This European Standard specifies general principles and requirements to be used together with EN 13001‑2 and the EN 13001‑3 series of standards, and as such they specify conditions and requirements on design to prevent mechanical hazards of cranes, and a method of verification of those requirements.

NOTE

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

The following is a list of significant hazardous situations and hazardous events that could result in risks to persons during normal use and foreseeable misuse. Clause 4 of this European Standard is necessary to reduce or eliminate the risks associated with the following hazards:

  1. instability of the crane or its parts (tilting);

  2. exceeding the limits of strength (yield, ultimate, fatigue);

  3. elastic instability of the crane or its parts (buckling, bulging);

  4. exceeding temperature limits of material or components;

  5. exceeding the deformation limits.

This European Standard is applicable to cranes which are manufactured after the date of approval by CEN of this standard and serves as reference base for the European Standards for particular crane types.
