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, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom

Introduction

This European Standard has been prepared to be a harmonised standard to provide one means for crane controls and control stations to conform to the relevant essential health and safety requirements of the Machinery Directive 98/37/EC

This European Standard is a type C standard as stated in EN 1070

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

When provisions of this type C standard are different from those which are stated in type B standard, 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 health and safety design requirements for controls and control stations for all types

of crane

NOTE 1 Control systems are covered by other standards e.g EN 60204-32, EN 13135-1 and prEN 13135-2

Annex C provides additional value to the requirements for cableless control systems as specified in EN 60204-32

NOTE 2 Annex C will be deleted after WG 3 agreed to introduce it into their document EN 13135-1

NOTE 3 Specific requirements for particular types of crane are given in the appropriate European Standard for the particular crane type

This standard does not deal with noise hazards because these are dealt with in safety standards for specific types

of cranes It also does not address the design of the cabin with regard to its sound insulation properties

This European Standard covers specific hazards which could occur during the use of controls and control stations It does not cover hazards which could occur during transport, construction, commissioning, modification, maintenance, de-commissioning or disposal

The hazards covered by this standard are identified in clause 4

This European Standard is applicable after the date of approval by CEN of this standard

This European Standard incorporates by dated or undated reference, provisions from other publications These normative references are cited at the appropriate places in the text and the publications are listed hereafter For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision For undated references the latest edition of the publication referred to applies (including amendments)
