Any solid reference of typical load factors for mechanical equipment?

[Dvhez]

I work in the mining industry and we use a table that has load, operating and demand factors for every type of load (conveyors, fans, crushers, compressors, blowers, hoists, etc). However, I want to validate these values with a book or any reference.

One practical way is to use the nameplate of the equipment or perhaps to measure the current directly.
