International organizations, govern- mental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Comm

10、avelling cranes and portal bridge cranes based on the number of operating cycles to be carried out during the expected life of the ap- pliance and its mechanisms, and a load spectrum factor which represents the nominal state of loading. 2 Normative reference The following standard contains provision

13、classified in accordance with IS0 4301-1. Guidance as to typical classifications for overhead travelling cranes and portal bridge cranes in relation to usage is given in table 1. Where the class of utilization and state of loading are not known, the classification should be regarded as a minimum. -1
