ABSTRACT:

An automatic latching mechanism is provided which is operative in responsive to overtravel retracting movement of the trolley. The overtravel retracting movement of the trolley is taken up by slack adjustment mechanism to enable the gate to remain in its closed position during latching and unlatching of the gate.
