ABSTRACT:
A hatch cover closure system for use on hopper cars. A flexible resilient strap is used to secure a hatch cover, the strap and hatch cover being coupled together by a floating link and raised and lowered as a unit about a hatch cover hinge. A slidably mounted U-bolt is used to exert a force on an end of the strap which, in turn, forces the cover to the housing.
