Overhead Crane Electrical Maintenance - 3 Days
In this 3-day crane training course, students will learn how to perform electrical inspections and preventive maintenance procedures.
Paper Converting John R.(What I liked most about the seminar was...) Very informative and interesting.
Los Alamos Jose H.(What I liked most about the seminar was…..) Liked it all. Instructor was great.
Enjoyed class.
Gerdau Ameristeel Robert H.(What I liked about the seminar was….) Learning more about mechanics on
cranes, Magnetorque™ and wire rope inspections, etc. Instructor did a great job instructing the class. It would be wise to put every crane operator thru this course, because of safety reasons. The more crane operators receive more knowledge about cranes the better they would be.
Timet Scott B.(What I liked most about the seminar was…) Rigging and crane safety portions.
Course was very well structured and informative.
Los Alamos David R.(What I liked most about the seminar was…..) Informal. Very good job.
