6、ry Directive has made it necessary to review the previously valid standard, EN 908:1999, in terms of the essential requirements of the new European Machinery Directive, 2006/42/EC. This standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Directive

7、 Directive 98/37/EC, (valid until 28 December 2009) and the “revised Machinery Directive”, Directive 2006/42/EC, which takes effect on 29 December 2009, and which apply to irrigation machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilit

8、ate proof of compliance with the essential requirements of the directives. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Dire

DIN EN 908:2009-12 EN 908:1999+A1:2009 (E) 4 Introduction The extent to which hazards are covered is indicated in the scope of this

27、standard. These hazards are specific to reel machines for irrigation. The hazards that are common to all the agricultural machines (self-propelled, mounted, semi-mounted and trailed) will be dealt with in a standard currently in preparation (prEN 1553). 1 Scope This standard specifies safety require

28、ments and their verification for the design and construction of reel machines for irrigation including self-propelled machines. It describes methods for elimination or reduction of risks which need specific requirements for reel machines for irrigation. In addition, it specifies the type of informat

29、ion on safe working practices to be provided by the manufacturer. The list of significant hazards dealt with in this standard is given in annex A. Annex A also indicates the hazards which have not been dealt with. Environmental aspects have not been considered in this standard. This standard applies

30、 primarily to machines which are manufactured after the date of issue of the standard. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publ

31、ications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

35、cture with a reel, coiling a hose which carries irrigation water to, and drags, a travelling cart, upon which is affixed the emitting system, which is most often an irrigation gun 3.2 irrigation gun large sprinkler used on reel machines and other systems NOTE The usual flow-rates from guns range fro

36、m 10 m3/h to 100 m3/h, and their nozzle diameter from 10 mm to 40 mm. 3.3 coiling one of the actions performed by the reel machine when irrigating: the reel machine is progressively coiling all the polyethylene hose on the drum, causing the irrigation gun to move regularly across the irrigation fiel

37、d. When the irrigation gun reaches the machine, the coiling is completed and the machine stops 3.4 guiding system lateral guiding device of the hose that permits its steady coiling with joined spirals 3.5 drive system of the guiding system mechanism providing power to the guiding system that ensures

38、 the even layering of the hose 3.6 sweeping zone envelope of the different positions of the turret corresponding to its different possible orientations 1 - Drum of the spool 2 - Turret 3 - Hose guiding system 4 - Irrigation gun Figure 1 DIN EN 908:2009-12 EN 908:1999+A1:2009 (E) 6 4 Safety requireme

39、nts and/or measures 4.1 General The reel machines for irrigation shall comply as appropriate with EN 292 for hazards which are not dealt with and especially with annex A of EN 292-2:1991/A1:1995 when EN 292 does not give precise requirements. Unless otherwise specified in this standard, the machine

40、shall comply with the requirements of prEN 1553:1998 and with tables 1, 3, 4 and 6 of EN 294:1992. 4.2 Irrigation gun The adjustment controls of the irrigation gun that have to be operated during the working (for example adjustment of the sector angle and of the rotation speed of the irrigation gun)

41、 shall be located at a distance less than 1,80 m from the ground or from the access platform, whatever the speed of rotation of the irrigation gun. Irrigation guns with a speed of rotation greater than 1 rad.s-1shall be located at a height equal to or more than 2 m from the ground or from any platfo

42、rm (vertical distance between the ground or the platform and the lowest rotating part of the irrigation gun). This requirement does not apply: when the swivelling range of the irrigation gun is restricted to a maximum of 300 provided that the adjustment platform be located outside the swivelling ran

43、ge; when the irrigation gun is fitted with a guard providing a safety distance in accordance with EN 294:1992. 4.3 Guiding system of hose When the coiling speed of the hose is greater than 0,4 m.s-1, access to crushing and shearing points between the hose and the guiding system and between the guidi

44、ng system and the frame of the machine shall be prevented by fixed guards according to EN 953 or by the framework of the machine using the safety distances according to table 1 of EN 294:1992. When the uncoiling speed of the hose can be greater than 0,4 m.s-1, access to crushing and shearing points

45、between the guiding system and the frame of the machine shall be prevented by fixed guards according to EN 953 or by the framework of the machine using the safety distances of table 1 of EN 294:1992. Access to the drive system of the guiding system shall be prevented by fixed guards according to EN

46、953. 4.4 Spool If the rotation of the drum generates crushing or shearing points between the spool and the machine frame, such points shall be guarded. Satisfactory methods include for example: a guard providing the safety distance according to tables 3 and 4 of EN 294:1992; or a full (without openi

47、ng) side wall without any prominent feature including the water delivery pipe between the axis of the drum and the hose. Machines equipped with hose speed selector shall be fitted with: DIN EN 908:2009-12 EN 908:1999+A1:2009 (E) 7 a device which allows for the removal of tension from the hose before

48、 changing gear; or a device which enables the operator to change gear under tension. 4.5 Stability Any means needed to ensure stability when working (e.g. jacks, supporting wheels) shall be an integral part of the machine. They shall comply with 4.3.2.1.1. of prEN 1553:1998. The machine shall be sta

49、ble when resting on a slope of 8,5 in the following conditions: without using the additional means to ensure stability; hoses full of water and with irrigation gun hooked; in all the directions of the turret around its vertical axis (if applicable); with the axle positioned parallel, then perpendicular to the slope. Any functional outlet of water, associated with the use of the machine, except the possible leakages, shall be at a minimum distance of 5 m away from the machine. 4.6 Orientati
