It looks somewhat similar to the manually operated Kurt power unit that I adapted to my mill. At first I questioned the strength of the cheap little CP (Chicago Pneumatic) butterfly impact they used, but after lingering a little too long on the "tightening" side of the lever a couple of times - I worried about if I was ever going to get the drawbar loose again. 
Those little buggars will cinch up a drawbar a lot more than you think.
