Washington Standard Hand Signals for Cranes are a set of standardized hand signals used by crane operators and signal persons to safely communicate during crane operations. The signals are used to indicate direction, speed, and weight of the load being lifted. There are two types of Washington Standard Hand Signals for Cranes: the Up-Down Hand Signals and the Left-Right Hand Signals. Up-Down Hand Signals are used to indicate the direction of the crane movement and weight of the load being lifted. The signal person will use their arm to indicate the direction and weight of the load. If the arm is raised vertically, they are indicating the crane should raise the load. If the arm is lowered vertically, they are indicating the crane should lower the load. If the arm is raised and then lowered, they are indicating the crane should stop. Left-Right Hand Signals are used to indicate the direction the crane should move and the speed at which it should move. If the signal person moves their arm in a circular motion, they are indicating the crane should rotate. They can also indicate the speed of the crane's rotation by moving their hand faster or slower. If the signal person moves their arm horizontally, they are indicating the crane should move to the left or the right. They can also indicate the speed of the crane's travel by moving their hand faster or slower.
