ABSTRACT:
A rotary locking mechanism connects an upper ramp and a lower ramp of a split ramp railway car. A pin carrier supports a coupling pin and is mounted to the lower ramp by a swivel pin. The pin carrier can pivot horizontally relative to the lower ramp. A dual vertical rotor lock is mounted to the upper ramp. The rotor lock includes first and second coupling disks which have rotor slots or grooves for receiving the coupling pin. The coupling disks have a horizontal axis of rotation so that the disks are vertically mounted. The action of the coupling pin entering the grooves in the first and second coupling disks will automatically rotate the coupling disks into a locked position. Locking pins then engage slots in the peripheries of the coupling disks to secure the coupling disk in the locked position.
