Hatch arrangement for covered hopper cars

摘要

A hatch cover assembly (1) for a railway car (C). A hatch cover (7) is hingedly mounted to a roof (R) of the car for pivotal movement of the cover to open and close a hatch. The axis about which hinging movement occurs is perpendicular to the center line (CL) of the car. A locking strap (31) is rotationally mounted to the cover for movement between a cover locking position and a cover unlocking position. The longitudinal axis of the strap when the cover is in its locking position is also perpendicular to the center line of the car. A latch mechanism (61) adjacent the cover latches the strap in its cover locking position to prevent movement of the strap.
