A container gantry crane is the biggest crane which is used in the operation sector of the shipping industry. It is designed for loading and unloading the container cargo from a container vessel.
The shipping container gantry crane is operated by a specially trained crane operator from within the cabin located on the top end of the crane and suspended from the trolley. It is the operator who lifts the container from the ship or dock for unloading or loading of cargo. It is very important for both the ship and the shore staff (gantry operator, stevedores and foremen) to be alert and to maintain proper communication between them to avoid any accidents.
Supporting Frame: The supporting frame is the giant structure of the rmg container crane which holds the boom and the spreader. For transverse movement of the crane in the jetty, frames can be rail mounted or moved by rubber tyres only.
Transverse operator cabin: It is incorporated in the bottom of the support frame, in which, a crane operator, for transverse movement of the crane in the yard, will sit and operate.
Boom: The boom of the container gantry crane is hinged at the water side, so that it can be moved up and down as per the requirement of the cargo operation or navigation. For smaller gantry, where there is a fly zone located near the port, low profile booms are used which are pulled towards the gantry when off operation.
Spreader: Spreader is attached with the operator’s cabin on the rail structure and in the boom so that it can also move transversely on the boom for lifting cargo. The spreader itself can open and close depending upon the size and the number of containers to be lifted. The modern built spreader can lift up to 4 containers together.
Gantry operator cabin: Located at the top of the supporting frame, the cabin is 80 % transparent so that the operator can get a clear view of the loading and unloading operation.
