The work of preparing International Standards is normally carrie
12、d out through ISO technical 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. IS
13、O collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committ
14、ees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO
15、 shall not be held responsible for identifying any or all such patent rights.

27、2002 All rights reserved 3.4 chippings spreader pushed by tipper truck machine equipped with its own travelling axle and attached to the rear axle of the pushing tipper truck NOTEDelivery roller of the spreader is driven from its travelling axle. 3.5 transport vehicle truck or tractor semi-trailer u
28、nit which carries all the components and provides movement of the chippings spreader during spreading and road transfers 3.6 dumping body bin in form of a box for storage of chippings during operation and transport NOTEThe dumping body supplies the chippings spreading device with chippings. It may b
29、e equipped with either a scraper shield or conveyor (see Figure 1). 3.7 partial partition of dumping body division wall added in order to improve the distribution of loads over the axle and reducing the load on the chippings spreading device 3.8 chippings spreading device spreading unit mounted on t
30、he rear of a tipper truck, and which travels mainly in reverse during work NOTEThe chippings spreading device can be fixed in the place of a tailgate or rear gate of the dumping body. The design of the chippings spreader device is adapted to the vehicle. 3.9 control station assembly which contains t
31、he control and adjustment equipment NOTE 1The control station of a transported chippings spreader is typically installed on a platform, which may be fixed or articulated. The controls fulfil the following functions: on-off control of chippings spreading, adjustment of flow blade with or without indi
32、cator, adjustment of spreading width, and adjustment of dumper tilt. NOTE 2The control station of a self-propelled chippings spreader contains the controls to move the vehicle forward, supply the storage hoppers and spread the chippings. The control station enables the operator to monitor spreading
33、and usually contains: vehicle operation controls with speedometer and revolutions counter for each roller, the control to unhook the towed truck, conveyors, flow blade, bin gates or slanted blades and expandable hoppers. 3.10 power plant assembly which consists of mechanical components (engine, driv
34、e train and driven axles) that contribute to accomplishing the drive function in order to move the chippings spreader during spreading and transfer 3.11 feed system system designed to transport chippings from receiving hopper to spreading hopper NOTEThe receiving hopper receives the chippings discha
35、rged by a truck or semi-trailer. The truck of the semi-trailer is coupled to the chippings spreader by means of a rear-mounted tow hook. One or more conveyors may provide transfer of chippings from this hopper to the spreading hopper. The feed system (Figure 9) is composed of a receiving hopper to e
36、nable supply of conveyors, and the conveyors which transport the chippings from the receiving hopper to the spreading hopper.

Figure 12 NOTEThe spreading hopper may be equip
38、ped with one delivery roller for a fixed width hopper, or multiple rollers or expandable hoppers or moving hoppers. Each delivery roller (1) provided at the hopper base enables regulation of the chippings spreader flow. The roller speed may be automatically controlled by the travel speed of the chip
39、pings spreader. The passage of chippings may be regulated by opening the flow blade (2). A feeder (3) ensures a regular fall of chippings on the ground. The spreading width can be adjusted by bin gates or slanting blades (4) for a fixed width hopper, the position of the expandable hoppers and the op
40、eration of cut-off plates to vary the width of chippings supplied to the spread roller, thereby varying the width of chippings laid onto the road surface. 3.13 dumping body tilt angle angle of tilt of a dumping body bottom in relation to the horizontal, taken along the longitudinal axis of the vehic
41、le ( in Figure 1) 3.14 dumping body slope angle of a dumping body bottom in relation to the horizontal, taken along the transverse axis of the vehicle ( in Figure 1) 3.15 rear overhang of dumping body distance between the tipping axis and the rear of the dumping body cf. Figure 8 3.16 clearance dist
42、ance between the ground and the lowest part of a spreader, taken with the dumping body raised cf. Figure 8 4Description of chippings spreader operation 4.1Extraction or distribution of chippings from the dumper body bottom Extraction is undertaken by a roller or by a conveyor (Figure 2) and enables
43、automatic control of the chippings flow by the forward movement speed of the vehicle. Distribution is undertaken by a roller or by gravity (Figure 3). The flow of chippings does not depend on the feeder element, which requires a constant vehicle speed and a constant angle of inclination of the dumpi
44、ng body bottom. For safety requirements for chippings spreaders, see EN 13020.

The flow blade (or register) enables adjustment of the thickness of the stream of chippings. Adjustment may
46、be undertaken either by using a flow blade or a stop on the bin gates, or by adjusting the speed of the roller or conveyor. 4.3Adjustment of spreading width This adjustment may be undertaken either by the bin gates or by slanting blades (Figure 5). 4.4Automatic control by vehicle speed In order to o
47、btain a constant proportion of chippings on the ground, the roller speed, or the conveyor speed, or the opening of the flow blade may be linked to the vehicle speed unless the latter is kept absolutely constant. 4.5Diffuser A simple diffuser (Figure 6) typically has the following forms: smooth or pa
48、rtitioned; flat or curved. A diffuser with built-in or separate distributor (Figure 7) may be equipped on each side with a folding flap extension so that the spreading width will then be greater than the vehicle width. 5Commercial specifications 5.1Transported chippings spreader 5.1.1Main assemblies These shall be as shown in Figure 1: transporting vehicle; dumping body; chippings spreading device; control station; partial partition. 5.1.2Dimensional char
