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.
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.
The first LR 13000 was purchased by Mammoet in 2012.
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 and has a maximum pulley height of . This is achieved with the attachment of an additional lattice jib to the main boom. The height of the crawler chassis is an additional , which gives the lattice structure a total height of . The maximum hoisting height is and the total ballast used is , including of derrick ballast.
The LR series includes multiple models covering a wide capacity range:
Actual performance values depend on crane configuration, boom and jib combinations, counterweight arrangement, load radius, and ground conditions.
