[TowerTalk] Freeway lighting monopoles

[RICHARD BOYD]

Some of the large cellular monopoles, I believe, have an access panel at ground level and an internal ladder to the top.  This would mean the diameter would have to stay relatively large even at the top.

Otherwise, it would be relatively simple to install external "pegs" (steps) like the Telrex Big Bertha has, or like wide self supporters often have on one leg -- like cross country HV line towers have too.  73 - Rich, KE3Q

  Next time you drive past one notice the access panel at chest height near
  the ground.  I think there's a winch in there where the crew lowers the
  light head to ground level to perform maintenance.

  I would not know this except I saw a crew changing bulbs once - the lighting
  equipment head which usually lives at the top was down about 5 feet off the
  ground.  Ingenious.  Sort of like an "internal Hazer."  It must also have a
  lot of extra AC cable in there because what comes down must go up, or
  whatever.  Maybe they disconnect the electricity before they lower it, and
  the wire end goes up, then when the head goes back up the wire comes back
  down.  Then they plug it in again and test their work.

  KJ6Y may have to explain this one to me.  Eh, Skip?

  Mark, N5OT
