To allow simultaneous operation of two or more shafts, to allow the shafts to follow a curved line having a constant/variable radius, and to minimize a demand for a rotation space.

A transporting means operation assembly 1 is firmly connected to a transporting means and constructed of at least one track 2 supported by a supporting structure 3 having a central bearing 5 in an upper area for connection allowing rotation of at least one axle 12 around the vertical axis. In at least one axle 12, wheels 14 placed on the ground or a separate support are arranged in both ends, and each of these wheels 14 is provided with an electric or hydraulic motor 15 and the like controlled by an electric/electronic control means for rotating the axle 12.
