(What I liked most about the seminar was…) The rigging charts.

REC Silicon Jim B.

(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.
