CEN/TC 147

Project No.LVS EN 13001-3-6:2018
TitleCalculation methods and limit states for theoretical verification of the mechanical strength of hydraulic cylinders used in cranes. Outline of standard The standard will have a layout that is quite similar to EN 13001-3-1. It shall specify the calculation methods and provide limit states that are necessary to reduce or eliminate risks associated with the following hazards: 1. exceeding the limits of strength (yield, ultimate, fatigue); 2. elastic instability of the crane or its parts (buckling). In particular, the following phenomena will be addressed: • Hoop stress • Shell bending stress at bottom weld • Cylinder head flange weld • Notch stress at oil connectors • Stress at cylinder head thread • Stress at piston thread • Piston weld • Locking thread • Bolted cylinder head screws • Buckling of entire cylinder • Internal buckling of rod • Compressed member with end moments or lateral displacement (2nd order theory) • Mechanical interfaces
