Official GMM hand model
Al.. I'm just used to the hand control I have over tools but I do understand using air power is the only real way to go. You should have seen the 4 inch drive impack wrench we used on the turbine decks to loosen and tighten big stuff. It was made by Ingersol Rand but we called it.. The Widow Maker and for good reason. It required a crane to lift it. then 6 air supplies feeding a huge manifold. then 3 big men on each of the 2 handles. We duct taped the on off located on one of the handles because nobody could use it and hold on. It was an 8 man job working that tool. One in the crane. One to open the 1 1/2 inch air line from the manifold where 6 3/4 inch air lines fed and 3 men on each handle. The sockets weighed as much as 80 lbs each.. the widow Maker was a good name for that monster.
