I do not know what I am talking about BUT
I DO have this 52' HyGain crank up still needing to have its cables
replaced, etc and so on. I do not plan to hand crank that sucker so
your thread is very welcome. obviously, mine is not a lightweight
like yours as it is a three piece steel. about a ton I guess.
anyway, I know that once I have it fully extended, there should be a
mechanical device to lock it so that it cannot come back down.
clutches are really for letting a load down s-l-o-w-l-y or at least as
slowly as you could do so with the handcrank. however, there are lots
of stories of broken hands, wrists, arms, etc from that crank getting
away and spinning like crazy as the tower collapsed upon itself.
point is, we need a clutch to get it up and a clutch to let it down in
a controlled manner. once we get it to where we want it to stop,
there should be a mechanical manner to stick a nail in a couple of
holes or somesuch<G> instead of counting on the clutch to hold it with
the power off. also, we do not want to use a 1/2" drill to do the job
since it still has no let-down clutching.
on the power subject, I would want 110VAC since the tower is just
outside the fascia of my house's North wall and at the same time, I
want about 25' of remote control cable so that I can stand off and
watch it go up or come down. so, that is what i am looking for in a
winch and any that will fit on a front bumper of a truck should work
as long as it has that let-it-down clutch capability. a LOT of them
do NOT !!! The bumper winches will do your job if you want 12vDC.
ok back to lurk to see what suggestions come out of the tower users here.
