Overhead Traveling Crane Operator Textbook KOBELCO Kobelco 2022, 2nd Edition, 12th Printing Special Education Skills Training Test Certification License Certificate Factory Industrial Construction Building How about for preparation, review, retraining, or checking important points? I obtained it two years ago, and I don't think the content has changed since then. Since unauthorized reproduction and use of the content and images in this textbook are prohibited, I cannot post photos, but I have underlined the parts that were said to be on the exam in red. I was fighting sleep while drawing the red lines, so some of the red lines are wavy and messy. Thank you for your consideration.
