These hazards are specific to reel machines for irrigation. The hazards that are common to all the agricultural machines (self-p
21、ropelled, mounted, semi-mounted and trailed) will be dealt with in a standard currently in preparation (prEN 1553). 1 Scope This standard specifies safety requirements and their verification for the design and construction of reel machines for irrigation including self-propelled machines. It describ
22、es methods for elimination or reduction of risks which need specific requirements for reel machines for irrigation. In addition, it specifies the type of information on safe working practices to be provided by the manufacturer. The list of significant hazards dealt with in this standard is given in
23、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 primarily to machines which are manufactured after the date of issue of the standard. 2 Normative references This European Standard incor

28、nitions given in EN 292-1:1991 and EN 292-2:1991 apply together with the following: 3.1 reel machine type of traveller irrigation machine featuring a stationary structure with a reel, coiling a hose which carries irrigation water to, and drags, a travelling cart, upon which is affixed the emitting s
29、ystem, 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 from 10 m 3 /h to 100 m 3 /h, and their nozzle diameter from 10 mm to 40 mm. 3.3 coiling one of the actions performed by the reel machine
30、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 field. When the irrigation gun reaches the machine, the coiling is completed and the machine stops 3.4 guiding system lateral guiding d
31、evice 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 the even layering of the hose 3.6 sweeping zone envelope of the different positions of the turret corresponding to its different p

33、ot 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 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 adjust
34、ment 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) 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
35、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 platform (vertical distance between the ground or the platform and the lowest rotating part of the irrigation gun). This requirement
36、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 range; when the irrigation gun is fitted with a guard providing a safety distance in accordance with EN 294:1992. 4.3 Guiding syst
37、em 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 guiding system and the frame of the machine shall be prevented by fixed guards according to EN 953 or by the framework of the mach
38、ine 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 between the guiding system and the frame of the machine shall be prevented by fixed guards according to EN 953 or by the fram
39、ework 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 953. 4.4 Spool If the rotation of the drum generates crushing or shearing points between the spool and the machine frame, suc
40、h 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 opening) side wall without any prominent feature including the water delivery pipe between the axis of the drum and the hose. Mach
41、ines equipped with hose speed selector shall be fitted with: BS EN 908:1999+A1:2009EN 908:1999+A1:2009 (E) 7 a device which allows for the removal of tension from the hose before changing gear; or a device which enables the operator to change gear under tension. 4.5 Stability Any means needed to ens
42、ure 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 stable when resting on a slope of 8,5 in the following conditions: without using the additional means to ensure stability; ho
43、ses 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, sh
44、all be at a minimum distance of 5 m away from the machine. 4.6 Orientation of the turret If applicable, turrets shall be lockable in both working and transport positions. The centre of gravity of the mobile part shall be located at less than 0,20 m from its rotational axis when the hoses are filled
45、of water. Failing this, the rotation shall be ensured by a hold-to-run control device located outside from the sweeping zone. 4.7 Hydraulic lifting When hydraulic lifting systems are used, they shall be fitted with antifall devices to ensure a falling speed of less than 0,1 m.s -1in the event of rup
46、ture of a hydraulic pipe. 4.8 Accessories An appropriate housing shall be provided on the machine for the storage of specific tools. 4.9 Transport The hose reel or machine shall be provided with means for attaching the hose to the machine during transportation. 5 Verification of safety requirements
47、and/or measures Dimensions, where given, shall be verified by measurements. Controls shall be verified by a functional test and positional measurements; guards by functional tests.

48、ns and information on all aspects of maintenance and the safe use of the machine shall be provided in the instruction handbook. It shall comply with 5.5 of EN 292-2:1991. In particular, the following points shall be emphasized: a) the hazards that may occur when adjusting the machine while it is ope
49、rating; b) the hazards due to any lack of stability caused by steep slopes or difficult working conditions; c) the risk of touching overhead power lines with the machine or the water jets; d) dangers due to the hazard of instability of the hose reel during operation and the use of jacks or supporting wheels where necessary; e) the speed of rotation if it is more than 1 rad.s -1 ; f) the hazards of unforeseeable rotation of the drum around its vertical axis; g) the unrolli
