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?
