A tilting apparatus for emptying materials, including bulk material, out of railcars that are open at a top may include a tilting frame that is rotatable about an axis of rotation D and is connected to a platform that can receive at least one railcar, a clamping arm attached to the tilting frame in a rotatable manner, a locking device for preventing relative movement of the tilting frame and the clamping arm, and a bracket that is attached to the clamping arm such that in a tilted position of the tilting apparatus in which the tilting frame has been rotated about the axis of rotation that bracket lies at least partially against an upper edge of at least one of the side walls of the at least one railcar. Further, the hydraulic cylinder may be attached to the bracket.”

A railcar dumper system utilizes a trunnion wheel assembly to support a rotary rail car dumper having a rotary frame assembly supported by at least four trunnion wheel assemblies positioned along the ends of the rotary frame assembly. Each trunnion wheel assembly includes an equalizer bracket and a pair of trunnion wheel units selectively connected and disconnected from opposite ends of the equalizer bracket. Each trunnion wheel unit has a respective trunnion wheel bracket supporting a respective trunnion wheel that rotates within the trunnion wheel bracket. An equalizer support pivotally connects to the equalizer bracket between the opposite ends.

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.
