   Use a DC winch with a speed control or "soft start" or get all fancy   
   schmantzy with a hydraulic winch - - - - -   
      
   ---------------------------------   
   I was happy with the hoisting speed and positioning control of a 1 ton   
   manual chainfall. It lifted the track and sawmill components for assembly,   
   positioned and rotated the logs, and moved all the lumber I cut. When not in   
   use the hand chain was stored in the farm bucket, hung from the hook. The 2T   
   chainfall lifted the heaviest logs but got little use otherwise because it   
   is so slow.   
      
   I suppose a jogging or inching mode for an AC electric hoist could be added   
   with a variable time delay and SSR relays, as I did for my spotwelder.
