Las Vegas (USA), 13 September 2021 - High safety levels in every respect were the main priority for the design of the Liebherr LRT 1090-2.1 rough-terrain crane. It features an outrigger monitoring system as standard. The support status, on tyres or outriggers, is detected automatically and saved to the crane controller. The attachment of the ballast to the turntable and the installation of the optional double folding jib including its angle adjustment are also recorded and monitored.
The VarioBase® variable support base developed by Liebherr, and fitted as standard on the LRT 1090-2.1, 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 when hoisting loads. VarioBase® also provides greater flexibility on site. As a result of the increased lifting capacities when hoisting over the supports, the crane can hoist loads normally reserved for the next size crane class.
Safety is also enhanced by providing greater comfort for the crane operator. For example, the crane cabin is 220 mm / 8.5" wider than other standard cabins on the market. It can be tilted backwards to provide greater comfort when hoisting loads to great heights. Clear, self-explanatory controls make the crane easy to handle. They allow the crane operator to focus on the task at hand: working with the crane and the load. A cooler and USB charging socket are standard features in the cabin.
Ladders, a large number of handles, and an electrically extending platform on the cabin, ensure safe access to the crane. The LRT 1090-2.1 features a wide range of storage boxes for accessories, rigging equipment, and support timber as standard. There is also a storage facility for the crane hook.
