Today’s high-efficiency mines rely on effective hoisting and transportation systems to move people, goods, and equipment. Having the right hoists and safety equipment is essential for growing your operation while protecting your employees. Learn more about mining hoists, our upgrade and repair services, and Canadian regulations for surface hoist operations.
Mining Hoists Explained
Electric hoists raise and lower the conveyances in underground mines. Miners rely on them for daily operations: moving equipment, crushed ore, and people between the surface and the mining zone thousands of feet underground. In fact, mine hoists are often the only way to transport mining equipment and personnel to and from mining sites. Because human life depends on these systems, they need to provide consistent reliability with no risk of failure or miscalibration.
The electric components that control these hoists need to have the right power levels for these heavy loads and the right protections to ensure safe, reliable operation. Mining hoists commonly use electric motors powered by either AC motors with variable frequency drives or DC motors with solid-state converters. Drum hoists feature a sheave and headframe assembly, which are vital to the safe operation of underground mines.
At Renown Electric, we provide repair and troubleshooting services for AC and DC mining hoist motors and controls. Not only are our drive repairs tested for complete reliability, but we also offer controller trending and PMs to increase mine production and optimize cycle times.
Types of Electric Mine Hoists
There are many different types of mine hoists available for mining companies to select from, including:
- Blair hoists
- Escape hoists
- Friction hoists (Koepe hoists)
- Single drum hoists
- Double drum hoists
Each system includes digital controls, full automation, hydraulic brakes, motors, and drives. Powered with an electric or hydraulic drive, our team will work with your preferred partners to assist with assembly, factory or field testing, and commissioning.

Mining Hoist Regulations in Canada
Mining environments can be extremely hazardous, so equipment needs to meet strict standards to ensure the safety of workers and the efficacy of the worksite. The Coal Mining Occupational Health and Safety Regulations establish these standards in Canada, dictating the minimum requirements for surface hoist systems, from the framing and installation requirements of the system to the safety and emergency systems that must accompany each unit. The full list of regulations can be found here.
At Renown Electric, we take care to ensure all of our products and services meet or exceed these safety and performance requirements so you can operate your site with peace of mind.
