The Problem Isn't You. It's How It Was Explained.

You're looking at a load chart on paper: boom lengths across the top, radii down the side, a bold line, a page of notes. And you don't know where to start.

The manual explains it in paragraphs. Configuration on one page, deductions three pages later, the quadrant tucked into a footnote. Nobody gives you the order.

Configuration → Quadrant → Boom length → Radius → Gross → Deductions = Net capacity

In this book, that same chart is one page: six boxes in a row, configuration, quadrant, boom length, radius, gross capacity, deductions, and one arrow to net capacity.

Same with the rest: the 20-foot rule, sling angles, load weight, the stop signal, the shift inspection. Each one has its own page.

You see the steps, you run them in order, and you get to the number without flipping back through the manual.

Same Topic, Two Ways to Study It

THIS
  • The manual: line after line
  • Crane types explained only in words
  • You walk into the exam with doubts
Rated capacities shall be determined from the manufacturer's load chart for the configuration in use. Prior to reading the radius, the operator shall verify outrigger position, working quadrant and boom length. Unless otherwise noted, the capacities listed include the weight of the hook block, slings, rigging hardware and any stowed or erected attachments, and such weights shall be deducted to obtain the net load that may be lifted. Refer to the chart notes for structural versus stability limitations, which may be indicated by a bold line or shaded area and which vary by configuration.

One Page, One Topic, All Clear

Think of it this way:

You're in the seat and the lift director gives you the pick: 60-foot radius, jib stowed, load over the side. You need a capacity, and you need it right.

In the book you open the 6-steps page and it's drawn: six boxes in order, from configuration to deductions, ending in net capacity.

1926.1419: three cases require a signalperson; anyone can give the stop signal.

Same for the 20-foot rule, load per leg, the stop signal, the shift walkaround and the LMI: each one on its own page.

Mobile Crane Operator Illustrated is 66 pages in 8 parts, all drawn, and it closes with an exam-day review: the 6 steps on one card, numbers to know cold and a signals self-test.

What you see drawn, you don't have to memorize.

If the written didn't go your way the first time, it's rarely the machine. Here the load chart is 6 steps, always in the same order, with the rule behind every number.

Recertification coming up

Your hands know the machine. The book puts the paper side back in order: deductions, sling angles, Table A, inspections.

Frequently Asked Questions

Is it for me if I've run cranes for years and just need to recertify?

Yes. It doesn't teach you to run the machine; you already do that. It puts the paper side in order: load charts, rigging math, signals and the rules, one topic per page, every number with its OSHA or ASME citation. Your manufacturer's manual covers your crane, and free videos each show a different method. This gives you one order you run on paper, the same way every time. It also works if you're a rigger or signalperson moving into the seat.

Where does the content come from?

From OSHA 29 CFR 1926 Subpart CC (including the Appendix A hand signals) and ASME B30.5, B30.9 and B30.26. Every number comes with its citation. The load chart in the book is fictitious and made for practice.

Is it official material?

No. It's independent study material, written for mobile crane operators in the United States and checked against OSHA 29 CFR 1926 Subpart CC and ASME B30. It isn't published, endorsed or approved by OSHA, ASME, NCCCO, any certifying body or any crane manufacturer, and it doesn't reproduce exam questions.

Does it replace a training course?

No. It doesn't give you a certificate or a card, and it doesn't replace training, certification by an accredited body, your employer's evaluation, or your crane's load chart and operator's manual. It's for studying and reviewing the paper side.

Are the practice questions the ones on the exam?

No. They're written for this book, in exam style, with the answers explained. They aren't official questions from any exam.

When and how do I get it?

The book and the 2 bonus books come as PDFs by email, to the address you enter at checkout.

Do I have to pay every month?

No. It's a one-time payment.

Can I have it on paper?

Yes. It's a printable PDF: print the whole book, or just the pages you want, like the 6-step card for your truck.

How does the refund work?

You have 30 days. We refund everything if the file won't open, if the book isn't what you see on this page, if you were charged twice or if the email doesn't arrive: just email us.

Before You Close This Page

No more rereading the manual with nothing sticking.

Load charts, sling angles, the 20-foot rule: you see them drawn.

You walk into the exam knowing where everything is.
