10、prepared under the direction of the Road Engineering Standards Committee and is identical with ISO6483:1980 “Earth-moving machinery Dumper bodies Volumetric rating”, published by the International Organization for Standardization (ISO). ISO6483was produced as a result of international discussions in
11、 which the United Kingdom took an active part. Terminology and conventions. The text of the International Standard has been approved as suitable for publication as a British Standard without deviation. Some terminology and certain conventions are not identical with those used in British Standards; a
12、ttention is especially drawn to the following. Where the words “International Standard” appear, referring to this standard, they should be read as “British Standard”. The comma has been used throughout as a decimal marker. In British Standards it is current practice to use a full point on the baseli
13、ne as the decimal marker. Cross reference. There is no corresponding British Standard for ISO7132 “Earth-moving machinery Dumpers Terminology” (in preparation). The technical committee has reviewed the provisions of this International Standard at the draft stage and has decided that they are accepta
14、ble for use in conjunction with this standard. 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 from legal obligat
15、ions. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages1to 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 in
16、side front cover.BS6113:1981 BSI 11-1999 1 1 Scope and field of application This International Standard specifies a procedure for approximating the volume of typical materials carried in dumper bodies. The volumes are based on the inside dimensions of the bodies and representative volumes on top of
17、the bodies. This rating method is intended to be a consistent means of comparing body capacities; it is not intended to define actual capacities that might be observed in any specific application. 2 Reference ISO7132, Earth-moving machinery Dumpers Terminology 1) . 3 Definitions 3.1 body that portio
18、n of a dumper in which material is carried. See Figure 1 and Figure 2. Surfaces whose function is to protect against personal injury or machine damage are not to be considered as carrying surfaces for this analysis 3.2 bottom dumper dumper which discharges material by opening its bottom 3.3 rear dum
19、per dumper which discharges material in a rearward direction parallel to its longitudinal axis 3.4 side dumper dumper which discharges material in a direction perpendicular to its longitudinal axis 4 Volumetric ratings 4.1 The body shall be positioned as it would be if it were fully lowered on a mac
20、hine on a horizontal surface with all tyres at their recommended pressure. 4.2 Any load retaining or ejecting device shall be positioned to give maximum volumetric capacity. This position must be within the devices normal operating range. 4.3 Boundaries of the struck volume 4.3.1 The interior surfac
21、es of the body bottom, sides, ejection or retention device. 4.3.2 For bodies that have an open end over which material moves when discharged, the volume shall be limited by a plane passing through the rear-most edge of the open end and top rear corners of the side plates or at a slope of1:1extending
22、 upward and inward from the rear-most edge of the open end; whichever is smaller. The planes are defined in4.3.2.1 and 4.3.2.2. Volume computations for open sides can be made in the same manner. 4.3.2.1 The plane, or planes, defined by the intermediate edges. See Figure 3. 4.3.2.2 A plane of1:1slope
23、 from the discharge edge. See Figure 3. 4.3.3 The plane defined by the mean lines. Mean lines are horizontal lines, above which, in a side view of the body, there is an area of the body side equal to the non-bowl side area under the lines. SeeFigure 4. 4.3.4 Vertical planes from the interior surface
24、s of the body sides to the plane of the mean lines. SeeFigure 4. 4.4 Boundaries of the top (heaped) volume 4.4.1 Non-horizontal surfaces, above the upper plane of the struck volume which can retain load. 4.4.2 Plane(s) of2:1 (26,6 ) slope, in and up from the upper edges of the surfaces of 4.4.1 and
25、4.3.4. Planes of 2:1 (26,6 ) slope, in and up, from the edges of upper plane of the struck volume. See Figure 5. It does not mean that all materials will form this angle, but this angle generally expresses best the angle of repose of the usual soils/rocks. 5 Expression of ratings 5.1 Rated capacity
26、of the dumper or trailer body shall be the sum of the struck volume and the top volume. Any published ratings must be within 3% of the volume determined by this procedure. 5.2 Ratings for volumes less than10m 3should be expressed to the nearest0,1m 3while those volumes larger should be expressed to
27、the nearest0,5m 3 . 1) At present at the stage of draft.BS6113:1981 2 BSI 11-1999 Figure 1 Dumper bodyBS6113:1981 BSI 11-1999 3 Figure 2 Types of dumper bodyBS6113:1981 4 BSI 11-1999 Figure 3 Boundaries of the struck volume; planes defined by the intermediate or dischargeedges Figure 4 Boundaries of
