The brake of a non-positively driven material hoist must be capable of holding 150% of the rated load. This requirement is in place to ensure safety and reliability when lifting heavy materials. The rationale behind this standard is to account for dynamic forces that may occur during operation, such as sudden starts and stops, or potential overload situations. By requiring the brake to hold 150% of the rated load, it provides an additional safety margin to help prevent accidents, ensuring that even under unexpected conditions, the equipment remains secure and operational.

In the context of material hoists, which often deal with varying loads and potential external factors, maintaining this higher safety factor for braking capacity is essential. While other options represent percentages that are lower than the standard specification, they do not provide the adequate level of safety necessary for the equipment to function effectively in a range of operational scenarios.
