This gantry crane is working by traveling rails on the ground, mainly used in open-air storage yard, docks, power plants, ports and railway stations and other places for cargo handling and installation operations. Gantry crane hoisting mechanism, trolley traveling mechanism and bridge construction, are basically same with bridge crane. Because of long span, gantry crane are usually used by respective driven way to prevent the crane producing skewed running and increasing the resistance, and even accidents.
It is mainly used for the loading and unloading operations of freight yards, yard goods, and bulk cargoes. Its metal structure is like a gantry frame, bearing two feet under the main beam, and can directly walk on the track of the ground. Both ends of the main beam can have an outrigger cantilever beam. The gantry crane has the characteristics of high site utilization rate, large operating range, wide adaptability and strong versatility and is widely used in the port cargo yard.
Advantages of gantry cranes
Gantry cranes with the runway located on the floor can be used where the overhead crane or bridge is not practical.
Gantry cranes are more cost-effective comparing with the overhead crane system.
Types of gantry cranes have a wide application. Gantry can be used indoors and outdoors. Gantry cranes can be used when the existing factory structure which cannot bear the wheel loads of the overhead crane; or loads needs to be handled outside the crane span and when the relocation of the crane is required after the work at a certain site is completed.
