The wheels were constructed like chariot wheels; their crossbars, rims, spokes, and hubs were made of cast metal.

Each stand had four bronze wheels with bronze axles and four supports. Under the basin the supports were fashioned on each side with wreaths. ¹ 

The four wheels were under the frames and the crossbars of the axles were connected to the stand. Each wheel was two and one-quarter feet ¹  high.
