Some customers liked the pin- and latch-style with higher load charts, while others preferred a full-power hydraulic boom with higher speed. The 110-ton LRT 1100-2.1 RT crane features a 164-ft.-long, five-section telescopic boom with the Telematik single-cylinder telescoping system that pushes out the boom sections independently with a single cylinder and pins it to the telescopic section above. “As the entire counterweight consists of one slab only, chances of an incorrect ballast arrangement are virtually impossible,” says Ulrich Hamme, managing director, construction and development for Liebherr-Werk Ehingen.
Operating the Telematik was simplified for operators, and only two telescopic modes—strong and long— are offered. The single-piece, 15.4-ton counterweight can be assembled and disassembled with a hydraulic ballasting cylinder, which is installed inside the front of the chassis and will be standard for the U. The 100-ton LRT 1090-2.1 has a 154-ft.-long telescopic boom, and its full-power boom consists of a two-stage hydraulic cylinder and a rope extension system, similar to Liebherr’s smaller LTM all-terrain cranes.
With the attention placed on growing these offerings, the company discontinued its LTL rough-terrain crane production, of which it had built about 430 machines in the 25- to 80-tonne range.
Today, the company offers 38 different cranes in its LTM and LR product lines.
The total weight of the crane was 121,000 lbs., and it measured 12’8” tall and 10’10” wide.
