Crane Hand Signals

Crane Hand Signals
5/11/2016 2:01:04 PM

In today’s age of increasing safety regulation, it’s essential that your signal person and crane operator communicate clearly and efficiently. If there is any confusion between the two, the chances of an on-site accident are heightened, which can lead to damaged equipment, injured team members, and raised costs.

The Occupational Safety and Health Administration (OSHA) issued standardized crane operation hand signals for use on the job. Here are fifteen of the most important crane hand signals, so you can better understand these techniques, and teach them to your crane operators:

Stop

Extend one arm with your palm down horizontally, and out to the side. Then, swing your arm up and down.

Emergency stop

Extend both of your arms out, palms down, to either side of your body. Then, swing both arms up and down.

Lower

Lower your arm and index finger down towards the ground. Next, make small circles with your arm, hand, and index finger.

Lower boom

Extend your arm horizontally to the side. Then, point your thumb down while keeping the rest of your fingers together.

Hoist

Extend your arm up over your head with your index finger pointing straight up. Then, move your hand and finger in small circles.

Dog everything

Clasp your hands together at waist level.

Trolley travel

First, hold one hand up with your fingers closed together, and your thumb pointing in the direction where the trolley should move. Next, move your hand back and forth in the direction you want the trolley to go.

Swing

Extend one arm out to your side. Then, point your finger in the direction the boom is supposed to swing.

Raise boom

Extend one arm out to your side. Then, point just your thumb upwards, while keeping the rest of the fingers on that hand close together.

Extend telescoping boom

Put your hands in front of you at waist level. Then, point just your thumbs outward, while keeping the rest of your fingers on each hand closed.

Retract telescoping boom

Put your hands in front of you at waist level. Next, point just your thumbs at each other, while keeping the rest of your fingers on each hand closed.

Raise the boom and lower the load

Extend one of your arms to the side with your thumb pointing upwards. Next, continuously open and close your fingers on that hand, while the load should continue to move.

Travel/Tower Travel

Extend your arm out horizontally with all of your fingers pointing upwards. Next, move your arms out and back to make a pushing motion in the direction you want the tower to travel.

Use main hoist

This action can be applied to any of the hand signals mentioned above. First, tap the top of your head with one hand. You can signal any of the other crane operations with your other hand.

Move slowly

This action can be applied to any of the operations mentioned above, as well. To make any of the aforementioned actions happen more slowly, put your unused hand above the hand that’s making the motion.
