Price based on 1 page Foreword ISo (the International Organization for Standardization) is a worldwide federation of national standards bodies (iSO member bodies). The work of developing International Standards is carried out through ISO technical committees. Every member body interested in a subject for which a technical committee has been authorized has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with iso, also take part in the work. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISo Council. International Standard 2374 was developed by Technical Committee ISO/TC 96, Cranes, lifting appliances and related equipment, and was circulated to the member bodies in February 1983. It has been approved by the member bodies of the following countries : Australia Finland Netherlands Austria France Norway Belgium Germany, F.R. Poland Brazil India United Kingdom China Israel USSR Czechoslovakia Italy Egypt, Arab Rep. of Korea, Dem. P. Rep. of No member body expressed disapproval of the document. International Organization for Standardization, 1983 Printed in Switzerland INTERNATIONAL STANDARD ISO2374-1983 (E) Lifting appliances - Range of maximum capacities for basic models Scope and field of application 3 Range of maximum capacities for basic models This International Standard sets forth the recommended range ofmaximum capacitiesofcranesfrom0,1to1000t. The range of maximum capacities should conform to that listed in the following table. This International Standard applies to all types of cranes.
