March 4 - Liebherr had modified its LR 1750 crawler crane by strengthening the main boom and adjusting the derrick system, so that an upgraded 750-tonne capacity LR 1750/2 model is now available.

The adjustment of the derrick system included an extension of the derrick boom by 7 m to 38.5 m. The strengthened boom systems on the LR 1750/2 together with the derrick system have been given the suffix 'H', which represents 'heavy' boom systems, said Liebherr.

The ballast trailer has also been modified as part of the modification to the Liebherr 750-tonne crawler crane. The trailer now has a hydraulic drive unit, which the crane manufacturer says improves handling.

The upgraded crane also provides enhanced safety for operating personnel, said Liebherr, with additional platforms and access points, as well as extended and improved railings.

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