Typical Applications for Grab-Type Double-Girder Overhead Cranes?

The grab-type double-girder overhead crane is primarily designed for handling bulk materials; it features automated loading and unloading capabilities and eliminates the need for manual hooking. Its application scenarios are highly focused, centering mainly on the handling of loose bulk materials, loading and unloading operations in stockyards, and internal material transfer within workshops and warehouses.

Typical Application Scenarios for Grab-Type Double-Girder Overhead Cranes
Loading and Unloading in Bulk Material Warehouses and Stockyards
Coal, coke, ores, sand and gravel, limestone, gypsum, clay, etc.
Feeding, transferring, and stockpiling operations within cement plants, stone quarries, coking plants, and coal yards.
Grain and Agricultural Product Processing
Handling operations in grain silos, feed mills, and flour mills: bulk grains such as corn, wheat, soybeans, paddy rice, etc.
The grab mechanism can be designed to be fully enclosed, preventing material spillage and minimizing dust generation.
Waste Treatment and Solid Waste Disposal
Municipal waste incinerators, waste transfer stations, and solid waste treatment centers.
Grabbing and handling municipal waste, sludge, excavated soil, and construction debris.
Material Feeding in Metallurgical and Mining Workshops
In steelworks, smelters, and sintering workshops: grabbing ore fines, sintered materials, and slag.
Facilitating continuous material feeding and transfer in coordination with production lines.
Bulk Cargo Transfer at Ports, Docks, and Freight Yards
At inland river docks and freight stations: grabbing bulk cargo from trucks or ship holds for storage.
Suitable for use in enclosed indoor silos and semi-enclosed material sheds.
Raw Material Workshops in Chemical and Building Material Industries
Handling chemical powders, granular raw materials, cement clinker, slag, etc.
Meeting the demand for continuous, high-efficiency, and contact-free material handling.
Applicable Working Condition Characteristics
Materials: Loose, granular, powdery, or lumpy; not suitable for unitized (packaged) cargo.
Environment: Indoor or semi-indoor settings featuring fixed hoppers, silos, or storage pits.
Requirements: Frequent grabbing operations, automated unloading, high efficiency, and elimination of manual hooking.
Comparison: Better suited for handling bulk materials than standard hook-type overhead cranes; better suited for indoor factory environments than gantry cranes.
