1Profitability

For many years the main advantages of the Liebherr crawler crane series are economical transport, quick and easy assembly and low operating costs as well as high flexi­ bility resulting from the consistent modular design principle, which enables the efficient use of the same parts for more than one type of machine.

2Efficiency

The high flexibility of the solid boom system allows the crane to fulfil specific requirements on site and to quickly adapt to any necessary changes. The Liebherr Litronic control system based on CAN-Bus technology offers efficient control of all functions including online load chart calculation.

3Operating comfort and safety

The ergonomic cabin design provides the operator with an unobstruc­ ted view of the entire working area. Even the standard equipment of the Liebherr crawler crane series includes numerous innovative technical features ensuring ease of operation.

4 Reliable service

With minimal product maintenance requirements, the possibility of remote diagnoses, quick assembly on site and a reliable spare parts supply, Liebherr guarantees permanent availability of its crawler cranes. LiDAT, Liebherr‘s compre-

hensive machine park management, is a data transmission and positioning system, which optimizes service.* Modern repair and training centres as well as a comprehensive network of

service stations ensure worldwide customer service. * available in selected countries

1Profitability

For Liebherr, profitability and customer benefit begin with the transportation of the crawler cranes. Prerequisites for problem-free transportation on all roads are the ideal weight and the compactness of single components. This means maximum savings in time and money even before the cranes go into operation on site.

Self-assembly system is the name of Liebherr’s advanced design, which reduces loading and assembly work to a minimum. Time and money required for these tasks can be kept to a minimum since there is no need for the usual auxiliary crane.

Profitability is also of great importance during the operation of Liebherr’s crawler cranes. The focus is on reliable and economical operation for the customer. This is guaranteed through robust and durable components, low fuel consumption and minimal product maintenance. These features are provided by robust and durable components, low fuel consumption and low maintenance requirements. This applies not only to the powerful Liebherr diesel engine, but also to all other components.

Efficient transport

Weight-optimized construction and compact design distinguish the components of Liebherr crawler cranes. Both of these basic features – low transport weight and low dimensions – enable Liebherr to guarantee quick and economical transportation to the site. All equipment can be transported on standard trucks and many crane parts are designed to fit into standard containers.

Furthermore, the transport volume is reduced by placing the luffing jib sections into the main boom sections on easy-slide pads, and thanks to their low height, counterweight pieces can be placed below the boom sections for transportation. Specially designed brackets allow storage of the pendants and pins on the boom sections.

Quick and easy self-assembly

Liebherr’s self-assembly system enables quick, easy and above all safe assembly of the cranes. Self-assembly starts with the unloading of the basic machine. The Liebherr crawler crane raises itself using four hydraulic jacks (Jack-Up System) onto solid support plates allowing the low loader to simply drive away from beneath the raised uppercarriage. Subsequently the uppercarriage unloads the side frames, counterweights and boom sections using either its A-frame or boom foot, depending on the type of crawler crane. Thanks to the sophisticated design the assembly of the side frames and the carbody counterweight is much easier using the self-as- sembly system than using an auxiliary crane. It is possible to carry out all work concerning assembly and change of equipment without an auxiliary crane. In addition, hydraulically activated pins, quick connections and an auxiliary winch for reeving of the hoist rope both facilitate and accelerate the assembly process. All boom configurations offered by Liebherr can be erected by the cranes themselves. All exactly dimensioned rigging material provided is a prerequisite to make this process and the remaining assembly so efficient.
