In this three day crane training course, students will learn how to perform electrical inspections and preventive maintenance procedures.
Trinity Rail Gale B.Instuctor was very good.
Los Alamos Paul S.(What I liked most about the seminar was…..) Everything was presented well.
Gerdau Ameristeel Wayne J.(What I liked about the seminar was….) How much knowledge that instructor
shared. Instructor did a great job. He has a great deal of knowledge about cranes and the components. He (did) good on his presentations and should be recommended. This was one of the better class that I've taken with a good instructor.
Preifert Mfg Travis P.(The instructor) did an excellent job and we would love to have him back any time.
Nucor Steel Scott W.(What I liked most about the seminar was…) The experience of giving an oral presentation to the class.
