NCCER Crane Signal Person & Communication 2

Question 1

To signal 'lower the load,' the signal person should:

Accepted Answer

Arm extended downward, forefinger pointing down, moving hand in small circles

Answer

The lower signal mirrors the hoist signal but points downward — forefinger circling while pointing down indicates continuous downward motion.

Question 2

How does the signal person indicate 'swing' to the crane operator?

Accepted Answer

One arm extended, forefinger pointing in the desired direction of swing

Answer

The swing signal uses one arm extended with the forefinger pointing directly in the direction the load should travel.

Question 3

The hand signal for 'raise the boom' is:

Accepted Answer

Arm extended, fingers closed, thumb pointing upward

Answer

Raising the boom is signaled with arm extended, fingers closed, and thumb pointing upward — the thumb distinguishes it from the hoist signal.

Question 4

What does the signal for 'extend boom' (telescoping) look like?

Accepted Answer

Both fists in front of body with thumbs pointing outward

Answer

Extending the boom is signaled with both fists in front of the body with thumbs pointing outward, indicating outward extension.

Question 5

How is the 'move slowly' signal given in crane operations?

Accepted Answer

Hold one hand stationary below the other hand that is giving the motion signal

Answer

'Move slowly' is indicated by placing one hand below the other hand giving the motion signal, telling the operator to execute at reduced speed.
