A tilt hoist system for breaking down a lumber stack having tiers of lumber. The tilt hoist system includes a tilt hoist apparatus to successively bring a topmost tier thereof at a release location, an outfeed, a transition assembly for guiding each tier of lumber to the outfeed, and a transition assembly controller. The transition assembly includes an inclined transition track having a top end positioned to receive each tier of lumber from the tilt hoist apparatus, and a bottom end adjacent to the outfeed. The transition assembly also includes movable retaining arms configurable in a top end configuration in which the retaining arms are positioned to hold said topmost tier at the release location and a bottom end configuration in which the retaining arms are positioned past the bottom end of the transition track. A retaining arm actuator is operatively connected to move the retaining arms.

A rotary apparatus or machine that takes or receives a barrel stack of mounted tires in the vertical position (i.e., barrel stacked), and rotates the stack as a whole to a horizontal position, where each unit or tire is an upright position. The tires can then be rolled off individually or in multiple units to be installed on the equipment being built, or transported from the tire holding area to the assembly floor or installation area.
