BS EN 706:1996+A1:2009EN 706:1996+A1:2009 (E) 4 Introduction The extent to which hazards are covered is indic
21、ated in the scope of this standard. These hazards are specific to vine shoot tipping machines. The hazards that are common to all the agricultural and forestry machines will be dealt with in a general standard currently in preparation. Machines shall comply as appropriate with EN 292 for hazards whi
22、ch are not dealt with and especially with annex A of EN 292-2:1991/A1:1995 when EN 292 does not give precise requirements. 1 Scope This standard specifies safety requirements and their verification for design and construction of self-propelled, mounted or semi-mounted vine shoot tipping machines. Th
23、ese mobile machines are used for trimming vineyard and other fruit tress that grow in the same way (trellising plants) and similar applications. Their cutting tools are either: High speed rotative blades (which cut by impact), or Rotative blade and counter blade (which cut by shearing), or Reciproca
24、ting cutting bar (which cuts by shearing). This standard does not apply to: Tipping machines for free standing fruit bushes, Walk-behind pedestrian controlled machines, Machines intended to be mounted on walk-behind pedestrian controlled machines, Hand-held machines. NOTE 1 Machines intended to be m
25、ounted on walk-behind pedestrian controlled machines will be dealt with in the next revision of this standard. This standard describes methods for the elimination or reduction of risks which need specific requirements for vine shoot tipping machines. It does not deal with general hazards, particular
26、ly general hazards related to mobility, including those specific to self-propelled machines. These aspects will be dealt with in another standard produced by CEN/TC 144 (see introduction). In addition, it specifies the type of information on safe working practices to be provided by the manufacturer.
27、 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. NOTE 2 This standard does not deal with: the location and the operation of the controls; the adaptability and the setting up of mounted machines on tra
28、ctors or other vehicles. BS EN 706:1996+A1:2009EN 706:1996+A1:2009 (E) 5 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 incorpor

33、otherwise specified in this standard, the machine shall comply with the requirements of tables 1, 3, 4 and 6 of EN 294:1992. 3.2 Protection whilst handling and during storage A machine whose mass is lower than 40 kg, which can be manually installed, shall be fitted with handles located in such a way
34、 they ensure safe handling and that during this operation the operator does not have any contact with the cutting tools. A machine whose mass is equal to or greater than 40 kg shall be fitted with hooking points to enable the use of lifting equipment. A machine shall either have attachments for susp
35、ending it when the machine is not being used or shall be designed to be stored on supports supplied by the manufacturer. Movable or self-closing (retractable) guards for the cutting tools shall be provided by the manufacturer for when the machine is not in use. BS EN 706:1996+A1:2009EN 706:1996+A1:2
36、009 (E) 6 3.3 Protection against hazards associated with moving power transmission parts To ensure protection against hazards related to accessible moving power transmission parts, the machine shall be fitted with fixed guards (according to 3.22.1 of EN 292-1:1991). When frequent access is foreseen,
37、 the machine shall be fitted with guards needing a tool for their opening. These guards shall remain attached to the machine when opened (for example by means of hinges) and automatically lock in the closed position without the use of a tool. If this type of guard is not used, the machine shall be f
38、itted with: Interlocking movable guards (according to 3.22.4 of EN 292-1:1991); or Movable guards fitted with a device which prevents their opening so long as the parts are moving. 3.4 Protection against unintentional contact with the cutting tools Cutting tools shall be fitted with rigid deflectors
39、 in accordance with figures 1 and 2. All parts of the cutting tools not protected against contact with the operator shall be located at more than 850 mm from the reach zone as shown in figure 3. NOTE Requirements on the strength of the deflectors will be added by the revision of the standard. Dimens

If th
42、is residual projection place does not encroach into the driving station, the machine shall be fitted with a protective grating. This protective grating shall be an integral part of the machine and shall be perpendicular to the rotation plane of the cutting tools. The grating shall extend to a minimu
43、m height of 25 cm on both sides of the tools rotation plane (50 cm minimum total height). Its width shall be at least equal to the cutting width of the concerned cutting tool (see figure 1). The mesh of the grating shall not permit the penetration of a cylinder of diameter greater than 10 mm and sha
44、ll have a maximum length of 20 mm. These requirements do not apply to machines with reciprocating cutting bars nor to machines with rotative blade and counter blade. NOTE Requirements for the strength of the protective gratings will be added by the revision of the standard. 3.6 Protection against br
45、eakage of the cutting tools Rotating parts involved in the cutting action shall be designed and built so that they cannot break or come free as a result of centrifugal force and the pull caused by the way they work, for example in the event of them striking obstacles such as stakes. This requirement
46、 shall be verified using the test method described in 4.2. This requirement does not apply to machines with reciprocating cutting bars nor to machines with rotative blade and counter blade. The maximum rotation speed of the cutting tools shall be fixed by design. In the case of hydraulically powered
47、 tools, this requirement is fulfilled when the driving circuit is fitted with a maximum flow control valve. 3.7 Balancing of the cutting tools Cutting tools working by impact shall be dynamically balanced. 3.8 Locking of lateral movement A machine capable of lateral movement shall be fitted with a m
48、echanical locking device for the transport position. 4 Verification of safety requirements and/or measures 4.1 General Unless otherwise specified, compliance with the safety requirements stated in this standard shall be verified by manual inspection using appropriate measuring instruments. 4.2 Impac
49、t test 4.2.1 Test procedure Attach the cutting tool on a rigid frame by the same means as on the machine and drive it in rotation at the limit speed and at the torque recommended by the manufacturer for normal use.
