BS EN 13448:2001+A1:2009EN 13448:2001+A1:2009 (E) 4 Introduction This document is a type C standard as stated in EN 1070. The machinery concerned and the extent
21、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, mounted, semi-mounted and trailed) are dealt with in EN 1553:1999. When provisions of this type C st
22、andard 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 designed and built according to the provisions of this type C standard. 1 Scope This European Stan
23、dard 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 agriculture, forestry and landscaping to cut the grass in the area between two successive obstructi
24、on. 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. This standard is not applicable to rotary mowers and flail-mowers which are covered by EN 745. Enviro
25、nmental 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 CEN. 2 Normative references This European Standard incorporates by dated or undated reference, provi
26、sions 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 revisions of any of these publications apply to this European Standard only when incorporated in it

30、cifications. 3 Terms and definitions For the purposes of this European Standard, the terms and definitions given in EN 1070 apply together with the following: 3.1 inter-row mowing unit rotary mower with vertical spindles equipped with pivoting boom, which allows grass cutting in the area between two
31、 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 allowing cutting within the area between two successive obstructions which would not be possible usi
32、ng 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 encountering an obstruction, sends a command causing the boom to retract. Immediately after t
33、he 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 mowing unit 3.5 danger zone area surrounding the machine with a radius of 50 m as measured from
34、the centre of the unit Key 1 Blade enclosure 2 Lateral protection Figure 1 Inter-row mowing unit BS EN 13448:2001+A1:2009EN 13448:2001+A1:2009 (E) 6 4 List of hazards The hazards, among those which appear in EN 292-1 and EN 292-2 and are considered applicable to machines covered by the standard are
35、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 measures of this clause. In addition, the machine shall be designed according to the principle
36、s 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, the machine shall comply with the requirements of EN 1553:1999 and EN 745 and with Table
37、s 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 distance of at least 50 mm beyond the external trajectory of the cutting elements and which exten
38、d 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 the unit to rotate idly when it encounters an obstruction shall be designed, so that the ro
39、tary 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, and, in order to resist to the forces generated when the blade enclosure hits an obstructio
40、n, 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 for the other machines. These requirements shall be checked by the test procedure and the
41、test acceptance defined in EN 1553:1999, annex B.

42、s 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. Hydraulic hoses containing fluid with a pressure of more than
43、5 MPa (50 bar) and/or having a temperature over 50 C, and which are located within 1 m of the operator, shall be guarded in accordance with EN ISO 3457:1995, 4.9. Any part or component which may divert a possible jet of fluid can be considered as a sufficient protection device. 5.4 Thrown objects Th
44、e possibility that objects propelled by the rapid rotary action of the cutting elements during operation, which may constitute a hazard and risk of injury to the operator, shall be prevented. Tests shall be performed in accordance with the indications given in clause 6. 5.5 Requirements for pivoting
45、 booms Requirements for the pivoting boom including its strength, mounting, control system and control devices will be added at a future revision of the standard. 5.6 Noise Noise emission from inter-row mowing units shall be measured according to EN 1553:1999, annex D. Noise will be fully dealt with
46、 at a future revision of the standard. BS EN 13448:2001+A1:2009EN 13448:2001+A1:2009 (E) 8 6 Test methods Thrown object test NOTE Round Robin tests will be carried out based on this test method. The results of these tests will possibly indicate the need for the revision of this standard. 6.1 General
47、 test conditions During the tests, the inter-row mowing unit shall be operated at the rotation frequency recommended by the manufacturer, e.g. at a power take-off rotation frequency of 540 min -1 or 1 000 min -1 . All the tests shall be performed using the same safety guard. Adjustable devices which
48、 may influence the efficiency of the safety guard shall be located in the least favourable position. During the tests, the forward travel speed shall not be more than 8 km/h. 6.2 Target The target shall be sited on natural, compact, level land. 6.2.1 Target for a rotary inter-row mower hitched to th
49、e rear of a tractor The target consists of four vertical panels (see Figure 3) which shall comply with the specifications in 6.2.3. Panels 2 and 4 shall be 4 000 mm long. The length of panels 1 and 3 depends on the tractor-mower group. Panel 1 shall be perpendicular to panel 2. Panels 2 and 4 shall be parallel to the longitudinal axis of the tractor. Panel 2 shall be positioned at a distance of 1
