[TowerTalk] Lifting Mechanism for a Tower

[Jon Pearl - Laptop]

Hi Tony.

I use one of these that's attached to a welded aluminum plate/shelf that is 
bolted to the side of my tower where the Fulton style winch was originally 
mounted.  It's essentially an engine hoist that's mounted in an inverted 
fashion to lift sections #2 and #3 (355 lbs. for the pair) of my US Tower 
TX-455.  It works well for the few times a year that I actually drop the 
tower and it's relatively quick.  All of the boat hoists below are driven by 
reduction pulleys and worm gear and are a bit slower but I'm sure they'll 
outlast the hoist that I'm using.

Long, about the middle of this page you'll find "The difference between a 
winch and a hoist."
