Abstract: A center column drive for a spiral conveyor is used to rotate a drive tower to move a conveyor belt in a helical pattern. The drive tower is driven by the center column drive to cause rotation about a vertical axis. The center column drive includes a base having a platform and a plurality of support legs that support the platform. The center column drive also includes a slew ring that is secured to the platform at one end and to a center column of the drive tower and a second end. Rotation of an electric gear motor causes rotation of a portion of the slew ring, which, in turn, rotates the drive tower.
