Liebherr expands RT range with LRT 1130-2.1

Liebherr unveiled a 130-tonne rough-terrain crane at Bauma 2022 under the slogan “The toughest in the roughest.” The new LRT 1130-2.1 offers very high lifting capacities and the longest telescopic boom of any 2-axle rough-terrain crane anywhere in the world, the company said. It also has the most economical transport dimensions in its performance class.
The new Liebherr rough-terrain crane is currently the only 143-ton (130-tonne) crane on a 2-axle chassis. At the same time, its telescopic boom is the longest in its class at 197 feet (60 meters). It consists of the pivot section and six telescopic sections and is extended and bolted fully automatically with the Liebherr TELEMATIK high-speed telescopic system.
A 35-foot (10.8 meter) single folding jib or a 10.8 - 19 metre double folding jib is available for the LRT 1130-2.1. It is mounted at angles of 0°, 20° or 40°, or can optionally be hydraulically tilted from 0° to 40°. With an additional seven-metre lattice section as a telescopic extension, the new crane reaches hook heights of up to 279 feet (85 meters). The folding jib is carried on the right-hand side of the boom. At the same time, a 9.5-foot (2.9-meter) assembly jib can be attached to the left-hand side of the boom. A side-folding rooster sheave, which can be operated in 2-line mode, rounds off the boom options.
Liebherr has designed the dimensions of the new LRT 1130-2.1 so that it can be transported economically on low-loaders worldwide. Its width is 11.2 feet (3.4 meters), its height 12.6 feet (3.85 meters) and its chassis length is 30.8 feet (9.4 meters). The transport weight is 53 tons (48 tonnes) without ballast, but with the folding jib and hook block. This can be reduced to 49.4 tons (44.8 tonnes). These values are unique in the class of powerful 2-axle all-terrain cranes. A permit-free standard transport vehicle is sufficient for the 22-ton (20-tonne) ballast and additional equipment. The counterweight consists of three ballast slabs and is attached to the slewing platform via self-assembly with ballasting rams.
