The Liebherr LR series are crawler cranes designed and manufactured in Germany by Liebherr-Werk Ehingen GmbH, a subsidiary of the Liebherr Group.
A model in the LR series, the LR 13000 is known for being the tallest and most powerful conventional crawler crane in the world.[2][3]
History
[edit]Production and sales of Liebherr crawler cranes began when TVA in the USA purchased two LR 1300Vs. In 1978, Liebherr Ehingen delivered its first two crawler cranes.[1]
Design and enginearing
[edit]LR crawler cranes are mounted on tracked undercarriages, providing high stability and ground pressure distribution, as well as the ability to travel with suspended loads within defined limits. Depending on model and configuration, the cranes support a variety of boom systems, including main boom, luffing jib, derrick boom, and fixed jib combinations.
The LR 13000 is capable of lifting 3,000 tonnes (2,953 long tons; 3,307 short tons) and has a maximum pulley height of 248 metres (814 ft). This is achieved with the attachment of an additional 126-metre-long (413 ft) lattice jib to the 120-metre (390 ft) main boom. The height of the crawler chassis is an additional 2 m (6 ft 7 in), which gives the lattice structure a total height of 248 m (814 ft). The maximum hoisting height is 245 m (804 ft) and the total ballast used is 1,900 tonnes (1,870 long tons; 2,094 short tons), including 1,500 tonnes (1,476 long tons; 1,653 short tons) of derrick ballast.[5]
