FEM 9.825 - Series Lifting Equipment: Power driven series hoist mechanisms - Standardised test procedure for verification of the classification

FEM 9.852-EN

This Rule applies to power driven series hoist mechanisms in the scope of application of FEM 9.511. This Rule does not deal with the load bearing means employed (ropes, chains, belts).

The calculated classification of series hoist mechanisms is effected according to FEM 9.511 "Rules for the design of series lifting equipment - Classification of mechanisms". The theoretical duration of service table 1 in FEM 9.755 "Series lifting equipment - Measures for achieving safe working periods for power driven series hoist mechanisms (S.W.P.)" is also based on FEM 9.511. The verification of the dimensioning and classification of series hoist mechanisms according to the specified rules is effected by the manufacturers using mathematical methods and tests.
