Agree with John 100%. Spent a lot of time when I first got into the trade in a very large machine shop. We used mostly SJ drops due to machines getting moved even when they were supposed to be permament and saw a lot of conduit damage from fork lifts ETC. The SJ being flexable held up better. We'd pipe to directly over the machine, add a box and then make an SJ drop.
What bothers me was seeing SJ tie wrapped to trusses and in places down low subject to physical damage.
