The work of preparing International Standards is normally carried out through ISO tech
6、nical 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. ISO collaborates closely
7、 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 2. The main task of technical committees is to prepare International Standards. Draft I
8、nternational 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 some of the elements of this document
9、 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 23206 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcommittee SC 4, Tractors. blankBS ISO 23206:20051Agricultural wheele

11、nd a maximum unladen tractor weight of 7 500 kg. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 front loader detachable unit consisting of lifting arms and fastening devices designed to be mounted on a frame on the front of a tractor and equ
12、ipped with a carriage for mounting various attachments See Figure 1. 2.2 attachment working device to be mounted on and operated with a front loader See Figure 1.

14、 2. Dimensions in millimetres Figure 2 Maximum load capacity 3 Dimensions and clearances The carriage dimensions and the dimensions associated with the attachment shall be in accordance with Figures 3 and 4. For the carriage clearance zones, see Figure 3. For the clearance at the back of the attachm

16、in the right-hand side of the drawing it is necessary that the horizontal dimension that was formerly W 35 mm, in combination with the dimension 720 0 2 mm, be in any case greater than the horizontal dimension 790 mm 2 mm in Figure 4. The sum of the smallest values allowed for dimensions W 35 mm (35
17、 mm itself) and 720 mm (718 mm) is 788 mm just the lower limit of dimension 790 mm 2 mm of Figure 4. In this case, no coupling is possible. Accordingly, horizontal dimension W 35 mm has been replaced by W 38 mm in the corrected Figure 3. BS ISO 23206:2005 4 Dimensions in millimetres Key 1 hook 2 eye
18、let 3 attachment buffer aaThe buffer shall be wide enough (W 790 mm) so that the attachment does not deform the carriage during normal operation.

19、S ISO 23206:2005 6 4 Requirements 4.1 General The front loader manufacturer shall specify the type and capacity of the allowable attachments that can be fitted and safely operated. 4.2 Locking device The locking pin on the carriage as shown in Figure 3 may be placed either inside or outside of the f
20、rame. 4.3 Locking and unlocking Locking and unlocking of the carriage to the attachment may be operated either from the drivers seat or from a place near the locking device. A means of visually verifying that the locking process is completed shall be provided such that it is visible from the positio
21、n where the locking device is operated. 4.4 Clearance zones Clearance zones 1 and 2 according to Figure 3 and the clearance at the back of the attachment as shown in Figure 5 shall be maintained to facilitate the coupling process. 4.5 Mounting height of eyelet to an attachment The recommended distan
22、ce between the base surface and the centre of the eyelet is W 150 mm. See Figure 6.
