The gantry double-girder crane is a kind of lifting equipment with a stable structure and large lifting capacity, mainly used for material handling outdoors or in large production workshops. Its design inspiration comes from the "door" shaped structure, and thus it is called a "gantry" crane. Unlike bridge cranes, gantry double-girder cranes do not rely on the upper structure of the factory building. Instead, they support the crane frame with their own outriggers, enabling them to operate in open Spaces.
Main components
Double-girder structure: The gantry double-girder crane usually adopts two main girders set side by side to form a solid frame. This design enhances the crane's load-bearing capacity and is suitable for handling heavier objects of larger tonnage.
Outriggers: Outriggers are responsible for supporting the entire weight of the crane and ensuring stability. The design of the outriggers enables the equipment to adapt to different working environments, especially suitable for outdoor open Spaces.
Electric trolley or hoist: Installed on the main beam, it can move in the longitudinal direction, thereby enhancing the flexibility of operation.
Track system: The bottom of the crane is equipped with tracks, which support the entire gantry structure to move along the tracks and can cover a wide working area.
Main features
High load-bearing capacity: The double-beam structure enhances the stability of the equipment and is suitable for handling heavy objects such as large machinery and containers.
Strong adaptability: The gantry double-girder crane is not restricted by buildings and is suitable for use outdoors or in large factory areas, docks and other sites.
High flexibility: Materials can be transported horizontally and vertically through electric trolleys or electric hoists, ensuring high work efficiency.
Intelligent control: Modern gantry double-girder cranes are often equipped with intelligent control systems to enhance operational convenience and safety.
Application scenarios
Port: Used for the handling and loading/unloading of containers.
Shipyard: Used for the transportation and installation of heavy machinery and hulls.
Large manufacturing workshops: Widely used in heavy industries such as steel, metallurgy, and construction, they assist in the transportation of large components.
Overall, the gantry double-girder crane, with its outstanding load-bearing capacity, flexible operability and adaptability, has become an indispensable equipment in modern industrial handling.
