The announcement came during the Shipbuilding, Machinery and Marine Technology International (SMM) exhibition in Hamburg, Germany. The manufacturer currently offers models from 120 to 450 tonnes capacity. “The heavy lift crane series will be gradually adapted over the coming years and it is planned to extend the product range by one type per year,” said a company spokesman.
Liebherr-Werk Nenzing, in Austria, already produces models up to 2,000 tonnes for the offshore crane sector. In addition, a new kind of subsea crane, the RL-K 7500, has recently been developed for subsea operations. It has a knuckle boom for underwater work as well as an active heave compensation (AHC) system and can lift up to 270 tonnes above the water surface and lower loads down to a depth of 3,000 metres.
During AHC operation 40% of the required power is provided by active power from primary energy and 60% is obtained from passive power through the Liebherr Pactronic system.
Liebherr-MCCtec Rostock, in Germany, is considered to offer particular opportunity for maritime expansion, said the manufacturer. The site produces mobile harbour cranes, ship cranes, floating cranes, offshore cranes and reachstackers and is well placed for large international equipment sales, said the manufacturer.
Details about the product launches will be announced after the SMM 2012 trade fair.
