Overhead Crane Electrical Maintenance - 2 Days
This electrical crane maintenance training course highlights electrical maintenance procedures for all types of A.C. crane controls including A.C. full magnetic and adjustable frequency drives and is considered the basic orientation to electrical maintenance.
Ariel Safety & Training Jim M.It was appreciative that time was taken to answer questions. All questions were
answered with knowledge and skill. Reference material was well used to reinforce the "why" of what an overhead crane operator is responsible for.
Lafarge NorthAmerica James C.We were pleased with the training and saw an improved reliability of crane operations with the trained operators.
V&M Star Dan C.The course was very instructive and taught me things I did not know. It was well
worth the time.
Trane Richard B.Very good instructor, cares and understands the value of safety and what damage it
causes. (I liked…) the instructor’s knowledge and ability to listen and answer questions.
Phelps Dodge Charles A.(What I liked most about the seminar was…) Full involvement.
