Application Scenarios
| New construction and deepening projects of mine shafts: used for lifting blasted rock debris. |
| Vertical shaft excavation projects such as large bridge pile foundations and ventilation shafts in hydropower projects. |
| Lowering of underground materials and equipment: empty buckets or buckets loaded with support materials (such as cement, anchor rods) can also be safely lowered. |
Comparison with other types of bailers
| Type | Unloading method | Safety | Efficiency | Main uses |
| Hook bucket | Automatic, flipping via seat hook and curved rail | Very high | Very high | Shaft sinking |
| Tilting bucket | Manual or mechanical pushing of the flipping frame | Relatively low, requires operation at the shaft mouth | Relatively low | Small-scale mines or auxiliary operations |
| Bottom-discharge bucket | Opening the bucket bottom gate | High | High, but with requirements for the material | Concrete pouring, granular material transportation |
| Ordinary muck bucket | Manual direct dumping | Very low, hazardous | Low | Largely phased out |
