The work of preparing International Standards is normally carried out through ISO technica

10、l 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 organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely wit

28、 4.7.4.2 Stress calculationThe stress calculation of the mechanical parts is based on the following:a) the drum load on the winch: in this case, the allowable calculated stresses based on simple theoretical elastic limit of any part of the winch shall not be greater than 0,4 times the 0,2 % proof st

29、ress of the material;b) the maximum torque of the motor corresponding to the most severe working conditions: in this case, the allowable calculated stresses based on simple theoretical elastic limit of any part of the winch shall not be greater than 0,9 times the 0,2 % proof stress of the material.N

30、OTE For the winch equipped with a torque limiter, the setting value by the torque limiter.4.3 Direction of motion of operating control deviceThe direction of motion of the operating control devices shall be such that the load is raised by clockwise movement at a hand-wheel or crank-handle, or altern

31、atively movement of a hand-lever towards the operator.Whatever the form of motive power, the operating control device shall be arranged to return to the braking position automatically when the operator releases the control.Reference should be made to the ILO Code of practice on Safety and health in

32、dock work.The control stations shall be arranged such that the operator can observe the operating area of the lifting appliances and the load being lifted.

33、n and deceleration shall have a mean value of not more than 3 m/s2.4.5 Braking4.5.1 Winches shall be provided with an automatic braking system which operates when bringing the operating control device to zero, or to the braking position, and also when there is no power on the winch.4.5.2 The braking

34、 system shall be capable of arresting and holding a load at least 1.5 times the nominal load.Means shall be provided for lowering the load in the event of power failure.4.5.3 Winches with a declutchable drum shall be provided with a locking device or a brake on the drum capable of preventing rotatio

35、n of the drum.When a brake is required to hold the load, this shall be specified by the purchaser.4.5.4 The braking system shall be such as not to induce an excessive shock load.4.6 Drum design4.6.1 For all operating conditions, the distance between the top of the wire rope on the drum and the outer

36、 edge of the drum flanges shall be at least 2,5 times the diameter of the wire rope.NOTE This requirement only applies to drums not fitted wire rope guards to prevent over-spilling of the wire rope.4.6.2 The length of rope reeling off of the drum shall be appropriate to any operating positions withi

37、n the design working range of the lifting appliances and in any case not less than three turns of rope remaining on the drum.4.6.3 Rope shall be capable of reeling onto the drum evenly and if necessary, coiler or other device may be fitted. The length of the rope drum shall be such that the rope wil

38、l reel onto the drum in not more than three layers, but it is recommended that, where practicable, the rope should reel onto the drum in a single layer. The rope may reel up onto the drum in more than three layers if either one of the following requirements is met:a) the coiler is fitted;b) the drum

39、 has rope groove;c) the reeling angle is restricted up to 2.4.6.4 The diameter of the drum shall be not less than 18 times the diameter of the wire rope, which for design purposes only shall conform to ISO 2408, Group 3, Class 6 37, IWR. Other grades and constructions may be used in service.4.7 Warp
