BS4073:1966 iv BSI 04-2000 This British Standard has been prepared under the authority of the Colliery Requisites Industry Standards Committee, with the purpose of stating principles of design and specifying certain major components of mineral haulage rolling stock (60200ft 3capacity), gene
25、rally known as “mine cars”, in coal mines in the United Kingdom. The specification is complementary to BS3237 (which deals with light and medium rolling stock of capacity below60ft 3 , for mineral haulage in mines) and it is designed to cover a range of heavy rolling stock incorporating suspension g
26、ear, couplers and buffing gear, and wheel and axle assemblies (embodying taper roller bearings); also ancillary equipment such as tippler and retarder brackets, and brakes. Drop bottom and side tipping types, and special purpose vehicles such as containers operating on restricted circuits, are exclu
27、ded. However, it is recommended that components from this standard be utilized for such vehicles, where applicable. Comprehensive dimensions for a range of21 cars are given inTable 1 and the preferred sizes representing general colliery usage in the U.K.are indicated. In preparing standard requireme
28、nts for the complete vehicle, care has been taken to avoid detail that would unnecessarily restrict design. Hence, the specification for components deals mainly with design principles and basic requirements essential to a product of good quality. No provision is made for nipples for the pressure gre
29、asing of wheels (Figure 4 andFigure 5); it is modern practice to grease the bearings during original assembly and only to renew the grease at planned maintenance periods. Attention is drawn to the serious hazard inherent in the use of aluminium or aluminium alloy in incendive atmospheres, particular
30、ly in mines in which the use of lamps or lights, other than permitted lights, is unlawful. NOTEWhere metric equivalents have been given (seeAppendix D), the figures in British units are to be regarded as the standard. The metric conversions are approximate. More accurate conversions should be based
31、on the tables inBS350, Part 1, “Conversion factors and tables”. A British 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 f
32、rom legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i to iv, pages1to 40, 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 amendme
33、nt table on the inside front cover.BS4073:1966 BSI 04-2000 1 1 Scope This British Standard provides specification of materials, basic design requirements and constructional details, including specifications for individual components, for heavy rolling stock of “solid bottom” design, with capacities
34、within the range60to200ft 3 , having approximate tonnage capacities of1 1 / 2to 5tons of coal, or3to10 tons of stone (seeClause2). Vehicles are of the type employing resilient suspension and having loose wheels incorporating precision bearings. The dimensions and other requirements of the main compo
35、nents are presented on a basis of alternatives permissible for each size/load combination, so that selection may be made to produce an overall design, made up of standardized parts, as required for particular purposes or service conditions. This standard provides for rolling stock designed to carry
36、different kinds of bulk materials, such as metalliferous ores, as well as for rolling stock primarily designed for coal or stone.BS4073:1966 2 BSI 04-2000 Part 1. General requirements 2 Capacities The standard provides for the following nominal capacities of rolling stock: NOTECoal payload equivalen
37、ts are based on a nominal40ft 3to the ton and stone at20ft 3to the ton, assuming “flush” loading in each case. The average weight/bulk ratio of different materials varies and the exact payload of the vehicle should be determined from figures obtained locally. 3 Vehicle types and dimensions Table 1 p
38、rovides alternative dimensions for the vehicle, for each nominal capacity, to afford satisfactory selection for a given requirement. 4 Designation (car reference) Designation of vehicles shall be on the following basis, to provide car reference numbers: i) The number of this British Standard, i.e.BS
39、4073, followed by: ii) The appropriate car serial number from column(1) ofTable 1, followed by: iii) The relevant estimated capacity (ft 3 ) from column(2) ofTable 1, e.g.BS4073/11/102. 5 General finish and protective coating Unless otherwise specified by the purchaser, a all surfaces of the car sha
40、ll be cleaned and have the scale removed; andb, two coats of white paint, approved by the purchaser, shall be applied outside, and one applied inside, the body. 6 Inspection The manufacturer shall maintain and make available all relevant records of quality control, inspection and testing of the item
41、s concerned (including calibration certificates for testing machines) and, if requested, shall supply copies to the purchaser or his representative. 7 Marking Marking additional to that specified inClause4 shall be at the option of the manufacturer or, alternatively, as agreed between manufacturer a
42、nd purchaser.

Designation Details for compiling the designation, including car serial number are stated inClause4. 2. Rail gauge Fo
47、r any car specified for a rail gauge of2ft0 in or2ft6in, a rail gauge of2ft3 in may be substituted, provided that the body width exceeds the rail gauge by at least9 in and not more than12in. Where any car is required to run on track having a rail gauge which is not included inTable 1, the width of t
48、he underframe should be suitably modified. 3. Body dimensions When designing cars for a capacity between the standard values given inTable 1, the designer should use the dimensions of the nearest suitable standard design, and should adjust the depth only in order to provide the capacity required. Wh
49、ere increase in depth is necessary, this should not exceed4 in, to ensure stability of the car. For the carriage of stone or ores, the standard dimensions of width and length may be used with a reduced dimension for depth, possibly one-half. Where the top edge of the car body is bent inwards to accommodate external top edge stiffeners, the car capacities as given in Table 1 will be affected. 4. Height The height given in column7 is the distance from rail level to the top of the car when the car is unladen. 5. Leng
