Which two devices must be fitted for high-speed hoisting operations?

Explanation:
The main idea is to ensure both immediate control and a verifiable record of hoist speed during high-speed operations. A tachograph provides a time-stamped record of the hoist’s speed over time, giving you a traceable history for safety audits or incident investigations. A speed indicator, on the other hand, shows the current rope speed to the operator in real time, allowing immediate actions to keep the operation within safe limits. Together, they ensure you can monitor speed live and have a documented history of how fast the hoist moved, which is essential for safety and accountability. The other options either miss the live speed display or lack a proper recorded log, so they don’t meet the dual need of real-time visibility plus documented history.
