1. Never Mix or Modify Standard Signals

Stick to approved signals at all times. Don’t create any shortcuts or personal variations.

2. Avoid Signaling from Blind Spots or Unsafe Positions

If the operator can’t see you, they can’t respond correctly. Always choose a location that is both visible and safely out of the equipment’s way.

3. Don't Rush Signal Sequences or Skip Confirmations

Rushing signals can cause errors. Each movement should be clearly communicated and confirmed before the next step begins.

Basic Movement Signals (Hoist, Lower, Swing)

These signals control the most common crane movements:

Hoist: Arm extended upward, finger pointing in a circular motion

Lower: Arm extended downward, finger pointing in a circular motion

Swing: Arm extended outward, pointing in the direction of the swing

Common Mistake: Moving too fast or not holding the signal long enough can confuse the operator. Signals should be steady and easy to read.

Emergency and Stop Signals

Emergency signals must be clear and immediate to bring work to a complete stop:

Stop: Arm extended with palm facing downward

Emergency stop: Both arms extended with palms facing downward

These signals override all other commands. Every worker on-site should recognize them and respond quickly.

Crane Boom Operation Signals (Raise, Lower, Extend, Retract)

Boom signals control the crane’s reach and positioning:

Raise boom: Arm extended with thumb pointing upward

Lower boom: Arm extended with thumb pointing downward

Extend boom: Both hands moving away from each other

Retract boom: Hands moving toward each other

Distance and visibility matter here. The signal person should always position themselves where the operator has a clear line of sight.

Key Differences: Lineman vs. Substation Technician Comparison
