DIN EN 16246:2013-04 EN 16246:2012 (E) 4 Introduction This document is a type-C standard as specified in EN ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations and even
23、ts are covered are indicated in the scope of this document. These hazards are specific to hydraulic backhoes. Hazards that are common to all agricultural machines (self-propelled, mounted, semi-mounted and trailed) are dealt with in EN ISO 4254-1. When provisions of this type C standard are differen
24、t 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. DIN EN 16246:2013-04 EN 16246:2012 (E) 5 1 Sc
25、ope This European Standard, when used together with EN ISO 4254-1 and EN 15811, specifies the safety requirements and their verification for the design and construction of hydraulic backhoes mounted to the three point linkage of a tractor. It describes methods for the elimination or reduction of haz
26、ards arising from the intended use of these machines by one person (the operator) in the course of normal operation and service. In addition, it specifies the type of information on safe working practices (including residual risks) to be provided by the manufacturer. When requirements of this docume
27、nt are different from those which are stated in EN ISO 4254-1, the requirements of this document take precedence over the requirements of EN ISO 4254-1 for machines that have been designed and built according to the provisions of this document. This European Standard, taken together with EN ISO 4254
28、-1, deals with all the significant hazards, hazardous situations and events (as listed in Table 1) relevant to hydraulic backhoes mounted to the three point linkage of a tractor, when they are used as intended and under the conditions of misuse foreseeable by the manufacturer. This European Standard
29、 is not applicable to lifting operations for the movement of unit loads with hooks or other similar devices. Materials connected with excavation activities are not intended as unit loads and their movement is covered by this standard. This European Standard does not give requirements for quick hitch
30、 devices. NOTE 1 An amendment of EN 474-1 is under preparation to deal with this issue. It will be evaluated for inclusion in this European Standard. NOTE 2 Specific requirements related to road traffic regulations are not taken into account in this European Standard. This European Standard is not a
31、pplicable to hydraulic backhoes which are manufactured before the date of its publication as EN. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited ap

39、limits of the backhoe swing pivot 3.8 attachment tool or interchangeable equipment that can be attached to the secondary loading arm, such as a bucket or an inverted bucket, as indicated by the manufacturer 3.9 inverted bucket rearward facing bucket for the excavating, elevating, swinging and discha
40、rging of the material 4 List of significant hazards Table 1 gives the significant hazard(s), the significant hazardous situation(s) and hazardous event(s) covered by this standard that have been identified by risk assessment as being significant for this type of machine, and which require specific a
41、ction by the designer or manufacturer to eliminate or to reduce the risk. Attention is drawn to the necessity to identify any additional significant hazards associated with a specific machine and to provide suitable safety measures. Such additional safety measures are not dealt with by this standard
