Sample Video Transcript
There are several standard hand signals that apply to all crane types. The most common hand signals are: • Hoist, or raise, the load – with your forearm and index finger pointing up, move your hand in a small horizontal circle • Lower the load – with your forearm and finger pointing down, move your hand in a small horizontal circle. Keep your arm away from your body so it is easy to see your hand. • Swing the boom – extend your arm and point your finger in the direction you want the boom to swing • Move slowly – use one hand to give any motion signal and place your other hand above to indicate you want the movement to be done slowly. For example, hoist slowly.
