a first support arm with an idler end, said first support arm coupled relative to said cable drum, and said first support arm adjustable to adjust a distance between said cable drum and said idler end, and said first idler end receiving said first supply of cable; and
a second support arm, with a second idler end coupled to said second support arm, said second idler end receiving said second supply of cable, wherein said first support arm includes a first support part having a first inner size, and a second support part having a second outer size that fits within and slides within said first support part.
2. A winch device as in claim 1 , wherein said second support arm adjustable to adjust a distance between said cable drum and said second idler end.
3. A winch device as in claim 1 , wherein said first and second support arms are held one relative to another in a first mode, and allowed to move in a second mode.
4. A winch as in claim 1 , wherein said drum has two slots therein, each holding a separate supply of cable, and where said two slots rotate in sync with one another to wind and unwind said cable in sync.
5. A winch as in claim 4 , wherein said slots each hold only a single stack of cable.
6. A winch as in claim 5 , wherein said drum is no thicker than either one of said first and second support arms.
7. A winch as in claim 5 , wherein said drum is no more than 1.5 times thicker than either one of said first and second support arms.
8. A winch device comprising:
a cable drum that releases and wraps first and second different supplies of cable simultaneously, said cable drum having a first maximum thickness;
a first support arm with an idler end, said first support arm coupled relative to said cable drum and receiving said first supply of cable from said cable drum; and
a second support arm, with a second idler end coupled to said second support arm, said second idler end receiving said second supply of cable from said cable drum, said cable drum having a second maximum thickness, and wherein said first maximum thickness is no greater than said second maximum thickness, said second support arm adjustable to adjust a distance between said cable drum and said second idler end, wherein said first support arm includes a first support part having a first inner size, and a second support part having a second outer size that fits within and slides within said first support part.
9. A device as in claim 8 , wherein said first support arm adjustable to adjust a distance between said cable drum and said first idler end.
10. A winch device as in claim 8 , wherein said second support arm adjustable to adjust a distance between said cable drum and said second idler end.
11. A winch device as in claim 8 , wherein said first and second support arms are held one relative to another in a first mode, and allowed to move relative to one another in a second mode.
12. A winch as in claim 8 , wherein said drum has two slots therein, each holding a separate supply of cable, and where said two slots rotate in sync with one another to wind and unwind said cable in sync.
