Second-hand single-girder gantry cranes refer to gantry cranes that have been used for a period of time and are usually sold due to factory relocation, equipment upgrades, or financial reasons of the original owner. Purchasing a used gantry crane is often more economical than purchasing a new overhead crane.
Single-beam gantry crane is a common lifting equipment, usually used in factories, warehouses, freight yards and other places for material handling, loading, unloading and transportation. Its structural feature is that it has a gantry structure with a beam between the two legs, like the shape of a “door”, hence the name “gantry crane”. Compared with double-girder gantry cranes, single-girder gantry cranes have a simpler structure and are suitable for light-load, medium- and small-span lifting operations.
