What is the required interval for non-destructive tests of elevator drive components after initial operation?

• A. Every 6 months
• B. Every 12 months
• C. Every 24 months
• D. Every 18 months

Answer: (B)

The requirement for performing non-destructive tests on elevator drive components after their initial operation is set at an interval of every 12 months. This annual testing is crucial for ensuring both the operational safety and reliability of the elevators, especially in a mining context where harsh conditions can significantly impact the integrity of equipment.

Regular non-destructive testing allows for early detection of potential defects or degradation in materials, which could lead to catastrophic failures if left unchecked. By adhering to this 12-month schedule, operators can maintain a high standard of safety and performance for their elevator systems, ensuring compliance with safety regulations and minimizing downtime due to unexpected maintenance issues.
