Motive power

Motive power is provided by a series of automotive window winder motors which I obtained at a very reasonable price as a factory surplus.

At each end of the conveyor belts there is a 6 inch wide aluminium roller driven by a window winder motor, with adaptive gears made for the purpose:

The bucket wheel frame also incorporates two driver's cab assemblies which can be raised and lowered in two 'lift shaft' appendages at the sides.  These cab assemblies are only 2kgs each and can be driven up and down by Meccano's little 6 volt plastic utility motors, driving small winches.
