A number of newly developed products in the heavy lift crane sector are being planned. In addition, the existing sales activities are being intensified, also in the form of new strategic cooperations with sales partners.
Extension of the existing series of Liebherr heavy lift cranes
In the heavy lift crane division further new developments are planned. The lifting capacities of the existing Liebherr portfolio range from 120 to 450 tonnes. 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. The new series will include cranes with lifting capacities up to 1000 tonnes.
Liebherr-Werk Nenzing GmbH has vast experience and expertise in the field of heavy lift crane applications. A series of heavy lift cranes with capacities between 300 and currently 2000 tonnes already exists in the offshore crane sector. A completely new kind of subsea crane, type RL-K 7500, has recently been developed for subsea operations. The crane has a knuckle boom for underwater work as well as an AHC system (Active Heave Compensation) and can lift up to 270 tonnes above the water surface and lower loads down to a depth of 3000 metres. During AHC operation 40% of the required power is provided by active power from primary energy and 60% is obtained from passive power – Pactronic®. Liebherr Pactronic® is an innovative drive system on a hybrid basis and was initially developed for mobile harbour cranes and specially adapted to the AHC system for subsea cranes. In the mobile harbour crane divison Liebherr offers the LHM 600, the largest heavy lift crane available on the market. It features lifting capacities of up to 208 tonnes and has already been applied for several complex tandem lifts.
The knowledge from all product divisions and applications are actively integrated in new developments in the ship crane segment.
Further details regarding single developments will be announced after the SMM 2012 trade fair.
