Explosion-Proof Brakes for the Mining Industry 

Use Cases for Mining Equipment Brakes

Stearns is the only industrial brakes supplier that offers a line of Mine Safety and Health Administration (MSHA)-Certified motor brakes. All industrial brakes for mining applications are manufactured with a cast iron enclosure to eliminate the risk of fire or explosion caused by motors and other mining machinery in underground mines with elevated levels of toxic dust and gases.

What are the benefits of MSHA-Certified mining equipment brakes? 

The MSHA is responsible for evaluating and approving the safety, security, and reliability of underground, electric mining vehicles used to search for, extract and process natural occurring minerals within the earth such as coal, gold, platinum, tin, gravel, clay, salt, and more. MSHA-certified brake enclosures manufactured by Stearns enhance the safety and performance of semi-stationary mining equipment that depends on a motor, making them ideal for all mining methods including: room and pillar mining, retreat mining, and blast mining.

Stearns’ spring-set, electrically-released mining brakes supercharge uptime, advance system reliability, and automate processes with zero-emission motors to promote miner safety and well-being.
