[CAUT] Getting the plate out

[Greg Newell]

Tom,
         This is an important post to me. Thank 
you for taking the time! I'd like to ask if the 
jerky feel from motor driven hoists is present in 
air motors too. I understand that there is 
difficulty with the electric units but I wasn't 
aware of the same problem with air driven units. 
Also, what is a "differential" chain hoist? Thanks again!
