The reason you are getting the squeal when lowering the tower is because
of the slipping action on the clutch pads. The "brake winch" loosens
the clutch assemble in the down/unspool direction and the tension of the
cable is trying to tighten the assembly back up. You keep "unscrewing"
the clutch pack and the rotation of the drum tightens it back up. There
is constant slippage when rotating the handle. The pads can overheat if
you don't stop once in a while.
In the up direction, you are keeping constant pressure on the clutch
pack and there is NO SLIPPAGE. If you get squealing in the UP
direction, RUN AWAY! This means the clutch pack is slipping and the
tower can come down.
Contact Fulton for replacement clutch packs...

Subject: [TowerTalk] Problem with a Fulton 2550
From: "Kirk.Harding" <Kirk.harding@cox.net>

To: <TowerTalk@contesting.com>
I have a US Tower TX-472MDPL with the TRX-80HD Raising (and lowering)
fixture. Last week I lowered (laid the tower over) and noticed that I
have
to put a great deal of effort into cranking the Fulton 2550 winch. As a
matter of fact there was considerable squeaking coming out of the brake.
This problem is only when laying the tower over. When raising, the winch
works great. My question is, is there a facility where I can purchase
parts
for the Fulton winch? I've searched Google and find places where I
purchase
a new winch but (obviously), I'd rather not have to replace the
whole2550.
If I it ends up that I do have to replace the 2550 do you have any
replacement suggestions?
Many thanks,
Kirk, K6KAR
