Liebherr has claimed a new world record after it erected a 3,000 tonne capacity LR 13000 lattice boom crawler crane in its maximum configuration, reaching an overall height of 248 metres.

The record was set at the Liebherr manufacturing plant in Ehingen, Germany, in July 2013.

For the assembly, the crane was configured with a 120 m main boom and a 126 m luffing jib, creating a total lattice boom system height of 246 m. Added to the 2 m elevation of the boom foot in the crawler chassis, the overall height of the crawler reached 248 m. For the world record the LR 13000 was fitted with 400 tonnes of slewing platform ballast and 1,500 tonnes of derrick ballast on a special foundation, a company spokesperson added.

To assemble the crawler in this configuration the main boom was slowly raised with the assistance of the derrick winch. During this time the luffing jib was angled down and the roller cart was released; the hook block was then reeved in on a 2-line basis, a company spokesperson said. Once these stages were completed, the boom system, which weighs a total of 700 tonnes, was raised into position.

Once in position, the crane lifted a twin-axle LTM 1030-2.1 mobile crane weighing 24 tonnes.
