, optional) PACTRONIC® (hybrid drive system) Winches (application-oriented conﬁgurations) Undercarriage (with integrated diesel tank and additional access in middle section)...

3 Modularity Redefined 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 replaced 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...

4 Applications 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. 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...

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. • During grab operation, hoisting, slewing, and luffing are driven simultaneously at maximized speed to achieve the highest...

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...

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 LPS 280 Vanino Commercial Sea Port In its ﬂoating crane concept, Liebherr combines state of the art technology and over 30 years of experience in the mobile harbour crane ﬁeld...

Undercarriage -O The Ultimate Travelling System 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...

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. • Especially at narrow quays and terminals the...

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
