EN 13001-3-1 specifies limit states, requirements and methods to prevent mechanical hazards in steel structures of cranes by design and theoretical proof of competence. The significant hazardous situations and hazardous events that could result in risks to persons during intended use are identified in an informative Annex L (informative). EN 13001-3-1 does not apply to cranes that are designed before the date of its publication as EN.
Clauses 4 to 8 of EN 13001-3-1 provide requirements and methods to reduce or eliminate these risks:
— exceeding the limits of strength (yield, ultimate, fatigue),
— exceeding temperature limits of material or components,
— elastic instability of the crane or its parts (buckling, bulging).
This standard is one part of the EN 13001 series of standards. The other parts are:
— Part 1: General principles and requirements,
— Part 2: Load actions,
— Part 3-2: Limit states and proof of competence of wire ropes in reeving systems,
— Part 3-3: Limit states and proof of competence of wheel/rail contacts,
— Part 3-4: Limit states and proof of competence of machinery,
— Part 3-5: Limit states and proof of competence of forged hooks and cast hooks,
— Part 3-6: Limit states and proof of competence of hydraulic cylinders.
