4、2011-02 2 A comma is used as the decimal marker. Start of validity This standard takes effect on 1 February 2011. National foreword This standard includes safety requirements. This standard has been prepared by Technical Committee CEN/TC 144 “Tractors and machinery for agriculture and forestry” (Sec
5、retariat: AFNOR, France). The responsible German body involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Working Committee NA 060-16-01 AA Traktoren of Section Landtechnik. Representatives of interested parties contributed to this standard.
6、 This standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Directive”, Directive 2006/42/EC, and which apply to machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of complian
7、ce 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 Directive (“presumption o
8、f conformity”). The European Standards referred to in Clause 2 and in the Bibliography of the EN have been published as the corresponding DIN EN or DIN EN ISO Standards with the same number. Where the International Standards referred to are not also DIN ISO Standards, there are no national standards
9、 available Amendments This standard differs from DIN EN 12525:2000-03 and DIN EN 12525/A1:2006-10 as follows: a) Clause 1, Subclauses 4.5.1, 7.1.5 and Table A.2 have been technically revised; b) Clauses 2, 3 and 4, Subclause 7.2 and Table A.1 have been slightly modified; c) Annex ZA has been editori

30、e scope of this standard. #This document is a type C standard as stated in EN ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are covered are indicated in the scope of this document. When provisions of this type C standard are different f
31、rom 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 Standard$ specifies safe
32、ty requirements and their verification for the design and construction of front loaders designed to be mounted on agricultural and forestry wheeled tractors (as defined in the #Directive 2003/37/EC$). Hazards related to mounting the lifting arms to the frame mounted on the tractor, and also hazards
33、related to devices for mounting attachments to the arm are covered. Hazards related to mounting the frame to the tractor (carried out by the dealer of the loader and/or of the tractor), the mounted attachments and hazards due to loss of mechanical strength of the structure are excluded. !deleted tex
34、t“ Hazards related to the transport of passengers are not covered. This #European Standard$ describes methods and requirements for the elimination or reduction of risks which need specific requirements to front loaders. In addition, it specifies the type of information on safe working practices to b
35、e provided 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. #This European Standard is not applicable to front loaders which are manufactured before the date of its publication as

44、icant, which are not dealt with by this document.$ 4.1 Mounting of the front loader on a tractor 4.1.1 Intended use The front loader manufacturer shall state which tractors are suitable for the mounting and use with the front loader taking into account the specific technical characteristics of the t
45、ractor and the intended use of the combined unit. 4.1.2 Stability of the combined tractor/front loader The stability of the combined tractor/front loader is dependent on the range and capacity of the attachment, the arrangement of the front loader on the tractor together with the type of tractor. Im
46、provements in stability can be achieved by fitting a counterweight or ballasting the rear wheels and observing limits to driving and operating conditions. For further guidance see Annex B.

48、 provided to support the dismounted lifting arms when stored on the ground. They shall: be so designed that the strength of the structure is able to hold the weight of the lifting arms and of the heaviest allowable attachment under the conditions specified in 4.2.2; have a supporting surface area wh
49、ich exerts a ground pressure of not more than 400 kPa. This requirement shall be met with any allowable attachment in the lowered position; have a locking device to prevent inadvertent lowering and creation of drawing-in or trapping hazards at the supporting devices themselves; be available at any time when dismounting the lifting arms. They shall be attached to the lifting arms or stored separately from the front loader somewher
