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.

Tilt hoists and lumber unstacking systems

Embodiments provide an electric lug loader system. An electric lug loader may include a shaft assembly rotatably mounted to a frame that extends across a flow path. The shaft assembly may have shafts arranged radially around, and parallel to, the rotational axis of the shaft assembly, clamp members arranged along each of the shafts, support members arranged radially around the rotational axis and across the flow path, and electric drives coupled to the shafts. Conveyors may be coupled with the frame and spaced apart across the flow path upstream and/or downstream of the shaft assembly. Additional drives may be coupled with the shaft assembly and the conveyors. A controller may be configured to synchronize the drives to engage successive workpieces between the clamp members and the support members and deposit the workpieces onto a lugged conveyor. Other embodiments provide related methods and systems.

Embodiments of the present disclosure generally provide a variable phase step feeder including a fixed set of stairs and a moving set of stairs. The fixed set of stairs may include a first fixed step, a second fixed step, and a third fixed step. The moving set of stairs may be interposed between the fixed set of stairs, and include a first moving step adapted to transport a workpiece from the first fixed step to the second fixed step and a second moving step adapted to transport the workpiece from the second fixed step to the third fixed step. The variable phase step feeder may further include a control mechanism for adjusting a phase relationship of the first moving step relative to the second moving step.
