In personnel hoisting, what weight must the platform be loaded with for a proof test?

For a proof test in personnel hoisting, the platform must be loaded with 125 percent of its rated load. This is essential in ensuring the safety and reliability of the hoisting system. The primary purpose of the proof test is to confirm that the equipment can handle loads beyond its rated capacity without failure. By using 125 percent, it provides a necessary margin that accounts for variations in load distribution and potential dynamic forces that may arise during actual use.

This proof load helps to identify any weaknesses or defects in the platform or lifting mechanism before being used in real operational settings. It ensures that both the equipment and the safety systems are functioning correctly and can handle unexpected situations. Conducting the proof test at this percentage is a recognized industry standard aimed at promoting safety and preventing accidents during personnel hoisting operations.
