An apparatus is disclosed for tensioning lines of a winch (16, 116) having a reel (19, 119) and three lines (32, 34, 36) wound about the reel (19, 119). The apparatus is used to position an object (12) on a support (14). The first and second lines (32, 34) are wound about the reel (19, 119) in a first direction and the third line (36) is wound about the reel (19, 119) in a second direction opposite the first direction. The first line (32) extends around the first guide (46), the second line (34) extends around the second guide (48), and the third line (36) extends between the first (46) and second (48) guides. All three lines (32, 34, 36) are connected to each other (32, 34, 36) and to the object (12) at their distal ends (38, 40, 42). An inner frame (70, 170) and an outer frame (72, 172) each contact the first and second lines (32, 34). At least one of the inner frame (70, 170) and outer frame (72, 172) moves with respect to the other of the inner (70, 170) and outer frame (72, 172) to maintain tension in the first (32) and second (34) lines. |
