The QD hook bridge crane, a widely used lifting machine, primarily consists of a bridge structure, crane travel mechanism, trolley, and electrical systems. Its key feature is the hook as the load-handling device. The standard configuration is a double-girder design comprising a welded box-section main girder, end carriages, a hoist trolley with lifting and traversing mechanisms, and a complete electrical control system.

Rails are laid on the main girders for the trolley to traverse. The main girders are welded to box-shaped end carriages, which feature bolted joints at their midpoints to facilitate segmented transportation. A platform is installed for mounting electrical equipment and provides maintenance access. A full-view cabin is suspended beneath the main girder, housing a combined or separate control desk. Access is provided via a side ladder connecting the cabin to the platform.

Operation & Control:
Three operation modes are available: pendant control, wireless remote control, and cabin control. Cabins come in open or enclosed types, equipped with an adjustable seat, insulated floor mat, toughened glass windows, and essential safety items like a fire extinguisher. Optional accessories include an air conditioner, audible alarm, and intercom.
