Cheaper and More Efficient Ship Loading Equipment
Commodity cargo that is transported on ships can be either packaged or unpackaged. Unpackaged cargo in large quantity is also referred to as bulk cargo, which has granular, particulate or liquid form. Coal, grain, gravel, and crude oil are common bulk cargo that can be transported on ships and railroad wagons. To transport the cargo, it needs to be poured into a bulk carrier on the ship or wagon. A specific machine is used to pour the cargo to the bulk carrier. Usually, a hopper crane is used to load the cargo. However, a more efficient machine called shiploader is now being used to pour the cargo on ships docked on the river or sea harbor.
Compared to hopper crane, ship loading machine is considered more advantageous. There are at least two reasons why this machine is more preferable than hopper crane. First, having simpler construction with fewer metal components, ship loading equipment is much cheaper to buy than hopper crane. Second, instead of using cyclical conveyor feed, this loading machine uses continuous one. As a result, loading time can be reduced significantly. By using hopper crane, only 500 to 1200 tons of cargo can be loaded in one hour. By using the loading machine, that number can be multiplied almost three times. 2000 to 3000 tons of load can be loaded in one hour using a loading machine.
