    Why is it necessary for this mechanism to be so incredibly heavy duty? It doesn’t look like those rollers would have enough purchase on whatever they were feeding to need such heavy duty drive components.

    That is obviously just the bottom half of the feed table...

    To answer your question this is a new install evident by the tape still on the rollers the sheet of material shown being transported is a test and adjusting slab.
    the rollers must be synchronisticly adjusted for contact and alignment. It is being run at a very slow speed for observation and videoing purposes. After they are satisfied with the alignment of the bottom half a mating cassette will be added above this, however the top cassette will have an infinite amount of adjustments to turn a hot billet into the thickness of plate desired. The red hot sheets will be rolled through this machine at near ballistic speeds 100's to 1000's of meters per minute so yes the mechanism needs to be very robust
    Never try to tell me it can't be done

    That's a mesmerizing meshing – of some particularly unique gears.

    So, when the installation is completed, the gears will be covered and operating with constant lubrication, and protected from dust and grit in the mill...

    Just thought of this, if it is a rolling mill, with the material getting thinner as it passes each set of rollers, each set of rollers has to be running faster that the previous set. Wondering how that would accomplished with what appears to be that each roller is directly linked to the others, so they all run the same speed.

    Maybe this is the conveying system after or between a series of rolling mills. You are correct the shaft driving the rollers is 1 continuous shaft without and means of individual acceleration. if it were between rolling mills then I would think it would have been only the 1 cassette of rollers instead of 2. The first one already has the cover installed,
