EN 17067:2018 (E) 4 European foreword This document (EN 17067:2018) has been prepared by Technical Committee CEN/TC 144 “Tractors and machinery for agriculture and forestry”, the secretariat of which is held by AFNOR. 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of an identical text or by endorsement, at the latest by June 2019, and conflicting national standards shall be withdrawn at the latest by June 2019. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. Cableless control systems are increasingly used in forestry. As only the fundamental requirements are defined in the standard EN 62745, it is necessary to formulate a draft standard that defines the particular requirements in respect to safety in forestry. This standard draft regulates all special features of cableless control systems up to the machine interface. Safety system specifications for the machines resulting through cableless control systems according to this standard or which are controlled according to these specifications can be found in the relevant safety standards of these machines (e.g. EN ISO 11850). 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 2006/42/EC amended by Directive 2009/127/EC and EU Directive 2014/30/EU. For relationship with EU Directives, see informative Annex ZA, which is an integral part of this document. According to the CEN-CENELEC Internal Regulations, the national standards organisations 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 17067:2018 (E) 5 Introduction This document is a type-C standard as stated in EN ISO 12100.

This document is of relevance, in particular, for the following stakeholder groups representing the market players with regard to machinery safety:

— machine manufacturers (small, medium and large enterprises);

— health and safety bodies (regulators, accident prevention organizations, market surveillance etc.)

Others can be affected by the level of machinery safety achieved with the means of the document by the above-mentioned stakeholder groups:

— machine users/employers (small, medium and large enterprises);

— machine users/employees (e.g. trade unions, organizations for people with special needs);

— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).

The above-mentioned stakeholder groups have been given the possibility to participate at the drafting process of this document.

The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are covered are indicated in the scope of this document.

When requirements of this type-C standard are different from those which are stated in type-A or type-B standards, the requirements of this type-C standard take precedence over the requirements of the other standards for machines that have been designed and built according to the requirements of this type-C standard. SIST EN 17067:2019

EN 17067:2018 (E) 6 1 Scope This document specifies both common and machine specific requirements for cableless control systems for use with the following forestry machinery.

— forestry cable winches according to ISO 19472, winches for log splitters; — self-propelled machinery for forestry according to EN ISO 11850 (machines for felling, moving and debranching, forwarders, log loaders, skidders, processors, harvesting machines, mulchers as well as multipurpose machines of these construction types, as described in ISO 6814); the definitive part of the standard defines essential requirements for the driving function of the machine; — mobile yarders for timber logging corresponding to EN 16517; — log splitters and combined firewood splitters according to EN 609-1:2016, 5.9.2.1 Chipping machines according to EN 13525 and chipping machines with mechanical feed systems for the production of woodchips and shredding /grinding machines; — forestry boom loaders and similar devices that are used on self-propelled machinery and trailers for forestry according to EN ISO 11850 and, as indicated above, for timber transport, timber loading, the loading of forestry goods or forestry products as well as for the handling and arrangement of timber harvesters, felling attachments, machines for felling and moving, attachments, saw heads, gripper-saw combinations with or without load or similar devices and machines, insofar they are not dealt with in EN 12999. Forestry boom loaders can be a component of the forestry machine on which they are mounted. This document deals with significant hazards (as listed in Annex ZA), hazardous situations and events relevant to cableless control systems used with the above specific forestry machinery when used as intended and under the conditions of misuse foreseeable by the manufacturer.

NOTE General requirements for cableless controls for machinery are given in the standard EN 62745 and these are applicable to cableless control systems of forestry machinery. This document deals only with the remote operation of machines. Risk reduction (protective) measures related to the operations carried out by the machine are specified in machine specific standards.

This document is not applicable to cableless control systems for forestry machinery manufactured before the date of its publication. SIST EN 17067:2019
