Liebherr is set to unveil a new 800-tonne crawler crane to visitors from all over the world at its 2018 customer days – the LR 1800-1.0. Outstanding lifting capacities and low cost transport around the world are the main features of the new large crane. It has been designed as a particularly powerful industrial crane for jobs with a luffing jib and derrick system, for example for power plant construction and the petrochemicals industry. For the first time the boom system features lattice sections with three system dimensions which can be telescoped into each other for transport.
The new LR 1800-1.0 extends the Liebherr range of crawler cranes in the class below 1000 tonnes, particularly for industrial work such as power plant construction and jobs in the petrochemicals industry.
The concept of the boom system is completely new – three lattice sections are telescoped for transport. This principle has been designed and improved for the standard configuration with an 84-metre main boom and 84-metre luffing jib. The large lattice sections are at the bottom section of the main boom, the medium ones in the top section of the main boom and in the bottom section of the luffing jib. The small lattice sections are installed in the upper section of the luffing jib. The standard length can be extended to the maximum length of the boom system of 102 metres for the main boom plus 102 metres for the luffing jib.
Another feature which reduces transport costs is that the basic machine is designed with a 3 metre transport width and a maximum transport weight of 45 tonnes. The weight of the crawler travel gear of 60 tonnes can be reduced to a transport weight of less than 45 tonnes by removing the tracks. The base plates have a standard width of 2 metres to keep the ground pressure as low as possible.
