    Need to calculate motor size to drive skip dolley system. have the following:
    Frame on 6 wheels. Gearbox/motor driving middle pair of wheels.
    Total mass 12t
    Need to move trolley @ 5m/min

    Any thoughts where to begin?

    Well I'll take a stab at it,

    whats the ratio on your gearbox?

    size of wheels?

    is the trolley for use on a flat surface or how steep are the biggest inclines?

    What sort of load will it be carrying? is 12t the maximum load or just the weight empty?

    Once you know those, I think we can figure out the maximum torque needed from your motor.

    Wheels = 230mm
    flat surface
    max load = 12t
    ratio on gearbox=? Don't know the ration since we need to source it still...
