A hoist is a compact lifting device designed for short-distance operations, suitable for diverse environments. Today, we’ll discuss the crucial considerations for safely using a hoist in a mine.
A hoist in a mine offers convenience in transporting materials from the shaft to the surface, saving both time and effort. However, its underground application differs significantly from its surface use. The confined space and numerous unpredictable factors underground require utmost caution. Mishandling can lead to accidents at any moment.
To ensure safe underground usage, it’s crucial to adhere to strict operating procedures and safety guidelines. Regular maintenance and inspections are also necessary to ensure the hoist’s reliability and performance. With proper care and attention, a hoist can be a valuable asset in any mining operation.
So how can the hoist be used underground?
Underground Hoist Operation
Pre-Operational Inspection:
- Thoroughly inspect the hoist handle and its components. Ensure all parts are in optimal condition before use. Any deformities in the shell, abnormal sounds, loose parts, or cracks in the chain hook render the hoist unfit for use.
- Verify the reliability of the hoist‘s fixation point. Effective fixation is crucial before using the hoist. A falling hoist in the lifting process could lead to a severe accident.
- Post-fixation, double-check the hoist‘s condition to prevent accidental damage due to collisions or improper handling.
- Assess the underground environment. With limited space and poor lighting, ensure the hoist’s workspace is adequate. Keep the area as clean as possible, avoiding debris accumulation.
Operational Considerations:
- Test the hoist on the ground before underground use. Ensure its functionality and reliability before deploying underground.
- Clearly identify the hoist‘s load capacity and avoid overloading.
- When lifting underground, maintain a safe distance from the hoisted weight to prevent any accidents.
- Strictly adhere to using one hoist for lifting one item. Concurrent usage of multiple hoists is prohibited.
- Avoid leaving heavy objects suspended in the air for prolonged periods while lifting manually.
- Promptly clean the hoist after use. The underground’s damp environment can cause rust, so remove any lingering water vapor to preserve the hoist’s integrity.
