Load and Unload Double Beam Gantry Crane
overview
The terms gantry crane and overhead crane (or bridge crane) are often used interchangeably, as both types of crane straddle their workload. The distinction most often drawn between the two is that with gantry cranes, the entire structure (including gantry) is usually wheeled (often on rails). By contrast, the supporting structure of an overhead crane is fixed in location, often in the form of the walls or ceiling of a building, to which is attached a movable hoist running overhead along a rail or beam (which may itself move). Further confusing the issue is that gantry cranes may also incorporate a movable beam-mounted hoist in addition to the entire structure being wheeled, and some overhead cranes are suspended from a freestanding gantry.
The quayside container crane is a container handling crane installed at large dockside for loading and unloading ship-borne containers to the container trucks. The dockside container crane is composed of a supporting frame that can travel on a rail track. Instead of a hook, the cranes are equipped with a specialized spreader which can be locked on the container.

features
The gantry of the double girder gantry crane mainly adopts a box-type double girder welded structure, which increases the working space and facilitates transportation, assembly and disassembly, and later maintenance. Double-girder gantry cranes are mainly suitable for open-air operations. According to different pick-up devices, they can usually be divided into hooks, grabs, and electromagnetic suckers (lifting electromagnets) or two or more grabbing devices at the same time. It is very common in factories, power stations, warehouses, stockyards and other places. The double-girder gantry crane consists of a main girder and outriggers, which are the main load-bearing parts of the crane. The lifting of the heavy object is realized by the lifting device installed on the trolley (or electric hoist); and the lateral displacement of the heavy object is completed by the running device of the trolley (or electric hoist).
