MG (U-type) double girder gantry cranes enable efficient outdoor heavy material handling.

In outdoor operations at heavy manufacturing plants and large material yards, open-air hoisting has long faced challenges such as large spans, complex wind conditions, and continuous heavy-load operations. Traditional light-duty lifting equipment suffers from insufficient structural rigidity and weak wind resistance, making it difficult to meet the demands of routine heavy material handling. To address these pain points in outdoor heavy-load operations, the industry widely adopts MG (U-shaped) double-girder gantry cranes to construct standardized outdoor hoisting systems. Relying on mature structural design and reliable adaptability to various working conditions, these systems comprehensively improve the standardization and efficiency of outdoor hoisting operations.

This equipment employs a double-box main beam structure paired with U-shaped flexible legs, resulting in strong overall frame stability and excellent bending and torsional resistance. It effectively resists outdoor wind interference, maintaining stable operation without swaying under heavy loads, making it suitable for large-span, large-tonnage outdoor hoisting scenarios. The equipment does not rely on factory building structures, operating independently via ground tracks, making it highly adaptable to different sites. It can be widely used in steel structure stacking, large equipment assembly, building material storage, and dock material handling. Compared to ordinary gantry cranes, this model offers a wider working range and greater load redundancy, adaptable to high-frequency, uninterrupted continuous operation.

In practical applications, the equipment is equipped with a comprehensive safety protection system, integrating multiple protection functions such as limit protection, buffer collision avoidance, windproof anchoring, and emergency power failure, effectively mitigating operational risks posed by complex outdoor environments. It also supports multiple control modes and can be coupled with a variable frequency speed control system according to site requirements, achieving smooth start-stop and precise positioning for refined hoisting. Through standardized equipment deployment, the process standardization of outdoor heavy-duty operations is significantly improved, equipment maintenance frequency is reduced, and manpower input is greatly decreased, providing stable and reliable lifting support for outdoor heavy industrial production, material storage, and engineering construction, and contributing to the standardization upgrade of the factory's production and transfer system.
