Question 1 of 27070

The signal man assisting the crane operator first taps the top of his head with his fist and then proceeds to use regular signals. This is the signal to __________.

🔍 Key Concepts

• Standard crane hand signals used in marine cargo operations • The specific meaning of tapping the top of the hardhat/helmet before other signals • Differences between signals for choosing a line (whip/auxiliary/main) vs signals for speed (slow/stop)

💭 Think About

• Think about why a signal man would give a brief, unique signal before continuing with normal hoist/lower signals. • Ask yourself: is this gesture more likely to be choosing which line to use, or setting a general condition (like speed or caution) for the operation? • Consider which of the listed options would logically apply to all the regular signals that follow, rather than to just one specific movement.

✅ Before You Answer

• Identify in your memory or study materials what tapping the top of the hardhat with a fist specifically indicates in crane operations. • Check which options refer to selecting a particular line and which refer to how the crane should operate (speed/hoist selection). • Verify that the meaning you choose makes sense as an instruction that would logically come before ‘regular signals’ are given.
