The present disclosure provides embodiments of tilt hoists and lumber unstacking systems with a rotation table, a tier alignment system, or both. The rotation table may include a base and a tilt frame supported on the base. The tier alignment system may include an alignment beam and an actuator operable to raise and lower one end of the alignment beam relative to the opposite end to thereby adjust the lateral slope of the spill edge. Optionally, a control system may include distance sensors to detect tiers of lumber as they approach the spill edge and a computer system configured to determine a difference between the lateral slope of the tier and the lateral slope of the spill edge. The computer system may also be configured to automatically adjust the slope of the spill edge to match the slope of the tier before the tier is spilled over the spill edge.
