ISO 4301-1:2016 establishes a general classification of cranes and mechanisms based on the service conditions, mainly expressed by the following: - the total number of working cycles to be carried out during the specified design life of the crane; - the load spectrum factor which represents the relative frequencies of loads to be handled; - the average displacements.   Additional information for the user: This version uses the cycle - based classification method. If you need to use the time - based classification method please use the 1986 version.
