How should you signal the crane operator to raise the boom and lower the load?

🔍 Key Concepts

• Standard crane hand signals used on U.S. worksites (often from OSHA/ASME charts) • How thumb direction relates to boom movement (up or down) • How opening/closing the fingers often indicates hoist or lower the load

💭 Think About

• Which part of the signal usually shows what the boom should do (raise vs lower)? Look closely at the thumb direction. • Which part of the signal typically shows whether the load should move (hoist vs lower) and for how long? • Among the options, which one combines a boom command and a load movement command at the same time?

✅ Before You Answer

• Verify which choice includes a clear thumb direction (up or down) to indicate boom movement. • Verify which choice includes a repeated hand or finger motion that would indicate continuing movement of the load. • Eliminate signals that look more like a stop/hold or attention-only signal, rather than an active movement command.

Place both fists in front of your body with thumbs pointing toward each other.

Extend arm with the thumb pointing up, and flex the fingers in and out for as long as the load movement is desired.

Extend arm with the palm down and hold this position rigidly.

Clasp hands in front of your body.
