Load Rating of Overhead Davit and Hoist System
Load Rating of Overhead Davit and Hoist System
(OP)
We have a self-fabricated swinging davit with a small electric hoist attached to it to support loading hoses in a chemical transfer operation. Question came up regarding proper load rating. Engineering calculations have yielded differing answers. Is there an empirical way to determine safe working load? It was suggested to lift up increasing amounts of known weight until slight permanent deformation (permanent sag from horizontal) is noted, then reducing that weight by a safety factor. Would this work/is this a proper method, and if so, how does one choose a safety factor?

During analysis, one must use proper safety factors, and impact loading.

The method of applying loads and observing deflections appears to be a bit crude, in these times.
