4、dard includes safety requirements. This standard has been prepared by Technical Committee CEN/TC 144 “Tractors and machinery for agriculture and forestry” (Secretariat: AFNOR, France), Working Group WG 3 “Mobile machines and trailers”. The responsible German body involved in its preparation was the
5、Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Section Landtechnik. Amendment of the European Machinery Directive has made it necessary to review the previously valid standard, EN 909:1998, in terms of the essential requirements of the new European Machinery Directive, 20
6、06/42/EC. This standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Directive”, 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
7、to centre pivot and moving lateral types irrigation machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of the directives. Once this standard is cited in the Official Journal of the
8、 European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The European Standards referred to in clause 2 of this document have been published as the corre
9、sponding DIN EN Standards with the same number. This standard makes reference to documents which were valid as of the publication of the European standard.

These hazards are specific to centre pivot and moving lateral types irrigation machines. 1 Scope This standard specifies specific safety require
28、ments and their verification for the design and construction of centre pivot and moving lateral types irrigation machines that are electrically powered. NOTE Figures 1 to 5 give illustrations of these machines. In addition, it specifies the type of information on safe working practices to be provide
29、d 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. Hazards due to the use of the pump associated with centre pivot and moving lateral types irrigation machines are not dealt with.
30、Hazards induced by the use of these machines for pesticide products and liquid fertilizer application are not 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 Nor

35、009-12 EN 909:1998+A1:2009 (E) 5 3 Definitions For the purpose of this standard, the definitions given in EN 292-1:1991 and EN 292-2:1991 apply together with the following: 3.1 centre pivot Irrigation machine constituted of a long length pipe supported by towers equipped with wheels driven by motors
36、, including a fixed point where water and energy arrive. NOTE This irrigation machine can be used either on a complete circle or on a circle quadrant. It can be movable i.e. the pivot point can move from a working position to a new working position, during the movement the watering is stopped. 3.2 p
37、ivot point Fixed point from which the rotation of the whole machine is performed. NOTE It is characterised by a structure fixed on a concrete flagstone leaving the machine free to rotate. Here feeding of water and energy are performed. 3.3 moving lateral Sprinkling lateral built on the same principa
38、l as centre pivot, the displacement of which is lateral (translatory motion). NOTE The control tower receives or pumps the water and receives or produces its own electrical energy. 3.4 control tower In the case of a movable system, tower which initiates the movement of the whole sprinkling lateral.
39、NOTE It can be situated in the centre of the lateral or at one of the ends and be equipped with 2 or 4 wheels, some of them could be driving and possibly steering. 3.5 irrigation gun Large sprinkler with slow motion return used at the end of an irrigation machine generally watering a sector. 4 Requi
40、rements 4.1 General The machines 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 shall comply with the requiremen
41、ts of tables 1, 3, 4 and 6 of EN 294:1992. 4.2 Starting control The switching on control and the displacement control shall be separate. Those manual controls shall be placed on a panel lockable by a key. If the main control panel is not located on the pivot point or on the cart of a moving lateral
42、an additional external circuit breaker shall be positioned at the pivot point or on the cart. DIN EN 909:2009-12 EN 909:1998+A1:2009 (E) 6 4.3 Stopping devices in plot limits In case of danger (road, railway, electrical line, buildings, .), in order to limit the displacement of the centre pivot cove
43、ring a circle quadrant and moving lateral type irrigation machine to the surface intended to be watered, two stopping devices shall be placed on two separate points, each stopping device shall be able independently to stop (or reverse) the displacement. The thrusts used shall have a minimum width ta
44、king into account machine dilatation and misalignment risk, their minimum height from the ground shall be 1 m. In case of danger zone one of the devices shall be a fixed impassable obstacle. 4.4 Alignment guiding The alignment device shall be doubled with a safety device in case of misalignment. The
45、 safety device shall be activated in passive position. In case of breaking of the alignment device, a return spring or other mechanical device shall be able to bring back the machine in safety position. For movable machines, in case of loss of guiding signal or deviation of more than 0,5 m, the mach
46、ine shall stop. 4.5 Stability 4.5.1 Pivot point The fixation of the pivot point shall withstand an horizontal load F = 10 000 N applied to the top of the pivot point (horizontal axis of the elbow) and a reversing moment of Fxh = 40 000 Nm (h is the vertical distance from the application point of F t
47、o the ground). Each anchorage shall be able to withstand half of the load applied by the spray line, the anchorages shall be completely apparent and treated against corrosion. 4.5.2 Span The span stability shall be checked by using the calculation note of prEN 12325-2:1996, annex A. The permissible
48、load in accordance with the elastic limit shall be weighted with the coefficient 1,5 under static conditions. The following loading cases will be considered for a machine with and without water: difference of slope between two consecutive spans = 15 % (see example in figure 1); total slope over seve
49、ral spans or the entirety = 10 % (see example in figure 2); relative angle between two consecutive towers = 15 (see example in figure 3); relative angle between any two towers of the machine = 30 (see example in figure 4); ground clearance H beneath these spans, or beneath the overhang at any point of the installation minimum ground clearance specified by the manufacturer (figure 5); side effort due to track effect = 10 000 N (5 000 N per wheel). The minimum steel wall thick
