This course offers in-depth mechanical and electrical training for maintaining and troubleshooting overhead crane systems, focusing on both safety and operational efficiency. Students will gain hands-on experience in diagnosing root causes of abnormal crane tracking and wear, as well as learning proper procedures for component replacement and preventative maintenance. The course also covers crucial electrical elements, including various A.C. crane control types, motor operation analysis, and essential protective circuits. Through rigorous testing, troubleshooting, and maintenance practices, participants will build the skills needed to enhance crane system reliability and ensure safe operation standards. Upon successful completion, participants will earn a certificate of course completion and contribute to the course evaluation to further enhance training effectiveness.
