About 3 years ago when I was looking for a bigger replacement for the Fulton
k1550 winch to be used with the LM470 motorized crankup, I called Fulton for
their advice. I was thinking about one their worm gear drive winches but
the sales rep (?) at Fulton recommended against worm gear drive winches and
instead recommended the k2550 which I purchased.
As I recall this sales rep said the worm gear drive winch wouldn't hold (my
words). Unfortunately I didn't pursue this and have often wondered if the
sales rep was correct. Especially after a recent incident with the k2550
being in a "free spool" mode when I began lowering the tower. I noticed
that the winch handle was turning by itself because of the load (yet nearly
vertical). Fortunately it was turning slowly so I grabbed the handle to
stop it.
It appears that the k2550 brake mechanism has something in it that requires
"setting" to be sure that the brake is activated. I would
sure appreciate if Jim Lux or another expert will describe how brake winches
work.
