First job for a unique 750 ton mobile crane
The world's heaviest mobile crane performed its first commercial on 22 February 2013, for Mammoet. The company deployed its brand new Liebherr LTM 1750-9.1 to lift a 340 ton temporary support leg for an offshore drilling rig. Another first was that this was the first time a load this heavy was lifted by mobile cranes only. The new 750 ton crane undertook the job together with two 700 ton mobile cranes. The three cranes needed two hours to lift the leg from the water onto an offshore supply ship. The support was used for the repair of the GPS Saturn drilling rig moored in IJmondhaven. It was temporarily placed under the rig so that one of its 120 meter high legs could be repaired.
The Liebherr LTM 1750 9.1, with a capacity of 750 tons, is the world's largest self-assembling mobile crane. It does not need a second crane to install the boom and other basic components. This means the crane, with a weight of 108 tons and fitted with nine axles, can be mobilized and demobilized quickly and it offers great operational flexibility. The standard boom extends to 52 meters and can be used in other configurations for a greater height or radius. The maximum lifting height is 154 meters and the maximum radius is 112 meters. Mammoet has ordered six of these 750 ton cranes. Its unique capacity makes this behemoth perfect for applications in civil engineering, petrochemicals, wind turbines and offshore structures - all sectors where there is a growing demand for cranes which can lift ever heavier loads further and higher.
