ABSTRACT:
A resettable lockout means for an overload indicating winch lever is disclosed that automatically trips in response to overload applied to the lever forcing the lever members out of normal operating alignment and actuating an associated overload indicator. The winch operator desiring to remove the tell-tale overload indication and to restore the members of the operating lever into normal operating alignment is required to reset the lockout device through a deliberate procedure involving removal of a lockout device holder, followed by manual resetting of the lockout device within the winch lever.
