A single girder gantry crane is a general-purpose lifting device with a simple structure, widely used in various job sites. It is commonly employed in workshops, warehouses, and construction sites for material handling tasks. The single girder gantry crane uses an electric hoist as its lifting mechanism, allowing for efficient and stable operation.
The main beam, located at the top of the crane, is a horizontal component and serves as the core load-bearing part of the gantry crane. Its primary function is to support the electric hoist and bear the weight of the lifted materials. Two support legs, attached vertically to both ends of the main beam, form the "gantry" frame. These legs provide stable support, enabling the gantry crane to move on the ground or along a track.
The traveling mechanism, located at the bottom of the support legs, consists of wheels or a drive system. It allows the gantry crane to move horizontally on the ground or on dedicated tracks, expanding the working area. Safety features include components such as limit switches, emergency stop buttons, and overload protectors.
Used for material handling, equipment installation, and maintenance on production lines.
Mainly for loading, unloading, stacking, and transferring goods in warehouses.
Lifting and moving light construction materials and equipment to improve work efficiency.
Suitable for loading, unloading, and short-distance transportation of small goods.
Used for equipment maintenance, parts replacement, and other related tasks.
