I replaced the k1550 winch with a k2550 winch but it was still pretty
difficult to crank so I modified the raising (layover) pulley arrangement by
adding two more pulleys to get the mechanical advantage. Now it is much
easier to crank but takes a lot of crank turns which means that I am lifing
my arm weight much more. I have been using a 1/2 drill that works fine
(after I manually get the tower lifted up a bit) and of course it is easier
to lower the tower. I have never seen smoke from the brake pads or heard
any squeal protest.
I am curious as to whether the pressure on the brakepads ( hence less squeal
and smoke) is decreased if the weight that the winch is lifting is reduced.
Perhaps a mechanical engineer can answer this (or other qualified person!)?
