A dock crane, also known as a quay crane, is a large lifting device used to load and unload cargo onto/from ships at docks. It is a key piece of equipment for cargo hoisting. Depending on different requirements, it can be fixed on the shore or equipped with a traveling mechanism to move flexibly within the dock.
Metal Structure： It includes the boom, tower body, and base. The working mechanisms consist of four parts: hoisting, luffing, slewing, and traveling.
Electrical System： It includes motors, controllers, power distribution cabinets, connecting wires, signal and lighting equipment, etc.
Dock cranes can be equipped with automatic container spreaders, hooks, or grabs for loading and unloading containers, general cargo, or bulk cargo.
