Liebherr has successfully tested the load-bearing capability of its LR 1800-1.0 crawler crane, which was launched by the manufacturer in mid-2018.
The LR 1800-1.0’s 84 m-long main boom, equipped with a derrick system, completed a 560-tonne test lift at a 12 m radius.
To hoist the test load, 400 tonnes of suspended ballast was extended to the maximum radius of 23 m. The crane was also equipped with 170 tonnes of ballast on the slewing platform and 70 tonnes of central ballast.
The crane consists of the powerful main boom, a derrick system, and Liebherr’s new hydraulically adjustable ballast system – the V frame.
The crane will be tested with heavier loads ahead of the bauma construction machinery exhibition, which takes place April 8-14, 2019 I Munich, Germany.
Another feature of the crane that reduces transport costs, according to Liebherr, is that the basic machine is designed with a 3 m transport width and a maximum transport weight of 45 tonnes.
The LR 1800-1.0 extends the Liebherr range of crawler cranes in the class below 1,000 tonnes, particularly for industrial work such as power plant construction and jobs in the petrochemicals industry.
