As an important hub for international trade, ports undertake important tasks such as cargo transportation, loading and unloading, and warehousing. In port logistics, rail mounted gantry cranes play a vital role and become key equipment for improving port operation efficiency and reducing operating costs.

The gantry crane is a bridge-type crane in which the horizontal bridge is set on two legs to form a gantry shape. This kind of crane operates on above-ground rails and is mainly used for transportation and installation operations in open storage yards, shipyards, power stations, ports and railway cargo stations.
