4、ion03.10 DIN EN 13448:2010-02 2 A comma is used as the decimal marker. Start of validity This standard takes effect on 1 February 2010. National foreword This standard includes safety requirements. This standard has been prepared by Technical Committee CEN/TC 144 “Tractors and machinery for agricult

5、ure and forestry” (Secretariat: AFNOR, France), Working Group WG 3 “Mobile machines and trailers”. The responsible German body involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Section Landtechnik. Amendment of the European Machinery Direc

6、tive has made it necessary to review the previously valid standard, EN 13448:2001, 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”, Dir

7、ective 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 inter-row mowing units that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate

8、 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 Directi

9、ve (“presumption of conformity”). The European Standards referred to in clause 2 of this document have been published as the corresponding DIN EN or DIN EN ISO Standards with the same number. This standard makes reference to documents which were valid as of the publication of the European standard.

10、Since then, the standards EN 292-1:1991 and EN 1070:1996 have been superseded by EN ISO 12100-1:2009, EN 292-2:1991 has been superseded by EN ISO 12100-2:2009, EN 294:1992 has been superseded by EN ISO 13857:2008, EN 754 has been superseded by EN 745+A1:2009, EN 1553:1999 has been superseded by EN I

11、SO 4254-1:2005 and EN ISO 3457:1995 has been superseded by EN ISO 3457:2008. Amendments This standard differs from DIN EN 13448:2002-04 as follows: a) The instruction handbook and the technical documentation describing the machine prepared by the manufacturer for the information of potential users h

12、ave been modified with regard to noise (7.1). b) Subclause 7.2 “Marking” has been modified. c) Revision of Annex ZA (informative) “Relationship between this European Standard and the Essential Requirements of EU Directive 98/37/EC”. d) Inclusion of Annex ZB (informative) “Relationship between this E

28、n This document is a type C standard as stated in EN 1070. The machinery concerned and the extent to which hazards are covered is indicated in the scope of this standard. These hazards are specific to inter-row mowing units. The hazards that are common to all agriculture machines (self-propelled, mo

29、unted, semi-mounted and trailed) are dealt with in EN 1553:1999. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been

30、designed and built according to the provisions of this type C standard. 1 Scope This European Standard specifies the safety requirements and test methods for the design and construction of inter-row mowing units with vertical spindles mounted on grass cutting machines such as flail mowers, used in a

31、griculture, forestry and landscaping to cut the grass in the area between two successive obstruction. It describes methods for elimination or reduction of risks arising from their use. In addition, it specifies the type of information on safe working practices to be provided by the manufacturer. Thi

32、s standard is not applicable to rotary mowers and flail-mowers which are covered by EN 745. Environmental aspects have not been considered in this standard. This European Standard is not applicable to inter-row mowing units which are manufactured before the date of publication of this document by CE

33、N. 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 publications are listed hereafter. For dated references, subsequent amendments to or re

34、visions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

38、tical spindles equipped with pivoting boom, which allows grass cutting in the area between two successive obstructions (e.g. trees, posts, etc.) (see Figure 1) 3.2 pivoting boom device which allows the inter-row mowing unit to perform lateral translation movements parallel to the ground, thus allowi

39、ng cutting within the area between two successive obstructions which would not be possible using fixed mowing machines (see Figure 1) 3.3 sensor device controlling boom movement, mounted forward of the inter-row mowing unit NOTE The device may be formed of a metal rod which, when pushed backwards on

40、 encountering an obstruction, sends a command causing the boom to retract. Immediately after the obstacle has been passed, the sensor returns to its original position, and the boom returns to the working position. 3.4 target device which registers the number of impacts of objects propelled by the mo

42、 292-1 and EN 292-2 and are considered applicable to machines covered by the standard are listed in annex A. Annex A also indicates the hazards which have not been dealt with. 5 Safety requirements and/or measures 5.1 General Machinery shall comply with the safety requirements and/or protective meas

43、ures of this clause. In addition, the machine shall be designed according to the principles of EN 292 for hazards which are not dealt with by this standard 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

44、, the machine shall comply with the requirements of EN 1553:1999 and EN 745 and with Tables 1, 3, 4 and 6 of EN 294:1992. 5.2 Protection of cutting elements The machine shall be equipped with an imperforate blade enclosure which fully covers the cutting elements, capable of ensuring a safety distanc

45、e of at least 50 mm beyond the external trajectory of the cutting elements and which extend at least 3 mm below the plane of the blade tip circle (see Figure 2). The blade enclosure shall be free of protrusions and sharp edges and, in the case of a mechanical pivoting boom, the device which allows t

46、he unit to rotate idly when it encounters an obstruction shall be designed, so that the rotary movement of the cutting elements is not imparted to the blade enclosure itself. The blade enclosure and the parts of the machine ensuring the guarding shall withstand a vertical downwards load of 1200 N, a

47、nd, in order to resist to the forces generated when the blade enclosure hits an obstruction, shall additionally withstand the following horizontal loads: 600 N for machines intended to be used with a tractor whose maximum power as given in the instruction handbook is less or equal to 37 kW; 1 000 N

48、for the other machines. These requirements shall be checked by the test procedure and the test acceptance defined in EN 1553:1999, annex B. 6DIN EN 13448:2010-02 EN 13448:2001+A1:2009 (E) Dimensions in millimetres Key 1 Ground 2 Blade tip circle 3 Blade enclosure Figure 2 5.3 Hose protection In the

49、case of hydraulically or pneumatically operated inter-row mowing units, pipes and hoses shall be fitted, assembled and if necessary retained to minimise contact with hot surfaces, friction and other unintentional exterior damage. Visual inspection of hoses and fittings shall be possible except those located inside frames.
