EN 16851:2017 (E) 5 European foreword This document (EN 16851:2017) has been prepared by Technical Committee CEN/TC 147 “Cranes - Safety”, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 2017, and conflicting national standards shall be withdrawn at the latest by July 2017. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. For relationship with other European Standards for cranes, see Annex D. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 16851:2017 (E) 6 Introduction This European Standard is a type C standard as stated in EN ISO 12100. This European Standard has been prepared to provide one means for equipment of cranes to conform to the essential health and safety requirements of the Machinery Directive. The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are covered are indicated in the scope of this document (see Clause 1). 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 designed and built according to the provisions of this type C standard. SIST EN 16851:2017



EN 16851:2017 (E) 7 1 Scope This European Standard applies to: — light crane systems, either suspended or free-standing systems; — pillar jib cranes; — wall-mounted jib crane. NOTE 1 For illustration of crane types, see Annex B. NOTE 2 The rated capacity of the light crane systems is generally below 10 t, but the standard is still applicable, if the rated capacity is higher. This European Standard is applicable to cranes and crane systems, whose structures are made of steel or aluminium, excluding aluminium structures containing welded joints. This European Standard is not applicable to cranes covered by another product specific crane standard, e.g. EN 15011 or EN 14985. This European Standard gives requirements for all significant hazards, hazardous situations and events relevant to cranes, when used as intended and under conditions foreseen by the manufacturer (see Clause 4). The specific hazards due to potentially explosive atmospheres, ionizing radiation, operation in electromagnetic fields beyond the range of EN 61000-6-2 and operation in pharmacy or food industry are not covered by this European Standard. This European Standard does not include requirements for the lifting of persons. This European Standard is applicable to cranes, which are manufactured after the date of approval by CEN of this European Standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
