Application Scenarios by Material Type
1. Coal Loading and Unloading
Suitable for power plants, docks, coal yards, etc.
Recommended Model: SWL 15t~40t (single-rope clamshell grab bucket capacity 9~25m³), as the density of coal is approximately 0.85~1.0 t/m³, which is close to the density of 0.9 t/m³ in the table.
2. Grain and Cereals
Used in grain depots, ports, food processing plants, etc.
Recommended Model: SWL 7.5t~15t (single-rope clamshell grab bucket capacity 4.4~9m³), as grain has a lower density (0.6~0.8 t/m³), a larger bucket capacity model can be selected.
3. Fertilizer and Ore
Suitable for fertilizer plants, mines, and bulk cargo terminals.
Recommended Model: SWL 20t~40t (single-rope clamshell grab bucket capacity 12.5~25m³), as the material density is higher, a high-strength, large-tonnage grab bucket is required.
4. Powdered materials such as cement and fly ash: Dust prevention and sealing are crucial; some grab buckets can be equipped with dust covers.
Recommended models: SWL 10t~25t (single-rope clamshell grab bucket capacity 6.5~15m³).
Application Scenarios Based on Operating Location
1. Inland Waterways and Small Ports: Smaller operation scale, crane tonnage generally not exceeding 25t.
Recommended Model: SWL 7.5t~15t, compact structure, lightweight, and highly adaptable.
2. Large Seaports and Hub Terminals: High-intensity operations and high efficiency requirements.
Recommended Model: SWL 25t~40t, used in conjunction with large gantry cranes or quay cranes.
3. Power Plants and Steel Plants: Used for stockpiling and handling of raw materials such as coal and ore.
Recommended Model: SWL 20t~40t, requiring wear resistance and long service life.
