Liebherr has set a new world record by putting together a crawler crane with a boom height of 248m, and with a 3,000-tonne rated capacity, the LR 13000 is also the world's strongest conventional crawler crane.

The combination of the 120m main boom and the 126m luffing jib produces a lattice boom system with an overall length of 246m. Mounted on itsa crawler chassis, the crane rises to a height of 248m.

Following its assembly at the Liebherr crane factory in Ehingen, Germany, the crane's function was then confirmed by engineers, who tested the stability of the boom system with a load of 103 tonnes.

With its maximum boom length at its steepest angle its load capacity is 68 tonnes.

For the world record the LR 13000 was fitted with 400 tonnes of slewing platform ballast and 1500 tonnes of derrick ballast on a special foundation.
