I think he’s more on about the power required for hiab hydraulics?I think you are talking about my Idea
Essentially there's no need of hydraulic
The gantry crane is on wheels ,this ones are into the rails this to keep the gravity center as low as possible preventing to roll out
Generally all this kind of crane I've seen are moved by hand but is possible use a gate track and motor to the crane a long the rails
But I haven't notice if we know how much load should elevate this crane but I think that the OP will never need to lift more than 1 ton
If he needs more than that he should firstly make researches about materials and design
