This European Standard applies to:
-
light crane systems, either suspended or free-standing systems;
-
pillar jib cranes;
-
wall-mounted jib crane.
For illustration of crane types, see Annex B.
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.
