Patrick, AF5CK's thread on his tower raised an issue that I really don't understand... Why isn't there a "lock" mechanism on crank up towers? We spend lots of money on these things, and, basically, t

There was a discussion on this topic a couple weeks ago, check the archives. I think it comes down to the bean-counters. Of course something *could* be done. If hams want to pay for it is another dis

Okay, after some searching I found the thread entitled "How to apply lube to HDX589 " and references to a Versatower lock. No wonder I missed it! I'm prepared to go to some effort to build or adapt a

My AlumaTower crank up has a positive pull down, and has a lock mechanism whereby the tower can be locked at any cross member point at any height. This is a spring powered piece that flips down and l

I have been around a long time and had a few crank up towers, I have never had one come down or known anyone to have one collapse. There is a huge safety factor built in with the cables. If it is loo

I had one collapse vertically during a storm while I was at the base and it is scary. I just sensed it was collapsing and took off across the backyard covering the distance in not too many steps and

This is why I like motorized towers like LM-470 with a positive pull down system. I experienced your problem first hand and managed to catch it in time, that sudden jerk on the cable probably exceede

Is there any reason that in a 3 section tower that the two upper sections do not have independent cables and winches?? That way if one fails, they both don't come down. Gary J N5BAA _________________

I suspect that if an upper section support were to fail, supports for other seconds below might be stressed to failure by falling sections. I remember vividly watching this effect on TV on a couple o
