ABSTRACT:
A swivel housing (22) at the lower end of a davit (10) is introduced into an open side of a socket (20). The socket (20) is mobile and it includes hook members (136, 140) at its lower end which fit through openings (60, 62) in a base member (18) which is incorporated into a rooftop (12). The socket (20) is then slid sideways to place the hook members (136, 140) below hook engaging portions (90, 94 or 92, 96) of a top wall (56) of the base member (18). Then, a filler member (146) is inserted into a portion of the opening (60, 62) which is vacated by the sideways shifting of the socket (20), to block unwanted sideways shifting of the socket (20) in opposite direction. The swivel housing (22) at the lower end of the davit (10) is inserted into the open side of the socket (20) while the davit is in a horizontal position. Then, a pivot pin (188) is inserted and the davit (10) is swung upwardly about the pivot pin (188). Then, a lock pin (196) is inserted to lock the davit (10) in an upright position.
