The work of preparing International Standards is normally carried out through ISO technical committees. Each member the right to be represented on that committee. International organizations, govern- mental 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. They are approved in accordance with ISO procedures requiring at least 75 % approval by the member bodies voting. International Standard iSO 4301/1 was prepared by Technical Committee ISO/Tc 96, Cranes, lifting appliances and related equipment. This second edition cancels and replaces the first edition (IS0 4301-1980), of which it constitutes a minor revision. Users should note that all International Standards undergo revision from time to time and that any reference made herein to any other International Standard implies its latest edition, unless otherwise stated. @ International Organization for Standardization, 1986 Printed in Switzerland ISO 4301/1-1986 (E) INTERNATIONAL STANDARD Cranes and lifting appliances - Classification -- Part 1 : General Introduction Use of classification 0 2 Classification has two applications in practice, which although Cranes play a part in the handling of materials by raising'and moving loads the mass of which is within their nominal capac related can be regarded as separate objectives. ity.
