Introduction
This European Standard is a harmonized standard to provide one means for loader cranes to conform to the essential health and safety requirements of the Machinery Directive 2006/42/EC. This EuropeanStandard is atype C standard as stated in EN Iso12100. 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. The machinery concerned and the extent to which hazards are covered are indicated in the scope of this European Standard.

1 Scope This European Standard specifies minimum requirements for design, calculation, examinations and tests of hydraulic powered loader cranes and their mountings on vehicles or static foundations. This European Standard does not apply to loader cranes used on board ships or floating structures or to articulated boom system cranes which are designed as total integral parts of special equipment such as forwarders. The hazards covered by this standard are identified in Clause 4. This European Standard does not cover hazards related to the lifting of persons. This European Standard is not applicable to loader cranes which are manufactured before the date of its publication as EN. NOTE The use of cranes for lifting of persons can be subject to specific national regulations
