9、) Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards 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
10、 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 International Electrotechnical Commission (IEC) on all matte
11、rs of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This doc
12、ument was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). 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
13、such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents). Any trade name used in this document is information given for the convenience of users and

26、4:2016(E) 4.2 The drum length shall be such that the rope in effective working length can be wound on fully, in not more than three layers, while the rope can be wound on fully, in not more than five layers. 4.3 The drum diameter shall be not less than 14 times the rope diameter given in Table 1. 4.
27、4 The flange height shall be such that it will project at least 1,5 times the rope diameter beyond the outermost layer of the rope. 4.5 Double drum winches intended for double flight accommodation ladders shall be fitted with a suitable device to allow independent holding, hoisting or lowering of ea
28、ch flight. 4.6 The winch shall be provided with a device capable of holding the drum at 1,5 holding load. For powered winches, such device shall automatically operate when the drive is being shut off or if the power fails. Manual lowering and hoisting of the accommodation ladder shall be possible. A
29、 self-braking worm gearbox (or equivalent) may be considered a holding device if agreed between the purchaser and the manufacturer. 4.7 For design purposes, the drum shall be based on the use of 6 37 galvanized steel wire rope with fibre core of 1 770 N/mm 2tensile grade, as specified in ISO 2408. W
30、ire rope diameters are listed in Table 1. This requirement does not preclude the use of other types of rope in service. In every case, the safety factor of the rope shall be not less than five in relation to the holding load as specified in ISO 5488:2015, 6.1.3. NOTE Attention is drawn to the possib
31、ility of national authorities requiring a safety factor of more than five. 4.8 The winch shall be designed to ensure that all bearing surfaces and corresponding sliding and rotating component parts of the winch are lubricated during operation. 4.9 Stresses in component parts of the winch being acted
32、 upon with the drum load and holding load shall not exceed 0,4 times the proof stress of the material. 4.10 The winch shall be fitted with a local emergency stop. 4.11 Powered winches shall also be also provided with manual drive. 4.12 Winches shall be provided with safety precautions to protect the
33、 operator against the possibility of being struck by a revolving crank handle. 4.13 Electrical equipment of winches shall be installed in accordance with IEC 60092-401. 4.14 Winches shall not be made of asbestos-containing material. 5 Characteristics 5.1 The characteristics of the winch shall be as
34、listed in Table 1. 5.2 For powered winches, the nominal speed of hoisting the accommodation ladder shall be not less than 0,05 m/s. 5.3 It shall be possible to continuously overload the drive of the winch by 1,5 times the drum load for 2 min when the accommodation ladder is being hoisted, without ca
35、using failure. ISO 2016 All rights reserved 3BS ISO 7364:2016ISO 7364:2016(E) 5.4 When the accommodation ladder is being hoisted or lowered, the emergency stop of the winch shall be carried out.

38、ion ladder winches. aFor winches working with two ropes, the listed values are the sum of the forces on each rope. bIn column 4, based on a holding load safety factor of five, all values shall be selected in winch load test. cThe rope diameter given in column 4 is used only for static load test of w
39、inches with one rope according to 6.4. dThe rope diameter in brackets means that these values are included in national standard specifications. 6 Acceptance tests (individual) 6.1 General The winch shall be tested as a complete unit, i.e. prime mover, drum, gearing and controls. The results of tests
40、 shall be recorded in the certificate. 6.2 Test without load (factory test) The winch shall be run without load for 10 min continuously, 5 min in each direction. The temperature of bearings shall be checked. 6.3 Drum load test (factory test) 6.3.1 The winch shall be run under drum load through two l
41、owering and hoisting cycles include haul-in operation, the length of the rope paid out being not less than one-third of the drum capacity. The results shall conform to the requirements of 5.2. 6.3.2 Continuously overload the drive of the winch by 1,5 times the drum load for 2 min. The results shall
42、conform to the requirements of 5.3.4 ISO 2016 All rights reservedBS ISO 7364:2016ISO 7364:2016(E) 6.3.3 When the accommodation ladder is being hoisted or lowered, the emergency stop of the winch shall be carried out once. The results shall conform to the requirements of 5.4. The following shall be c
43、hecked: a) oil-tightness; b) input current or working pressure or hydraulic flow; c) nominal speed; d) presence of abnormal noise; e) correct operation of the control brake. 6.4 Static test under 1,5 holding load A load equivalent to the 1,5 holding load shall be applied, with the rope wound in a si
44、ngle layer on the drum. The holding device shall prevent rotation of the drum when subjected to this load. 6.5 On board test and inspections The winch shall be tested as a part of the complete accommodation ladder unit. The minimum extent of the test shall be as follows: a) twice hoisting the accomm
45、odation ladder up to its full height and lowering it (tested as in 6.3); b) holding a static load for the complete accommodation ladder unit loaded as specified in ISO 5488:2015, 6.1.3. 7 Designation Accommodation ladder winches conforming to this International Standard shall be designated as follow
