10、bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. 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 organizat
11、ions, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the
12、 ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards 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 th
13、e member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 3730 was prepared by Technical Committee ISO/TC 8, Ships and marine

29、 the purchaser and manufacturer, the rope may be hauled in by anti-clockwise movement at a hand-wheel or crank handle.The direction of motion of the operating devices shall be clearly and permanently marked.Whatever the form of motive power, the operating devices shall, when under manual control, be
30、 arranged to return to the braking or stop position automatically, unless otherwise agreed between the purchaser and manufacturer.4.5 Brakes4.5.1 Automatic braking systemElectric winches shall be provided with an automatic braking system which operates when bringing the operating device to the stop
31、or braking position, and also when there is no power on the winch. The brake shall be capable of holding a load on the hawser of 1,5 times the drum load and of stopping the drum rotation from its maximum speed without suffering damage.For winches of hydraulic or steamdrive, when bringing the operati
