The newest addition to Liebherr crawler crane models is Liebherr LR 11000, a crawler crane with incredibly high lifting and loading capacities. The LR 11000 is available with a variety of boom versions, but the most popular are the new PowerBoom parallel boom system and Derrick system. With maximum lifting capacity of 1,000 tonnes at 11m and 641 kW, Liebherr LR 11000 is able to operate very cost-efficiently in all kinds of environments, including constructed areas. Its dimensions and weights have been optimized and its design is more compact, so that it will be transported at affordable costs. As a prove, the first operation of this crawler crane has been a pure success.
For the first time since its introduction, the Liebherr LR 11000 has been employed in a refinery in the capital of Romania in July, 2014. The job in the Romanian refinery has tested all the features of the new product by Liebherr. Not only that it proved its cost-efficient transportation, Liebherr LR 11000 confirmed its ability to operate in the narrows refinery site, thanks to its compact design. The crawler crane by Liebherr has lifted about 335 tonnes using a hook with height of 80 m. As most Liebherr crawler crane models, this one is also able to deal with the most difficult conditions on a job site.
One weak point of the Liebherr LR 11000 is that the erection of luffing jib and lattice boom is difficult. Unlike the other Liebherr crawler crane models, the crane erection of LR 11000 has a new bolting section, as the slewing ring and bottom section of the slewing platform are connected to the slewing platform with only four bolts. However, when erected, the radius is reduced and the crawler crane requires a working area of about 35 meters. The main boom can extend from 24 m to 156 m and additionally extended with a lattice jib of 18 m to 114 m. For proper and stable operation, the crane requires counterweights of 790 tonnes.
Incredible construction, handling and hoist capacity, Liebherr has built the LR 11000 to perfection. For heavy-duty applications, there might be many cranes that would hoist efficiently, but there would be probably not enough space for them. For its hoisting capacity, the Liebherr LR 11000 is very compact and it is definitely its biggest advantage over all other crawler cranes. Flawless concept and design, high-safety standards and cost-efficient to transport and install, Liebherr LR 1100 is a result of the extensive experience with Liebherr crawler cranes models of the company.
