Abstract: An apparatus includes a latch and a travelling nut. The latch couples to a deck of an auto rack car. The latch includes a body coupled to a hinge such that the body may rotate about the hinge from a first position to a second position. The body includes a key. The travelling nut engages a ball screw. The travelling nut includes a slot. The travelling nut rotates with the ball screw when the body is in the first position. The key engages the slot when the body is in the second position. The travelling nut and the latch adjust a height of the deck in the auto rack car when the body is in the second position and when the ball screw is turned.

Abstract: A moveable boom hinge apparatus is provided. The moveable boom hinge apparatus provides a mechanism offsetting the tip portion of a boom hinge from the base portion of a boom hinge when the tip and base portions are folded parallel to each other and securely position the tip portion of the boom when extended. Additionally, this moveable boom hinge apparatus provides a uniquely u-shaped link element and complementary u-shaped catch element that couple together in a way that sufficiently locks the tip portion into place with respect to the base portion and keeps structural loads of a boom hinge aligned with structural members of a boom hinge during its boom hinge's transition from the operational position to the non-operational position. This alignment significantly reduces bending moments that weaken structural materials over time.
