8、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 technical committee has been esta
9、blished 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 matters of electrotechnical standardiza
10、tion. 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 Standards adopted by the technical committees are circulated to the member bodies for votin

38、with of ISO 13852:1996, Tables 1, 3, 4 or 6. 6.1.2 Where a winch rope passes over an idler pulley, provisions shall be made to retain the rope in the groove of the pulley during slack rope conditions. 6.1.3 If the winch operation controls are located such that the operator can reach rope or drum dur
39、ing powered operations of the winch, the rope and winch shall be guarded up to the idler pulley. 6.1.4 Detachable winches shall be designed for easy and safe attachment and removal, including rigid mounted supports, and with a storage position provided, giving stability from tip-over when the winch
40、is detached. A support for a power take-off (PTO) drive shaft disconnected from the tractor power take-off (PTO) shaft shall be provided to prevent contact with the ground. 6.1.5 Machines equipped with fixed and detachable winches, including those with remote controls or fixed controls, shall have O
41、PS guarding meeting the performance requirements of ISO 8084, protecting the operator while sitting in the drivers seat. 6.1.6 Guards and shields to protect the operator and others from winch components that create hazards during normal operation and servicing shall be in accordance with ISO 3457. 6
42、.2 Drum 6.2.1 The ratio between barrel diameter and rope diameter shall not be less than 8. NOTE It is recognized that for some regional applications higher values are used. BS ISO 19472:200676.2.2 The winch shall be designed to prevent the rope from running off over the flanges if the top layer for
43、 any reason reaches above the flanges. Winches with housings that extend 2d beyond the outmost periphery of the flange or the use of kickers and/or crossbars meet this requirement. 6.3 Rope breaking load The static breaking load of the rope installed on a winch used with a protected operator in the
44、cab shall not be less than 1,4 times the rated line pull of the machine/winch system. For all other applications, use a minimum of twice the rated line pull of the machine/winch system. NOTE The static breaking load of new wire rope is given in ISO 3108 according to size and construction. 6.4 Rope f
45、astening 6.4.1 The drum shall be provided with a device for attaching the rope that is designed to avoid rope damage, especially at the attachment point. This device shall meet the requirements of 6.4.2 to 6.4.4. 6.4.2 The device for attaching the rope to the drum should be of the breakaway anchor t
46、ype so that in the event of the load sliding out of control with the winch in free-spool mode, the rope will disengage from the drum. 6.4.3 The device shall be designed to disengage, without any rope on the drum, at less than 0,3 times the maximum rated bare drum line pull. With three turns of rope
47、around the drum, a traction equal to 1,25 times the maximum rated bare drum pull shall be applied to the rope without any disengaging of the device. 6.4.4 The device shall not disengage automatically when the rope is being manually spooled off the drum. 6.5 Brake 6.5.1 The brake system or equivalent
48、 shall automatically be applied within 1 s when the power to the drum is disconnected. A release mechanism may be included to allow free spooling. 6.5.2 The brake system or equivalent shall hold a load equal to at least 1,25 times the maximum pull of the winch without slippage. 6.5.3 The brake syste
49、m or equivalent shall give smooth stopping and release of the drum for all pull conditions up to and including 1,25 times the maximum rated bare drum line pull. 6.6 Controls 6.6.1 The maximum forces necessary to operate manual controls shall not exceed those given in ISO 10968. Out-of-detent positions such as off-free-spool and returning-from-brake shall have a maximum force of 230 N. 6.6.2 The controls shall be so designed and located as to minimize the pos
