Liebherr LR1750/2

Liebherr has released news on 3rd April 2015 that they have modified its current LR1750 crawler crane with the upgraded 750-tonne LR1750/2 model now available. By strengthening the main boom and adjusting the derrick system the crane’s load capacity has been increased in some areas by up to 30%. This means that the crane offers much better value for money.

Product Description

The LR 1750/2 crawler crane is suitable for universal use and is used in power plants, refineries, on Bridge construction sites and for erecting wind turbines. The compact dimensions of the crane components and their moderate weights mean that the crane can be transported to the site at a low cost. The 750-tonne model can also be used as a pedestal crane on supports.

The adjustment of the derrick system includes an extension of the derrick boom by 7 m to 38.5 m. As with the “H boom kit” for the LR1600/2, the strengthened boom systems on the LR1750/2 together with the derrick system has been given the suffix “H” (Heavy) which stands for powerful, heavy boom systems.

The ballast trailer has also been modified as part of the modification to the Liebherr 750-tonne crawler crane. This now has a hydraulic drive unit which means improved handling. The new LR 1750/2 also provides enhanced safety for the operating personnel since the crane has additional platforms and access points and its railings have also been extended and improved.

During its modification of the LR1750, Liebherr ensured that the existing equipment components can also be used on the new LR 1750/2. This is a major benefit for crane contractors who already operate one or more LR1750 cranes in their fleets.
