25、and operation4.1 The winches shall be equipped with one or two drums. The drum shall be a split drum where two ropes are to be wound on it.2 ISO 2016 All rights reservedBS ISO 7364:2016ISO 7364:2016(E)4.2 The drum length shall be such that the rope in effective working length can be wound on fully,

26、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 1.4.4 The flange height shall be such that it will project at least 1,5 times the rope diameter beyond the outermos

27、t 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 each flight.4.6 The winch shall be provided with a device capable of holding the drum at 1,5 holding load. For pow

28、ered 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 self-braking worm gearbox (or equivalent) may be considered a holding device if agreed between the purchaser and

29、 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/mm2tensile grade, as specified in ISO 2408. Wire rope diameters are listed in Table 1. This requirement does not preclude the use of other types of rope in serv

30、ice.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 possibility of national authorities requiring a safety factor of more than five.4.8 The winch shall be designed to ensure t

31、hat 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 upon with the drum load and holding load shall not exceed 0,4 times the proof stress of the material.4.10 The winch sh

32、all 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 operator against the possibility of being struck by a revolving crank handle.4.13 Electrical equipment of winches shall b

33、e installed in accordance with IEC 60092-401.4.14 Winches shall not be made of asbestos-containing material.5 Characteristics5.1 The characteristics of the winch shall be as listed in Table 1.5.2 For powered winches, the nominal speed of hoisting the accommodation ladder shall be not less than 0,05

34、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 causing failure.

39、 tests (individual)6.1 GeneralThe winch shall be tested as a complete unit, i.e. prime mover, drum, gearing and controls. The results of tests 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

40、. 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 lowering 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 confo

41、rm 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 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, t

42、he emergency stop of the winch shall be carried out once. The results shall conform to the requirements of 5.4. The following shall be checked: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 br

43、ake.6.4 Static test under 1,5 holding loadA load equivalent to the 1,5 holding load shall be applied, with the rope wound in a single layer on the drum. The holding device shall prevent rotation of the drum when subjected to this load.6.5 On board test and inspectionsThe winch shall be tested as a p

44、art of the complete accommodation ladder unit. The minimum extent of the test shall be as follows:a) twice hoisting the accommodation 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 5488:20
