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 locks the sections
together when activated (or released).

Subject: [TowerTalk] Crankup tower safety question... (Crankup Danger!)
Patrick, AF5CK's thread on his tower raised an issue that I really don't
Why isn't there a "lock" mechanism on crank up towers?
We spend lots of money on these things, and, basically, they hang there
suspended by a single cable. We all have either known someone or have had
our own tower's cable (or winch) fail and the tower crashes, with great
damage to tower and antennas.
I could thing of a number of gadgets that could be made to work:
- A solenoid locking bolt
- A brake mechanism (Electronically controlled?)
- Stops every few feet requiring a raise then lower like a safety ladder.
But here I am, about to step off into yet another $10k tower project with
another tower hanging by a cable. (I feel like Homer Simpson - Doh!)
I realize that the market is small and price sensitive for these towers,
but certainly this has been recognized as a problem.
Isn't there a better way? If there is, and I can implement it, I'd do so,
simply for the purpose of making the tower safer for me and my antennas.
