With the hand stretched out in front of the body, point the fingers upward while pressing in and out in the direction of motion. You may also sign telescope in, by holding your hands out in front of you with your thumbs pointing inward and your fists locked at waist level.Ĭranes may be moved in any direction, and the operator can be instructed on the safest manner to do so by using hand signals. To sign telescope out, hold your hands at your waistline with your thumbs facing outward and your fists closed. In addition, telescopic cranes, which have extendable and retractable booms, have their own set of boom instructions. You may also indicate to lower the boom and hoist load by stretching your arm outward and pointing your thumb downward while opening and shutting your other fingers. To indicate raise the boom and lower load, hold out one arm, point the thumb skyward, then open and close the other fingers. To maintain the crane within its safe working limitations, you may need to utilize a combination of orders to account for the load radius changing as the boom is raised and lowered. Extend one arm vertically, point a finger toward the ground, and make little clockwise circles with the hand to indicate a lower load. Extend one arm vertically, pointing toward the sky, and make little clockwise circles with the hand to indicate a hoist load. There are two common load signals, hoist, and lower load. Load signals indicate to the crane operator whether the load should be raised or lowered using the crane’s hoist, which is a long chain with a hook that attaches to the load.

Regardless of whether you’re working with a tiny carry deck crane or a massive all-terrain crane, or even the biggest crane in the world, you’ll need to know some basic crane hand signals.Ĭrane operation relies heavily on stop signals, which allow a signal person to rapidly convey the requirement to halt movement and activities.Įxtend one arm out to the side, palm down, then bring it in toward your chest and out to the side again to signal a stop. This is a guide on the fundamentals of how to use crane hand signals, including a few signs unique to telescopic, crawler, and tower cranes. Given that the BLS reports that more than 60% of construction accidents occur during the first year of a worker’s employment, it is necessary to provide training at the start. The Occupational Safety and Health Administration (OSHA) mandates that anybody designated as a signal person fulfil particular credentials and be reviewed by a trained professional. Learning the standard crane hand signals allows a signal person to safely guide a crane operator to do tasks such as raising and lowering the boom, hoisting and lowering the cargo, moving the load horizontally, and stopping the crane in an emergency. The safe and efficient movement of big loads on a building site relies heavily on the use of cranes, and crane hand signals are an integral element of this.
