CG’s contribution to the modernization of Vladivostok’s sea fishing port

The Vladivostok Sea Fishing Port, Russia, is an international reloading port that besides fish products handling also carries out cargo operations of materials such as timber, metal, fertilizers, cellulose, combustive-lubricating materials, etc. The main area of the port consists of more than 323,700 m², and the capacity of the port is more than 5 million tons of cargo and 200,000 containers per year. The port has 41 bridge/gantry cranes, two of which are of the type “Kondor”.

Need for modernization

In 2013 it was decided to modernize the so-called Kondor cranes.
These cranes are a type of twin-control luffing and slewing portal crane which is used for the unloading of ships in the container terminal. The hoist of the crane operates with spreader, grab, electromagnet or hook. The customer’s request was it to get the highest handling capacity plus spot-on operating precision.
