What should automatic hoists be equipped with to ensure safety during power failures?

Automatic hoists should be equipped with devices that automatically apply the brakes to ensure safety during power failures. This feature is crucial because, in the event of a power loss, the hoist can descend uncontrollably, posing a significant risk to personnel and equipment. The automatic brakes engage to securely hold the load in place, preventing accidents and injuries.

Ensuring the stability of the load during unexpected disruptions is a fundamental safety principle in mining operations. While other options like emergency lights or manual control overrides can enhance safety, they do not specifically address the immediate risk associated with a power failure as effectively as an automatic braking system does. The application of brakes is a direct response to maintain control over the hoist and its load, making it a standardized safety requirement in the industry.
