UNIT FOR ACTUATING GATES OF A HOPPER RAILROAD CAR

摘要

One double acting cylinder is attached to the doors of a gate assembly via a linkage. A lock out system cooperates with the linkage whereby different par ts of the linkage may be immobilized prior to the beginning of a work cycle. The work performed by the double acting cylinder thus passes through the free parts of the linkage to actuate one door ar the other.
