Influence lines for runway cranes

[juliangrus]

Hello, I am trying to model an industrial building with several runway cranes and I would like to know if there is a way of dealing with the crane girders as bridge beams, with the influence lines method. I would prefer not to use the bridge design module, as the vehicle define option has no option for lateral load, i.e. load moving or stopping perpendicular to any runway crane girder. Thanks in advance.
