This International Standard ap

14、plies to all types of cranes. 2 Definitions For the purpose of this International Standard, the foilowing definitions apply. 2.1 maximum capacity; safe working load: The maxi- mum load to be suspended from the lifting appliance as defined for the particular types of cranes and for the specified cond

15、i- tions with regard to the group classification. For jib-type appliances, the maximum capacity is taken at minimum permissible jib length and radius for the working con- figuration. NOTE - Maximum capacity has many Synonyms such as safe working load, lifting capacity ; however, maximum capacity is

16、preferred. 2.2 basic model: The main version on the basis of which further Versions (modifications) of lifting appliances tan be developed, differing in length of jib and/or tower, type of run- ning gear, rope fall of reeving System, etc., whose maximum capacity is determined by the design calculati

17、on. 3 Range of maximum capacities for basic models The range of maximum capacities should conform to that listed in the following table.
