Product Description

Product Description

A bridge crane is a lifting device that is horizontally mounted above a workshop, warehouse, or material yard to lift materials. Because its two ends are located on tall concrete columns or metal brackets, it looks like a bridge. The bridge of a bridge crane runs longitudinally along the tracks laid on the elevated platforms on both sides, making full use of the space under the bridge to lift materials without being hindered by ground equipment. It is the most widely used and most numerous type of lifting machinery.
A double box girder gantry crane is an overhead crane built on top of a structure that is supported by freestanding legs, eliminating the need for an overhead runway system. Gantry cranes are built on movable frameworks with wheels that enable the structure to be moved along a track or rail system.
Double Box Girder gantry crane are designed with two girders configuration, providing various load capacities. Double box girder gantry crane are used to lift extremely heavy loads.
Double Box Girder gantry crane are designed with the highest engineering standards for safety and high performance by advanced technology. Manufactures and supplies custom double girder gantry crane with the capacity up to 300 tons and span up to 50 meters for your demands.
