How should you signal the crane operator to lower the boom?

🔍 Key Concepts

• Standard crane hand signals for "lower boom" versus "lower load" • Difference between moving the boom angle and moving only the hook/load • How thumb or finger direction is often used to indicate boom movement in crane signals

💭 Think About

• Which part of the crane are you controlling when you talk about lowering the boom: the hook/load, or the boom itself? • Look at which options include a clear directional cue that specifically relates to boom movement, not just holding or clasping. • In standard crane signaling, how is the thumb often used differently from the forefinger when indicating boom actions?

✅ Before You Answer

• Identify which choices clearly show an up/down directional indication rather than a vague or static posture. • Check which signal is commonly associated with boom movement instead of hoist (hook) movement in standard crane charts. • Eliminate any options that do not involve an active, intentional gesture that could be seen easily from a distance.
