Customized Box Type Double Girder Gantry Crane

The Customized Box Type Double Girder Gantry Crane is a heavy-duty lifting solution engineered for demanding material handling applications in factories, warehouses, construction sites, steel plants, shipyards, ports, and outdoor storage yards. Its box-type double girder structure provides high strength, excellent rigidity, and stable performance when handling heavy and large loads.

The crane consists of two main box girders supported by sturdy legs, with an electric trolley or hoisting mechanism traveling along the bridge. Compared with lighter crane configurations, the double girder structure offers greater load-bearing capacity and improved stability, making it suitable for frequent lifting operations and challenging working conditions.

A major advantage of this crane is its customizable configuration. SEVENCRANE can design the crane according to the customer’s specific requirements, including lifting capacity, crane span, lifting height, traveling length, working class, power supply, control method, and operating environment. Different hoist and trolley configurations can also be selected to meet various lifting applications.

The box-type girder is manufactured using high-quality structural steel and precision fabrication processes to ensure dimensional accuracy and structural reliability. The crane can be equipped with variable-frequency drive systems for smooth starting, braking, and speed control, helping improve positioning accuracy and reduce load swing during operation. Safety devices such as overload protection, limit switches, emergency stop systems, and travel protection can further enhance operational safety.

For outdoor applications, the crane can be configured with protective coatings and weather-resistant electrical components to adapt to different environmental conditions. Its independent supporting structure also makes it an ideal choice where a conventional overhead crane runway is unavailable.

With professional engineering, manufacturing, testing, and customization capabilities, SEVENCRANE provides reliable box-type double girder gantry crane solutions for customers worldwide. From factory production and steel handling to construction and heavy equipment lifting, this crane combines high strength, flexibility, safety, and efficient operation to meet diverse industrial lifting requirements.
