A double-girder gantry crane is a type of gantry crane that has two main girders; it is also known as a double-girder gantry crane or double-girder bridge crane, among other names. A double-girder gantry crane is equipped with four legs under its main girder, allowing it to move directly along tracks on the ground; the ends of the main girder can feature extended cantilever beams. It can be designed in the form of a truss or a private booth according to the user’s requirements. Advantages of the double-girder gantry crane: 1. The gantry features a box-type double-girder welded structure, which increases the working space and facilitates transportation, installation, and maintenance ； 2. For the conductivity of the trolley, special-shaped rails and flexible cables are used ； 3. Standardization, serialization, and generalization of components ； 4. The power supply methods for gantry cranes include cable reel type and slip ring type, allowing users to make a choice ； 5. The control room offers a clear view, enabling flexible control and stable operation. Fans, air conditioners, intercoms, etc. can also be added as required ； Operating environment conditions for double-girder gantry cranes: The operating temperature range for electric double-girder gantry cranes is from -20°C to +40°C. The operation mode can be one of three types: manual control, remote control, or wireless remote control. Electric double-girder gantry cranes are widely used in factories, warehouses, and logistics facilities. It is prohibited from being used in operations with risks such as flammability, explosiveness, corrosion (acids, bases, zinc vapor), high-temperature solutions, overloading, and powders. For operations in special environments, please contact us to describe the situation so that we can develop a customized plan. Uses: The gate frame structure comes in box-type and truss types; the box-type version is easier to manufacture, while the truss type has a lower weight and greater wind resistance. The entire machine features a low weight, simple structure, and easy installation and maintenance. It is suitable for use in outdoor locations such as factories, warehouses, and freight yards with moderate lifting capacities, for general loading, unloading, and lifting tasks.
