The work of preparing International Standards is normally carried out through ISO technical committe
11、es. Each member body interested in a subject for which a technical committee has been established 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. ISO collaborates closely with the Inte
12、rnational Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Sta
13、ndards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subje

ISO shall not be held responsible for identifying any or all such patent rights.ISO 7133 was prepared by Technical Committee ISO/TC 127, Earth-moving machinery, Subcommittee SC 4, Terminology, commercial nomenclature, classification and ratings.This third edition cancels and rep

This tractive effort
36、can be developed by the scraper itself, by another scraper temporarily or permanently connected, or by a pushing tractor. The tractive effort for a towed scraper is supplied by the towing machine.NOTE 2 Elevating scrapers have a powered mechanism fixed to the scraper bowl to assist in loading materi
