> Hello Jack,
>
> I had a steel fabricator install side by side, end to end, barn door slide
> rails on my 48 foot tower (the parallel rails are separated by about 10"),
> on which he attached a self designed and on the job fabricated elevator
> approximately 4 feet high, at the bottom of which the rotor is fastened
and
> the top of which the thrust bearing is installed. At the top of the tower
he
> designed a spring loaded grip (which can be decoupled by pulling a dacron
> rope) which holds the raised elevator firmly in place when fully raised,
> without relying on the cable. At the bottom he fashioned a platform inside
> the tower on which he attached a marine, hand operated, winch, which moves
> the elevator up and down through a heavy duty pulley fastened at the tower
> top. The cable coming off the winch slides on nylon strips on the outside
of
> the tower where ever it might touch. Unfortunately, I don't have any
> drawings, since he designed it, piece by piece, by the seat of his pants,
so
> to speak, as he went along. Works great and has been up for several years
> now. Makes antenna maintenance a snap at ground (chest)level.
