State of Loading and total duration of useing are the factors used to determine the hoist classification that should be used: M1, M2, M3, M4, M5, or M6. Cross referecing the two factors with one another will lead to a classification choice in the Chart

Examples:

1. A hoist that would be subjected frequently to the maximum load and, normally, to loads of heavy magnitude (a “heavy” state of loading), that requirement a lift span of 1600 hours should be in classification group M5.

2. A hoist that would be subjected very rarely to the maximum load and, normally, to light loads (a “light” state of loading), that requires a life span of 6300 hours should be in classification group M4.
