ABSTRACT OF THE DISCLOSURE A safety release bitt is pivotally mounted on a fixedly positioned bitt base for pivotal movement about a horizontal axis between a vertical position and a horizontal position; a cross pin is mounted on a pivot pin in the upper portion of said bitt for movement between an extended position in which the cross pin ex- tends outwardly of the bitt and a retracted position in which the cross pin is positioned inwardly of the bitt member with a linkage inside the bitt-connected to the bitt base serving to auto- matically move the cross pin from its extended position to its retracted position in response to movement of said bitt from its first position to its second position. A slidable lock bar on the bitt base locks the bitt in its vertical position with a hydraulic cylinder means optionally providing for actuation of the lock bar and other optional hydraulic cylinder means connected between the bitt and base to pivot the bitt between its horizontal and verti- cal positions.
