In 5.2.2.3, replace the whole subclause with the following:
"Trolley wheels generally transmit vertical and horizontal wheel loads. The effects of these wheel loads on the
supporting structure shall be taken into account in combination with global stresses.
Distribution of wheel loads of a crane or a trolley shall not be considered equalised unless equalising is
ensured by appropriate arrangements (e.g. pinned bogies, balancers, flexibility of structures).
Stresses in the web under the rail, resulting from vertical wheel loads, shall be calculated in conformance with
EN 13001-3-1. When passing over girder cuts (e.g. from main girder to cantilever), the effective distribution
length is halved, which shall be taken into account in the calculation.
NOTE Annex F presents one permissible method to determine the stresses in the case of cranes with the trolley
travelling on the lower flange of the girder.
The local stress due to the wheel load shall be combined with the global normal and shear stresses for the
determination of the equivalent stress in accordance with the principles given in EN 13001-3-1.
For fatigue assessment in accordance with EN 13001-3-1
• the total number of wheel overruns at the mostly loaded position shall be taken into account;
