Re: (ET) lift motors, almost, but not quite....

Joel,

Nice setup.  If you double the strap by using a lower pulley then back up 
to the winch it will increase it's loadlifting capabilities (bad) but half 
it's speed (good).  I'd love to see pics.

I did - I happened to have a Superwinch 1500 left over from another 
application and I bolted it to the front 'grille' of the E-15.  I used new 
tubular nylon webbing instead of cable, and I'm running it on 12V, but 
through the main disconnect switch (My OEM disconnect switch with fusible 
link is still in good shape, knock on wood) and using the switch that came 
with the winch that switches both leads to the winch to get FW and REV.  
Or in and out if you prefer.  I can post a picture or two somewhere if 
folks are interested.

The main problem (besides the fact that it sticks out on the front) is 
that it is too fast and powerful - I have to be careful to use something 
disposable between the webbing and the attachment on the deck or dozer 
blade because it'll rip the fitting off otherwise if I'm not paying 
attention and still have my finger on the switch when the implement hits 
the stops at the top.

But I am looking forward to having it zip the snowblower up and down...

I'm also thinking of cutting a hole in the side of the front battery box 
for the end of the winch to stick out so I can mount the thing on the 
_inside_ of the grille.  I've got plenty of room in there above the 
charger since I did the Alltrax conversion and the big resistors are gone. 
 I'd also need a fairlead through the grille, although maybe over the top 
would be best... I've been toying with the idea of mounting the fairlead 
on a stiff spring somehow so that I can see the thing deflect and get my 
finger off the switch before things start breaking and pulling out and 
such.  But I haven't gotten the right idea in my head for it yet.  Ooh ooh 
I think I've got it - something like a chain tensioner on a bike 
derailleur, with pulleys to guide the webbing in an S shape, and a flag 
that pops up when the load overcomes the spring tension.  Better yet, a 
switch that cuts out the winch when the load overcomes the spring tension.

Hmm, more things to try, and even less time to try them in than ever 
before!

*sigh* So I guess our options are either find motors, somehow rebuild 
them, rewind them, or go in another direction. Anyone ever replaced their 
lift with a small 12 volt winch?
