Mining systems heavily rely on hoists to transport equipment, personnel as well as mined ore to the surface. As such, the hoisting system is the core productive element in the mining industry. Due to this, it’s essential to investigate the mining hoist systems available to you, as they can solve core challenges faced by mining companies such as productivity rates, energy consumption rates and the overall safety of production.
Why Are Hoists Important in Mining Applications?
Mining refers to the extraction of valuable minerals or materials from the Earth. In the case of sub-surface (underground) mining, the mine hoist acts as a bottleneck between the mine and the surface. The correct selection of hoisting equipment, as well as consistent condition monitoring, is imperative to ensure both productive and safe mining operations. Due to the high hourly capacity of hoists, hoist downtime in mining applications can be extremely costly.
For example, in 2009 at BHP’s Olympic Dam mine in South Australia, a failure in a hoists braking system resulted in a production fall of 75%. This cost the company close to $200 million in idle capacity costs and forced the temporary closure of the mine.
Most Common Types of Mining Hoists
The two main types of mining hoist equipment used today are the drum hoist and the friction hoist. The drum hoist physically stores the chain or rope during its hoisting cycle whereas, the friction hoist or drum drive works as a lever to pass the chain or rope over the wheel. Both pieces of equipment have unique benefits for each individual application.

Importance of Constant Monitoring
All of these safety features are programmed to work collaboratively, reliably and efficiently. As such, it’s essential that all working parts are regularly tested to provide protection against serious incidents. Constant monitoring is essential to maintain these safety standards, and even if you believe your hoisting system is working correctly, there is potential for underlying issues to be present. When undergoing regulatory monitoring, closer inspection may be required if the hoist is displaying:
- Mechanical or tread wear compensation
- Drift in the duty cycle
- Abnormal noises
- Change in emergency deceleration rate during an emergency stop
- Changes in running temperatures, motor or bearings.
