36、 as well as pertinent crane type product EN standards, and as such they specify general conditions, requirements and methods to, by design and theoretical verification, prevent mechanical hazards of hydraulic cylinders that are part of the load carrying structures of cranes. Hydraulic piping, hoses

37、and connectors used with the cylinders, as well as cylinders made from other material than carbon steel, are not within the scope of this standard.The following are significant hazardous situations and hazardous events that could result in risks to persons during intended use and reasonably foreseea

38、ble misuse. Clauses 4 to 7 of this standard are necessary to reduce or eliminate risks associated with the following hazards:a) exceeding the limits of strength (yield, ultimate, fatigue);b) elastic instability (column buckling).NOTE EN 13001-3-6 deals only with the limit state method in accordance
