The spiral chute also includes a plurality of chute assembly sections, each including a chute support arm, a chute section coupled to the chute support arm, an outer wall support coupled to a distal end of the chute support arms, an outer wall segment coupled to the outer wall supports, and a support arm bolt having a distal end and a proximal end. The distal end of each support arm bolt passes through a corresponding one of the first plurality of opposing apertures and engages a proximal end of the chute support arm such that the proximal end of the chute support arm abuts the first center column segment.
