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. The amended provisions concerning stress calculations are not compulsory for cranes designed before the date of availability of EN 12999:2011+A2:2017 .
NOTE
The use of cranes for lifting of persons can be subject to specific national regulations.
