Which is better—bridge cranes or gantry cranes, and how should you choose?
Bridge cranes and gantry cranes are currently the two most widely used types of lifting equipment, with bridge cranes being the dominant one. A bridge crane consists of a trolley that travels along fixed support pillars spanning between building structures, and it can be categorized into several types: general-purpose bridge cranes, power plant bridge cranes, explosion-proof bridge cranes, electric single-beam bridge cranes, electric single-beam suspended bridge cranes, electric hoist bridge cranes, metallurgical bridge cranes, and insulated bridge cranes. These cranes are primarily used for loading, unloading, and lifting heavy materials—either indoors or outdoors, though indoor applications are more common. One of their key advantages is that they don’t occupy valuable floor space, making them highly efficient in terms of area utilization. Additionally, among all crane types, bridge cranes are not only the most affordable but also offer exceptional cost-effectiveness, making them an ideal choice for many industrial and logistics operations.
A gantry crane is also a lifting device used for moving and loading/unloading materials within a fixed span. The key difference between it and an overhead bridge crane lies in the structure of the bridge girder: while the bridge crane features a single continuous beam, the gantry crane has two tall supporting legs at each end of its main beam. The large trolley’s wheels are mounted directly onto the bottom beams of these supporting legs, allowing the crane to move longitudinally along tracks laid out on the ground. Gantry cranes can be categorized into several types, including general-purpose gantry cranes, power plant gantry cranes, shipbuilding gantry cranes, quay container handling bridges, and truss-type cargo-handling bridges. These cranes are widely employed in workshops, warehouses, or open-air storage areas—though their primary application is typically in outdoor settings.
Both bridge and gantry cranes can be used in both indoor and outdoor settings, with lifting capacities and spans ranging from small to large. The key difference lies in whether the site meets the requirements for installing a bridge crane: if the site already has supporting pillars, a bridge crane is the ideal choice, as it’s not only the most cost-effective but also the most stable option among the two types of cranes.
