11、heffieldun sheffieldun, na, Fri Dec 01 13:49:20 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS 5827:1979 ii BSI 02-1999 Foreword This British Standard has been based on performance requirements rather than on requirements for materials. The performance requirements in this standard are based on the r
12、esults of tests carried out on various mobile patient-lifting devices that were known to have given satisfactory service. A wide variety of accessories is available for use with lifting devices and they cover a large range of operations. The advantages and disadvantages of the various systems are co
13、nsidered to be a matter for nursing, medical and paramedical advisers. The committee responsible for this standard considered that, for the purpose of this specification, the variety of circumstances and environments in which lifting devices are used precludes their specification in detail. A Britis
14、h Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front
15、cover, an inside front cover, pages i and ii, pages 1 to 6, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover. Licensed Copy: sheffieldun sheffie

44、t on the raising and lowering mechanism as a separate assembly provided it is subjected to stresses equal to those to which it would be subjected when assembled in a lifting device carrying the safe working load. In this case the mechanism should be re-assembled in the lifting device before carrying
45、 out the test specified in 8.3. 8.2 Load raising and lowering test 8.2.1 The lifting device shall satisfactorily raise a test load equivalent to 125 % of the safe working load. The test load shall be raised from the lowest operating position to an upper position defined as follows. a) If, when the d
46、evice is in use, raising of the load is effected by changing the angle between the mast and the jib, the upper position shall correspond to the jibs being at an angle of 60 above the horizontal. b) In all other cases the upper position shall be the highest operating position. 8.2.2 The load, as deta
47、iled in 8.2.1, shall remain at the high position for a period of 15 min and during this period it shall not fall from its initial position by more than 3.0 mm. 8.2.3 A load equivalent to the safe working load shall be raised from the lowest operating position to the highest position as defined in 8.
48、2.1. The maximum force that the operator needs to exert shall be measured and shall not exceed 120 N. 8.2.4 With the safe working load suspended at the highest position, the release device shall be operated and the load allowed to fall to the lowest position. Where the descent rate is not controlled
49、 by the direct physical effort of the operator, the rate of fall shall not be more than 108 mm/s. If a staged or stepped release control is provided, this test shall be carried out with the release device moved to the initial position intended to allow the lowering of a patient. 8.3 Stability tests 8.3.1 Stability tests shall be carried out by placing the lifting device carrying the safe working load on an inclinable surface and measuring the angle to which the surface has to be inclined to cause the lifting device to become unstable. 8.3.2 The load shall be so
