Engineered for demanding outdoor applications, our Double Girder Grab Bucket Gantry Crane delivers robust performance in open-air storage yards and alongside railway tracks. Its operation is highly flexible, supporting control from a secure driver's cab or via convenient ground-based systems. The crane's distinctive "A"-frame structural design ensures superior stability and load-bearing capacity. With a typical span range of 18 to 35 meters, this mobile rail crane is perfectly suited for material handling tasks in the outdoor yards and workshops of metallurgical, cement, and chemical processing plants. It efficiently transports a wide array of bulk materials, including ore, limestone, coal, sand, and other granular substances, across fixed indoor or outdoor spans.
The integrated grab bucket mechanism is specifically designed for handling loosely piled, non-compacted bulk solids. For specialized operations involving underwater materials or other unique substances, please provide detailed specifications at the time of ordering. Furthermore, we offer comprehensive waterproofing kits to ensure reliable, all-weather operation when the crane is deployed in exposed outdoor environments.
A Double Girder Grab Bucket Gantry Crane is a robust and versatile overhead lifting solution engineered for the high-efficiency handling of bulk materials. Unlike standard cranes, it is equipped with a specialized grab bucket that acts as an integrated loading and unloading tool, eliminating the need for manual labor and significantly accelerating operations. This crane is an essential asset for industries requiring rapid movement of loose materials such as coal, ore, sand, grain, scrap, and timber.
Our models are available in 5-ton and 10-ton capacities, built on a reliable double-girder design for superior strength, stability, and lifting performance over long spans.
Key Features & Benefits
High Productivity: The motorized grab bucket opens and closes seamlessly, allowing a single operator (via cabin or remote control) to grab, lift, transport, and dump materials in one continuous cycle. This automation drastically reduces cycle times and labor costs.
Durability & Stability: The double girder construction provides exceptional structural integrity, capable of supporting heavy loads and the dynamic forces of the grab operation across spans up to 35 meters. This ensures long-term reliability even in demanding, 24/7 environments.
Precision & Control: Equipped with powerful and responsive hoisting and travel motors (YZR series), the crane offers smooth acceleration and precise load positioning. Dual-speed options on long travel allow for careful maneuvering when needed.
Operational Flexibility: Designed for both indoor and outdoor applications, it is ideal for fixed material yards, storage areas, ports, and logistics hubs. The ±10 meter lifting height provides ample clearance for loading/unloading from trucks, railcars, or stockpiles.
Safety & Reliability: Built with industrial-grade components and fail-safe braking systems. The clear separation of the operator from the load area enhances job site safety.
