摘要： A bar lock assembly including a lock rod having first and second lock rod portions and defines a rotational axis. A second lock rod portion section telescopically extends from the first lock rod portion when the bar lock assembly is in a first condition. The second lock rod portion is substantially retracted within the first lock rod portion when the bar lock assembly is in a second condition. An elongated handle having opposed ends extends from the first lock rod portion. One handle end is pivotally connected to the first lock rod about a fixed axis. Linkage between the handle and the second lock rod portion telescopically moves the second lock rod portion. This lock bar assembly is configured such that an angle of about 45° is established between the handle and a generally horizontal plane when in the first position to enhance ergonomic operation of the bar lock assembly.

摘要： A mechanism for operating a discharge gate assembly mounted on a railcar. The gate assembly includes a frame defining a discharge opening, a door slidably positioned on the frame for a generally horizontal range of movements between a closed position and an open position. An operating shaft assembly is mounted on the frame for rotation about a fixed axis and is operably coupled to the door such that the door moves in response to rotation of the operating shaft assembly. The mechanism for operating the discharge gate assembly includes a mount carried by and with the railcar and an actuator carried by the mount outside a range of travel of the slidable door. A force transfer mechanism is operated by the actuator for rotating the operating shaft assembly to slidably move the door between the closed and open positions in response to operation of the actuator.
