LHM Mobile Harbour Cranes

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 all-rounder 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...

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 t Closed tower design (with weatherproof access to tower cab) (for higher boom fulcrum point and cabin height, optional) (for increased lifting capacity, optional) (with integrated diesel tank middle section) Tension luffing cylinder (for more safety during operation) (application-oriented configurations) (diesel engines with different ratings depending on purpose Slewing Platform Reinforced Plastic)...

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 con- tainer 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....

Bulk Handling The optimised interaction between powerful hydrostatic trans- mission and advanced Liebherr electronics ensures short, pro- ductive working cycles in bulk handling. Independent of wheth- er 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 devel- oped Liebherr electronics. • During grab operation, hoisting, slewing, and luffing are driven simultaneously at maximized speed to achieve the highest...

Project Cargo & Heavy Duty General Cargo 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 reac- tion 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...

Practical Solutions Liebherr develops and produces special designs and solutions to meet particular requirements outside the norm, supplemented by a wide variety of lifting appliances The Liebherr Portal Crane LPS is an ef- ficient combination of space-saving por- tal 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 indivi- dually adapted. Particularly on narrow quays, individual portal solutions permit railway trains and road trucks to travel below the...

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 cabin on the slewing...

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 overload- ing of the individual wheel sets and of the quay structure. The operational position of the crane can be adapted to the quay requirements on the basis of an X-shaped stabiliser arrange- ment (quadratic and rectangular support is possible) and dif- ferent sizes of supporting pads depending...

Slewing Platform The slewing platform is designed to house the diesel-hydraulic power pack, the winches, the counterweight, the slewing gears and the electric control cabinet. Machinery House The front part of the slewing platform contains the diesel-hy- draulic power pack. This machinery house is sound insulated and fully protected against any kind of corrosion using Glass- Fibre Reinforced Plastic (GFRP). Winch Frame The winches are located within the rear part of the slewing plat- form. Various winches are available according to crane variants Middle Section The middle part of the slewing...

Electric Switch Compartment Cooling & Ventilation System Situated on the right side of the slewing platform is the electric switch compartment, containing the in-house designed Liebherr Litronic® crane control system (VME-CAN-Bus 2-line). • Availability of spare parts: 25 years • All upgrades are downward compatible • Ease of maintenance - no additional software specialist • Suitable for corrosive environment (special coating of all cards, saltspray tested) • Designed and tested for maritime environment (military • Spacious arrangement for optimal service accessibility The cooling system for...
