Abstract:
A system for coupling excavation equipment components, comprising:an elongate, retainer pin body defining a cylindrical bore extending at least partially through the retainer pin body; an elongate, generally cylindrical valve configured to be received at least partially within the cylindrical bore; at least one detent extending at least partially through a slot in the retainer pin body, the slot being generally perpendicular to the cylindrical bore and extending from the cylindrical bore to an outer surface of the retainer pin body; the valve having a first position in which the valve contacts the at least one detent and the at least one detent extends beyond the outer surface of the retainer pin body, and a second position in which the at least one detent is retracted with respect to the first position; and a biasing element disposed within the cylindrical bore, the biasing element exerting a force on the first end of the valve.
