13、hStandard specifies requirements for design, construction, safety, performance, acceptance testing and marking of two classes of unpowered rope storage reels, used for the stowage of wire, natural fibre or synthetic fibre ropes for ships. 2 Definitions For the purposes of this BritishStandard, the t

14、erms and their definitions given in BSMA30 apply. Terms particularly applicable to this British Standard are defined as follows. 2.1 nominal size the nominal size of a rope storage reel is the rope capacity expressed in metres. The nominal size should always be quoted together with the diameter and

15、type of rope to be stored on the rope storage reel NOTE 1The range of nominal sizes covered by this standard are listed in Table 1, column1 and Table 2, column1. NOTE 2The nominal sizes of rope storage reels in Table 1 and Table 2 have been selected from the R10 series of preferred numbers (seeBS204

16、5). 2.2 class A rope storage reel a reel having single reduction gearing, of plate side construction, for wire rope of30mm diameter and above or for fibre rope of80mm diameter and above 2.3 class B rope storage reel a reel having no reduction gearing, of angle frame or plate side construction, for w

17、ire rope up to and including28mm diameter or for fibre rope up to and including76mm diameter Table 1 Wire rope reel design data Table 2 Fibre rope reel design data 3 Design and construction 3.1 Rope storage reels.

19、 than12times the wire rope diameter or four times the fibre rope diameter to be stored thereon. Manufacturers recommendations for synthetic fibre bending ratios should be observed. 3.3.2 The flange height shall be such that it will project at least2.5rope diameters beyond the outermost layer when th

20、e rope is fully and evenly reeled on the drum. 3.3.3 The drum length shall be such that the rope can be fully accommodated in not more than ten layers, the complete length of the rope being evenly reeled. The length of the drum should be not less than11rope diameters. 3.4 Crank handles 3.4.1 All ree

21、ls shall be supplied with two portable crank handles. 3.4.2 The crank radius shall be between300mm and450mm. 3.5 Drum brake 3.5.1 The rope storage reel shall be fitted with a drum brake capable of preventing the reel from paying out under the weight of the rope. 3.5.2 A ratchet or pawl mechanism may

22、 also be fitted. 1 2 3 4 Nominal size (See2.1) Rope capacity (See3.3.3) Wire rope diameter (SeeBS365) Minimum recommended drum diameter (See3.3.1) 125 160 200 250 315 315 a m 125 160 200 250 315 315 mm Up to12 14 to16 18 to28 30 to40 44 to52 56 to60 mm 160 200 315 500 630 800 a For larger diameter r

A licence to use the Kitemark on or in relation to a product will be granted to any manufacturer or producer who demonstrates that he can and will be able con

40、sistently to make that product to a specified British Standard. His capability of doing so is initially assessed by inspection of his production process, quality control organization and test facilities, and by independent testing of a sample of the product against all the criteria of the relevant s

41、tandard. The licensee is required to accept, and to operate in accordance with, a BSI scheme of supervision and control which identifies the tests to be carried out during manufacture and on the completed product, and specifies the frequency of such testing. BSI carries out unannounced inspection vi

42、sits to the manufacturers works and audit testing of the product, and may withdraw the licence for any failure of the manufacturer to comply with the relevant standard or with the requirements of the scheme of supervision and control. The presence of the Kitemark on or in relation to a product is an

43、 assurance that the goods have been produced under a system of supervision, control and testing, operated during manufacture and including periodical inspection of the manufacturers works in accordance with the certification mark scheme of BSI.
