Cami Automotive Larry S.(What I liked most about the seminar was...) Plant tours.
North AmericanStainless Rex C.(What I liked most about the seminar was…) Well instructed.
Gerdau Ameristeel Mike M.(What I liked about the seminar was…) Learning about the mechanics as well as built in safe guards on cranes. I thoroughly enjoyed the course. I have operated
the mill crane off and on for 20 years. I learned more about cranes in the 2 1/2
day course than I have in previous years. Instructor did a great job.
