New Liebherr crane bears higher loads

August 2015

Liebherr has unveiled the LR 1500 that delivers the load capacities of the 500-tonne crawler crane class throughout its complete operating range, whilst upholding the dimensions and component weights, which have previously been standard in the 400-tonne class.

The overall concept of the new crane is designed for simplicity in all areas and great economy, a Liebherr statement said.

With a maximum transport weight of 45 tonnes the new crane can be transported on all markets without any restrictions. The central crawler section with turntable weighs 55 tonnes. The removable A frame allows this weight to be reduced to 45 tonnes. A quick connection is not required. The transport dimensions of 3 m in width correspond to the global transport standard.

The track width of the LR 1500 also confirms the new crane’s compact dimensions since it is in the range of 400-tonne models at just 7.6 m. The standard base plates on the LR 1500 measure 1.5 m in width. They are wider than the base plates on 400-tonne class crawler cranes. This is a great benefit as this reduces ground pressure drastically.

The travel drives on the new LR 1500 have plenty of power. They have been taken from the LR 1600/2.

The engine develops 350 kW, which is around the same level as engines on 600-tonne class cranes.

The six-cylinder inline engine used on the LR 1500 meets the emissions regulations of Stage IV / Tier 4f.

The new 500-tonne crawler crane from Liebherr delivers enormous hoist heights since the 84 m luffing jib can be installed on a main boom up to 84 m in length. The 250-tonne jib head on the luffing jib is also used for SL main boom operation. A 400-tonne head is available as standard for the S main boom for heavyweight jobs. This has the advantage of being more lightweight than the optional 500-tonne head.
