16、 bodies (ISO member bodies). The work of preparing International Standards is normally carried 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 organiza
17、tions, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO 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 t
18、he ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees 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
19、 some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO15644 was prepared by Technical Committee ISO/TC195, Building construction machinery and equipment. BSI

A chippings spreader is a machine used to spread a layer of chippings on the pavement at a predetermined rate. This In
21、ternational Standard describes the performance characteristics and methods of operation of chippings spreaders and their components. It also provides their definitions and technical characteristics. It includes figures explaining the principles of machine operation and showing the main dimensions re
22、lated to the machines performance.

26、erms and definitions For the purposes of this International Standard, the following terms and definitions apply. 3.1 chippings spreader machine used to spread a layer of chippings on the pavement at a pre-determined rate NOTE A chippings spreader may be defined by its operating principle. Three type
27、s of chippings spreaders may be identified: transported, self-propelled and pushed by tipper truck. 3.2 transported chippings spreader machine equipped with chippings spreading device mounted on the rear of a truck or semi-trailer NOTE The chippings spreading device can be provided with rollers deli
28、very, see Figure 2 a) or spreading, see Figure 3 a). Chippings may be distributed also from the dumping body bottom by gravity Figure 3 b). 3.3 self-propelled chippings spreader self-propelled machine provided with delivery roller cf. Figure 2 a) BSISO15644:20021ISO :44651(2002)E 2 ISO 2002 Ar llith
29、gr seresvde 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 NOTE Delivery roller of the spreader is driven from its travelling axle. 3.5 transport vehicle truck or tractor semi-trailer unit which ca
30、rries 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 NOTE The dumping body supplies the chippings spreading device with chippings. It may be equipped
31、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 the rear of
32、a tipper truck, and which travels mainly in reverse during work NOTE The 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 the control
33、 and adjustment equipment NOTE 1 The 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 indicator, ad
34、justment of spreading width, and adjustment of dumper tilt. NOTE 2 The 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 and usua
35、lly 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, drive train
36、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 NOTE The receiving hopper receives the chippings discharged by
37、 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 enable s
38、upply of conveyors, and the conveyors which transport the chippings from the receiving hopper to the spreading hopper. BSISO15644:20022ISO 46512002:4)E( ISO 2002 r llAithgs reservde 3 3.12 spreading hopper bin supplied by one or more conveyors, which spreads a defined quantity of chippings on the gr
39、ound cf. Figure 12 NOTE The spreading hopper may be equipped 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
40、 automatically controlled by the travel speed of the chippings 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
41、hopper, the position of the expandable hoppers and the operation 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 h

43、rear of the dumping body cf. Figure 8 3.16 clearance distance between the ground and the lowest part of a spreader, taken with the dumping body raised cf. Figure 8 4 Description of chippings spreader operation 4.1 Extraction or distribution of chippings from the dumper body bottom Extraction is unde
44、rtaken by a roller or by a conveyor (Figure 2) and enables 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 veh
45、icle speed and a constant angle of inclination of the dumping body bottom. For safety requirements for chippings spreaders, see EN 13020. BSISO15644:20023ISO :44651(2002)E 4 ISO 2002 Ar llithgr seresvde 4.2 Adjustment of chippings flow The adjustment of chippings flow per unit of width is illustrate
46、d in Figure 4. The flow blade (or register) enables adjustment of the thickness of the stream of chippings. Adjustment may 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. 4.3 Adjustment of spreading width This adjustment may
47、 be undertaken either by the bin gates or by slanting blades (Figure 5). 4.4 Automatic control by vehicle speed In order to obtain 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
48、 latter is kept absolutely constant. 4.5 Diffuser A simple diffuser (Figure 6) typically has the following forms: smooth or partitioned; 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
49、will then be greater than the vehicle width. 5 Commercial specifications 5.1 Transported chippings spreader 5.1.1 Main assemblies These shall be as shown in Figure 1: transporting vehicle; dumping body; chippings spreading device; control station; partial partition. 5.1.2 Dimensional characteristics 5.1.2.1 In transport position The dimensions shown in Figure 8 a) shall be specified: rear projection, (m
