Liebherr’s new LTR 1150 telescopic crawler crane has 50% more lifting power than the company’s LTR 1100, but it can be transported just as easily as the smaller crane, the company says.
The crane, which has a 150-metric-ton lift capacity, is also the first with Liebherr’s VarioBase system, “which determines the optimum load capacity in real time depending on the fixed track width and the variable rotation angle.”
The LTR 1150 is geared toward construction sites where lifting in many places is needed, such as industrial-building construction. It can move up to 34.6 metric tons into position. And the 173-foot boom can be hydraulically extended to 272 feet with a hydraulically adjustable double-folding jib and telescopic boom extensions, the company says.
The cranes can also be used for wind turbine assembly on wind farms.
The LTR 1150 is designed to be transported by one semi-trailer, but can also be configured for lower weight and width.Liebherr
Weight can be reduced to 38 metric tons by removing the tracks and reducing the width to 9.8 feet. The tracks can be removed by jacking up the crane with four swiveling cylinders. The trailer can then be positioned under the crane. Two tracks can each be hauled on the same semi-trailer. They weigh 11 metric tons each and combined are 8.4 feet wide.
