Both 4-rope grab cranes for heavy-duty bulk handling have 63-tonne grab curves and maximum radii of 50 m. They can be used alongside ships up to Capesize at handling rates up to 1,800 tph. To be manufactured in Düsseldorf, Germany the cranes are expected to start operations at the end of 2010 and they are expected to handle about 15m tonnes/year.
The two cranes use proven mobile harbour crane technology from the slew ring upwards and the portals are designed with a track gauge of 13 m and a clear height of 6 m adapted to the individual conditions in the port. The electrically driven cranes obtain their energy from the shore supply.
Gottwald first used its mobile harbour crane technology on a portal built together with a US operator in 1998 and with the two latest cranes for India, has increased the total number of this type of crane to 37.
