Abstract
An embodiment of a self-releasing cable lift system may include a latch coupled to a winch and operable to lift an object, such as a gangway, into a secured position before self-releasing after the object is locked into place. Such a latch may be biased to an open position when setting free, but biased to a closed position when acted upon by an outside surface. Thus, the latch includes a first biasing surface that is operable to bias the latch to the closed position when the latch is moved into contact with a latch receptacle in a first direction. Further, the latch includes a second biasing surface that is operable to bias the latch to a closed position when it is moved into contact with a sleeve, in a second direction. In this manner, the latch may engage a gangway, when lowered, but then self-release when the gangway has been raised.
