Overview

EN 13001-3-6:2018/FprA1 (CEN) addresses the limit states and proof of competence for hydraulic cylinders that form part of the load-carrying structures of cranes. It is intended to be used together with EN 13001-1, EN 13001-2 and EN 13001-3-1 and pertinent crane product standards. The standard focuses on design and theoretical verification to prevent mechanical hazards while excluding hydraulic piping, hoses, connectors and cylinders made from materials other than carbon steel.

This amendment clarifies normative references, material and weld requirements, and the verification methods used to demonstrate static strength, fatigue resistance and elastic stability for cylinders used in cranes.

Key Topics

• Scope and exclusions: Applies to hydraulic cylinders that are integral to crane load-carrying structures; excludes piping, hoses, connectors and non-carbon-steel cylinders.
• Limit state approach: Uses the limit state method (as per EN 13001-1) to assess structural resistance and safety.
• Proof of static strength: Verification by calculation to avoid excessive deformation, yielding or fracture. Dynamic factors from EN 13001-2 are used to produce equivalent static loads.
• Fatigue strength: Assessment to prevent crack initiation and propagation under cyclic loading using cumulative damage concepts and stress history parameters referenced to EN 13001-3-1.
• Elastic stability: Rules for preventing elastic instability (column buckling) of rods and other compressive members, including reference to second-order calculations when required.
• Materials and weld quality: Requirements reference EN ISO 5817 and EN ISO 148-1 for weld quality and impact toughness; weld quality lower than class C is not permitted for fatigue-sensitive details.
• Active vs passive cylinders: Distinction affects design pressure factors and safety evaluations when calculating design stresses.

Applications

• Design engineers and structural analysts verifying hydraulic cylinder integrity in mobile and fixed cranes.
• Manufacturers producing carbon-steel hydraulic cylinders intended for crane load-bearing service.
• Safety and conformity assessors using EN 13001-3-6 together with EN 13001-1/2/3-1 to demonstrate compliance with essential safety requirements and support conformity assessment under the Machinery Directive.

Practical benefits include reduced risk of yield, fracture, fatigue failure and buckling through harmonized verification methods and clear material and weld controls.

Related Standards

• EN 13001-1 - General principles and requirements (limit state framework)
• EN 13001-2 - Load actions and dynamic factors for crane components
• EN 13001-3-1 - Limit states and proof of competence for steel structures (material, fatigue and weld rules)
• EN ISO 5817 / EN ISO 148-1 - Weld quality and impact toughness test methods

For designers and regulators, EN 13001-3-6:2018/FprA1 is a practical reference to ensure hydraulic cylinders in crane load-carrying systems meet harmonized safety and verification criteria.

5 Modifications to Clause 5, Proof of static strength
st nd
In 5.1, replace the 1 and the 2 paragraph with the following:
“A proof of static strength by calculation is intended to prevent excessive deformations due to yielding
of the material, elastic instability and fracture of structural members or connections. Dynamic factors
given in EN 13001-2:2014 or relevant product standards are used to produce equivalent static loads to
simulate dynamic effects. Also, load increasing effects due to deformation shall be considered. The use
of the theory of plasticity for calculation of ultimate load bearing capacity is not considered acceptable
within the terms of this standard. The proof shall be carried out for structural members and
connections while taking into account the most unfavourable load effects from the load combinations A,
B or C in accordance with EN 13001-2:2014 or relevant product standards.
Cylinder actions are either active or passive. Active cylinders are moving in a direction opposite to the
direction of the external force acting on the moving part of the cylinder. Passive cylinders are either not
moving or moving in the same direction as the external force acting on the moving part of the cylinder.
As the forces applied to the cylinder by the crane structure are computed in accordance with
EN 13001-2:2014, they are already increased by the partial safety factors γ and relevant dynamic
p
