Liebherr has modified its LR 1750 crawler crane with the upgraded 750-ton LR 1750/2 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%.
Boom
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 LR 1600/2, the strengthened boom systems on the LR 1750/2 together with the derrick system has been given the suffix ‘H’ (Heavy) which stands for powerful, heavy boom systems.
Ballast trailer and platforms improvements
The ballast trailer has also been modified as part of the modification to the Liebherr 750-ton 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.
Compatibility
During its modification of the LR 1750, 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.
