Crane Signal Simulator

Yes. Every tile is a signal from the Standard Method chart — Appendix A to 29 CFR 1926 Subpart CC — drawn the same way as in our hand-signal drill: hoist, lower, swing, raise and lower boom, extend and retract, move slowly, stop, emergency stop and dog everything. 1926.1419(c) makes that chart mandatory whenever hand signals are used.

Because it is the rule. Under 29 CFR 1926.1408, for a line up to 350 kV no part of the crane, the load line or the load may come closer than 20 ft unless the line has been de-energized and grounded, or the voltage is confirmed and the Table A clearance is kept. Power-line contact is one of the leading causes of crane deaths, so the game treats the zone the way a site should.

Stop lets the operator bring the motion down — the crane decelerates and the load keeps swinging. Emergency stop halts every motion at once. Level 5 puts a worker under the load path: only Emergency stop saves it. On a real site the operator must obey an emergency stop from anyone, under 1926.1417(y).

When the load goes where the operator cannot see it, the signal person becomes the operator’s eyes, usually by radio. Radio signals arrive with a lag and there is no second look, so you learn to signal Stop early. 29 CFR 1926.1420 covers radio and other electronic signals, including testing the channel before the lift.

No — it is practice. A signal person is qualified under 29 CFR 1926.1428 by an employer or a third-party evaluator, with an oral or written test and a practical test. Our Crane Signal course prepares you for both and issues a certificate.
