Korean customer places an order for two large Liebherr cranes with 3,150 mt and 4,000 mt load moment
Liebherr-Werk Biberach GmbH has been awarded an order to supply two large cranes by Daewoo-Shipbuilding & Marine Engineering Co., Ltd. (South Korea).
Daewoo-Shipbuilding & Marine Engineering Co., Ltd. (South Korea) placed an order with Liebherr-Werk Biberach GmbH for the supply of a large 3150 HC 70 crane for stationary application at a Korean shipyard. In order to handle large prefabricated ship components, this crane will have a load moment of 3,150 mt.
The complete crane which will be permanently installed on a gantry weighs 570 tonnes. It has a hook height of 45 m and a maximum working radius of 60 m. The maximum load capacity at a working radius of 60 metres is 55 metric tons in 4-reeved hook operation, which corresponds to a weight of around 43 VW Golf cars. To suit local conditions, on the one hand, the crane has to run on rails and, on the other, allow large HGVs to pass through as part of a cross-traffic flow. This calls for a gantry with 12 x 12 m supports and a headroom of 9 m.
The drive and control equipment, which has been developed by Liebherr-Werk Biberach GmbH itself, enables the drives to be optimally matched to the particular application. All drivelines are continuously variable in speed.
The first 3150 HC 70 crane was delivered in March 2005.
An additional contract to build an even bigger crane has recently been awarded. This crane, the 4000 HC 70, will be a giant, with a load moment of 4,000 metric tons. It will be used in the same dockyard as the 3150 HC 70, and will be supplied to the customer at the end of 2005.
