<p>The positioning drive (12a) has a stationary drive motor driving a pinion that engages chain elements of a chain segment associated with a part to be positioned, whereby at least those elements supported on the surface of the part to be positioned in which the pinion is engaged, whereby the surface for supporting the chain elements is convexly curved. The teeth of the pinion are dimensioned so that there is rack-and-pinion gearing between the pinion and the chain segment. An independent claim is also included for a solar module positioning device.</p> |
