[TowerTalk] Anyone Using a Fulton KW3000 Winch with Powerful 1/2 inch Pistol Drill for tower tilting ?

[Al Williams]

I have a question on overheating winch brakes.

I replaced the K1550 on my LM470 tiltover fixture with the K2550 and that 
eliminated the very loud squealing when tilting the tower down.  I also 
added two more pulleys to the arrangement for a total of four as does the US 
tower HDX572.  It takes a lot more cranking with four pulleys but it is also 
much easier.  I assume that the load on the winch
is less--but is it?  I use a drill to turn the winch when tilting.

I have been intermittently stopping when lowering the tower to let the brake 
cool off but I wonder if that is necessary.  Is the load on the brake winch 
less now that I have four pulleys instead of two in the cabling system so 
that it won't heat up as much?
