A SHIP UNLOADER OFTEN TAKES THE FORM OF A CRANE
A ship unloader/loader arm (also referred to as a manipulator) looks like a crane. As the name suggests, it is used to offload cargo. Each model is designed to handle a particular type of cargo including containers, grain, liquids or bundles.
Unloader manipulators are used in commercial ports. There are versions available for practically every type of merchandise.
Most unloaders are articulated cranes, either stationary or riding on wheels, rails or caterpillar tracks. Offloading capacity is measured in tonnes per hour. Some manipulators are equipped with vacuum or other tank-cleaning systems, which are used at the end of the unloading process.
Continuous operation versions unload suitable merchandise (e.g., cereals) in an uninterrupted flow via augur, bucket elevator or wheel.
