         or  14, guides  13 and  15 are positioned about the pulleys,
         respectively. From winch drum 16, cable 26 extends across
         the axial length of bumper 2 to pulley 12, further extend-
         ing to pulley 14, and then to swivel-sheave 25 from which
         cable 26 with hook 24 attached hangs free for use. In the
         embodiment illustrated, the winch system is powered by hy-
         draulics, but could just as well be powered using mechani-
         cal, electric, pneumatic, or internal combustion drives. The
         type of power chosen does not change the principles of the
         invention and all such power sources, including solar and
         others not so identified, but suitable, are contemplated for
         use with the invention.
