[TowerTalk] hazer raising winch

[Kenneth Waites]

I am removing the worn winch that came on my 70' Glen Martin aluminum tower, and replacing it with a winch
that has a spool.  I want reliability first.  
I am finding it difficult to find a winch that will hold 70' or so of cable that I believe is 7/32".
I think the Dutton-Lainson DLB1500 would work, but mounting it on the reinforced tower base where the old winch 
was means I have to use a rachet handle.  This will make raising/lowering a VERY slow process.
 
I am looking for any better solution.  I am considering ATV 12v motorized winch solutions, but I have not found one that appears to have enough spool. Manual systems also are being considered, it they make it easy enough.
 
Does anyone have some suggestions here?
