Cranes. General design – Limit states and proof of competence of wire ropes in reeving systems
| Published By | Publication Date | Number of Pages |
| BSI | 2014 | 40 |
This European Standard is to be used together with EN 13001‑1 and EN 13001‑2 and as such they specify general conditions, requirements and methods to prevent mechanical hazards of wire ropes of cranes by design and theoretical verification.
Specific requirements for particular types of cranes 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 intended use and reasonably foreseeable misuse. Clauses 5 to 6 of this standard are necessary to reduce or eliminate risks associated with the following hazard:
-
exceeding the limits of strength (yield, ultimate, fatigue).
This European Standard is not applicable to cranes which are manufactured before the date of its publication as EN and serves as reference base for the European Standards for particular crane types (see Annex C).
EN 13001‑3‑2 deals only with the limit state method in accordance with EN 13001‑1 .
