New Liebherr Crawler Crane Lifts 110 USt, Raises 209’ of Boom and Jib
April 3, 2022 – Liebherr’s new LR 1100.1 crawler crane is optimized for all typical lifting applications in the 110-USt class.
It can be configured either with a boom up to 203.4’, or with a boom of up to 144.3’ plus a fixed jib of up to 65.6’.
The LR 1100.1’s 308-hp (230-kW) engine is the most powerful in this capacity class.
Thanks to Eco-Silent Mode, the engine speed can be reduced to a predefined level. That reduces fuel consumption and noise without reducing performance.
Automatic Engine-Stop Control offers even more economy and environmental friendliness. After checking system functions, the engine switches off during longer work interruptions.
Easy Transport and Setup
The crane’s design enables quick transportation between sites. The main load’s transport width is 9’9.5” with crawlers off, or 11’6” with crawlers on.
On-site assembly is quick and is simplified by the self-assembly system and radio remote control.
Radio remote control allows the crane operator a high degree of flexibility and additional safety even during operation. The crane can be operated from outside the cab to allow for a better view of the construction site. That helps avoid blind spots. Depending on the application, a second person is no longer required to assist with hand signals during lifts. The crane’s cab can be elevated by 9’3” for a good all-round view.
Safety on Slopes
For safe travel on slopes, the Gradient Travel Aid feature lets the crane’s control system automatically calculate the center of gravity and warns the operator before the crane becomes unstable. While the crane is travelling, the operator continuously receives information about the permissible and actual gradient, as well as the crane's overall center of gravity. If necessary, the operator can change the boom angle to help keep the crane balanced.
