Mining Hoists
Mining hoists are elevators used in underground mines and mineshafts. They are used to move equipment, personnel, and ore to or from the surface or different depths within the mine. They are also known as lifts, elevators, shaft hoists, and whim. They are an indispensable tool in any mine.
Mining hoists are typically powered by electricity, using an underground power supply or stored power in battery packs. The attachment points and corresponding mechanisms on the hoist itself vary by model, but usually use either a hook and chain, ropes, cables, or a combination of all three, depending on the payload being lifted and the maximum capacity of the unit.
Hoists are designed for safe, reliable operation in highly hazardous working environments and need to be able to withstand a range of environmental factors including vibration, extreme temperatures, and explosions. The permanent hoists are typically custom made for specific mining operations, unless a mining company chooses to purchase a stock configuration from a manufacturer.
When selecting a mining hoist, it’s important to consider the size, the weight of the payload, ease of use, and overall costs. The hoist should be customized to fit the mine’s requirements, matches the current technology, and that the necessary certifications are met.
The speed of the hoist as well as the safety features are two of the most important considerations when selecting a mining hoist. Fast hoists are required for efficient operation of large mines and for supporting high-production operations. High levels of safety must be observed due to the hazardous environment and strict regulations governing the mining industry. Many hoists are equipped with anti-lock braking systems to ensure sudden stops are safely managed and new technologies such as dynamic frequency drives are also being incorporated into mining hoists to enhance their performance.
The cost of mining hoists depend on the type, size, and features, but overall they are a useful investment for any mining operations looking to improve safety and efficiency. They are available through a variety of manufacturers who specialize in mining equipment and are sure to be an asset to any mine.
