SIKU 1:87 Mobile Heavy Lift Crane: Liebherr Group

A mobile crane is a cable-controlled crane mounted on crawlers or rubber-tired carriers or a hydraulic-powered crane with a telescoping boom mounted on truck-type carriers or as self-propelled models.They are designed to easily transport to a site and use with different types of load and cargo with little or no setup or assembly.

Mobile cranes generally operate a boom from the end of which a hook is suspended by wire rope and sheaves. The wire ropes are operated by whatever prime movers the designers have available, operating through a variety of transmissions. Steam engines, electric motors, and internal combustion engines (IC) have all been used. Older cranes' transmissions tended to be clutches. This was later modified when using IC engines to match the steam engines' "max torque at zero speed" characteristic by the addition of a hydrokinetic element culminating in controlled torque converters. The operational advantages of this arrangement can now be achieved by electronic control of hydrostatic drives, which for size and other considerations is becoming standard. Some examples of this type of crane can be converted to a demolition crane by adding a demolition ball, or to an earthmover by adding a clamshell bucket or a dragline and scoop, although design details can limit their effectiveness.

The Liebherr Group is a multinational equipment manufacturer based in Switzerland with its main production facilities and origins in Germany.

It consists of over 130 companies organized into eleven Divisions: Earthmoving, Mining, Mobile cranes, Tower cranes, Concrete technology, Maritime cranes, Aerospace and transportation systems, Machine tools and automation systems, Domestic appliances, and Components. It has a worldwide workforce of over 42,000, with 9 billion euros in revenue for 2017. By 2007, it was the world's largest crane company. Established in 1949 by Hans Liebherr in Kirchdorf an der Iller, Baden-Württemberg, Germany, the business is still entirely owned by the Liebherr family. Isolde (daughter of Hans) and Willi (son of Hans) Liebherr are the chief executive and chairman of the Bulle, Switzerland-based Liebherr-International AG, and several other family members are actively involved in corporate management.

In 2005, Forbes magazine listed them as billionaires. In 1974, the Franklin Institute awarded Hans Liebherr the Frank P. Brown Medal.

Starting by building affordable tower cranes, Liebherr expanded into making aircraft parts – it is a significant supplier to European Airbus airplane manufacturer – and commercial chiller displays and freezers, as well as domestic refrigerators. The group also produces some of the world's biggest mining and digging machinery, including loaders, excavators and extreme-size dump trucks. The T 282 B is the world's 2nd biggest truck (after BelAZ 75710). The group's nine-axle mobile crane, the LTM 11200-9.1 – with a 100 metres (328 ft) telescopic boom – in 2007 received the heavy-lifting industry's Development of the Year award for being the world's most powerful example of such a machine.
