The development of new generation Liebherr rough terrain cranes was preceded by extensive market surveys and analyses into the requirements for modern RT cranes, particularly in the main market of North America. In addition to the capacity of the cranes, their safety, particularly from ease of operation, was one of the main focal points for the development of the new cranes.
The two newly designed LRT cranes are based on the same basic technical concept. The crane chassis and turntable are almost identical. The differences relate to the boom length, telescoping technology, ballast weight and lifting capacity.
High safety levels in every respect, were the main priority for the design of the new Liebherr LRT cranes. Both new crane models feature an outrigger monitoring system as standard. The VarioBase® variable support base developed by Liebherr as standard on the new LRT cranes makes an important contribution to enhancing safety. VarioBase® allows each individual outrigger beam to be extended to arbitrary lengths. The crane work is controlled by the load moment limiter within the LICCON controller which calculates the maximum load capacities precisely for the current situation. This prevents accidents by human error during the assembly process and while hoisting loads.
The new LRT cranes from Liebherr are powerful and robust, have good off-road capability and are also manoeuvrable. Both crane models are powered by a CUMMINS diesel engine which meets all current emissions regulations.
