Both four-rope-grab cranes for raw bulk handling have 63-tonne grab curves and can be used up to Capesize class. From the slewing ring upwards, the cranes have mobile harbour crane technology and they have been adapted to the individual conditions in the port with a view to rail loading capacities, clearance and rail width.
According to the company, an important factor for many terminal operators is the electrical drive concept that enables the crane to be operated from external sources which not only makes operation cheaper, but also more environmentally friendly. Today, every second Gottwald crane operating in Turkey is powered by electricity from terminal mains.
All Gottwald harbour cranes can be equipped for operation by external power sources – either direct at the factory or by a subsequent upgrade. When power from the port mains supply is used, the on-board diesel generator is bypassed and the effectiveness of the drive train increased. This reduces the operating and maintenance costs and prevents exhaust fumes in the terminal. For new orders, Turkish customers insist on the use of external power sources while customers with cranes previously with operated diesel generators have been converting to using power from the port mains supply.
Last year Gottwald sold nine mobile harbour cranes to Turkey of which six were the model 7 of Generation 5 which, say Gottwald, with lifting capacities of up to 150 tonnes, are ideally suited for intensive, fast container handling on vessels up to post-Panamax class and for handling heavy and project loads
Three model 6 cranes were also sold and depending on the variant, have loading capacities of up to 125 tonnes and are also optimally suited to intensive container handling.
