Course information
In this three day crane training course, students will learn how to perform electrical inspections and preventive maintenance procedures.
Harsco Rail Andy M.(The instructor) really made the course interesting where it could have been boring.
Lockheed Martin Seth P.(What I liked most about the seminar was…) The proximity of the shop-we just
walked out to look at things that were otherwise difficult to explain. The hands on. Also the tours on Thursday were fantastic. Particularly the guys who toured us through the Winsor and Watertown facilities were extremely knowledgeable and
took their time.
Tilden Mine Rob R.(What I liked most about the seminar was…..) The brake portion.
Caterpillar Brian D.All the info was very interesting.
Wheelabrator Luis A.(What I liked most about the seminar was…) Visiting all the facilities and seeing
everything they do.
This crane training course highlights electrical maintenance procedures for all types of A.C. crane controls including A.C. full magnetic, stepless and adjustable frequency drives. This crane course is considered the basic orientation to electrical maintenance.
