رافعات جسرية
The U-type double-girder outdoor gantry crane features a unique "U" shaped frame design. Compared to A-type gantry cranes, it eliminates the need for supporting saddles, providing a wide leg span of nearly 7 meters, facilitating the loading and unloading of large goods such as containers. The crane has a low overall height, strong stability, and can operate along ground rails, offering a wide working range. The main beam can be equipped with cantilevers, supporting operations beyond the span.
It is suitable for ports, railway freight yards, open-air storage yards, and other locations for efficient heavy-duty handling. With a maximum lifting capacity of up to 50 tons, it is a robust, durable, and highly adaptable heavy-duty lifting equipment.

Outdoor gantry crane typically consists of the following main components:
Railway Freight Yards: Used for loading and unloading goods from railway open wagons and covered wagons, accelerating railway logistics turnover.
Open Storage Yards and Warehousing: Used for lifting, stacking, and warehousing management of heavy goods such as steel, timber, and large equipment.
Heavy Industry and Manufacturing: Used for lifting steel billets and profiles in steel mills; handling large components in heavy machinery manufacturing workshops; and material transfer and equipment installation on production lines in various factories.
Large-Scale Engineering Construction: Used on construction sites for subways, bridges, and high-rise buildings to lift prefabricated components, reinforcing bars, pipe segments, and other large building materials.
Production Line Transportation: Used for material transportation on production lines and lifting operations during processing.

Outdoor gantry cranes are the ideal lifting solution for open spaces and are widely used in material handling operations at construction sites, logistics stations, and manufacturing areas. They are specifically designed to withstand harsh weather conditions and heavy-duty operations, offering flexible configurations to suit a variety of application requirements. Depending on your operational needs and working environment, there are several outdoor gantry cranes to choose from, including:
Features a single main beam structure with an electric hoist operating beneath the main beam, typically in a simply supported configuration.
التطبيقات: Suitable for outdoor material handling of medium to small tonnage, such as warehousing areas, equipment loading/unloading zones, construction sites, etc.
المزايا: Lightweight structure, low cost, easy installation, particularly suitable for limited space or temporary operational requirements.
Features a double main beam design, with an electric hoist or trolley operating between the two main beam tracks, offering strong overall load-bearing capacity.
التطبيقات: Widely used in heavy-duty equipment handling, container yards, steel markets, and other high-intensity operation areas.
Key Advantages: High lifting capacity, wide span, and smooth operation, suitable for high-frequency, high-load professional operation requirements.
Trackless design with rubber tires for mobility, powered by diesel engines, electric motors, or hybrid drive systems.
التطبيقات: Commonly used in container yards, shipyards, and precast component handling areas, capable of flexible movement to different work sites.
المزايا: High mobility, no need for fixed tracks, and flexible steering, suitable for large-area operations and frequent site transfers.
One side operates on ground tracks, while the other is supported by elevated structures (such as factory building or wall tracks).
التطبيقات: Commonly used for handling or loading/unloading operations in special layouts such as along factory building exteriors, workshop corridors, or assembly lines.
المزايا: Space-saving structure, suitable for asymmetric work areas, facilitates integration with factory building structures, and reduces civil engineering costs.
