Hand Signal Guide For Crane Operators
This guide explains some common crane operator hand signals
Crane Operator Hand Signal Guide: Cranes are marvelous machines and it takes a lot of skill and expertise to operate them efficiently. In addition to that, operating cranes also requires patience and attention. It is not only the operator, though, that needs to be attentive. The workers or crew with the operating personnel also need to be careful and contribute to the safe operation of the crane.
The industry or factory is a noisy place and you cannot communicate while operating the crane. So, there must be a signal person who should guide the operator using numerous hand signals. Hand signals are an efficient way to guide the operator in order to ensure safe crane operation.
We have different types of cranes available for your needs. However, the signals that are used to guide the operators are the same and this guide explains them in detail.

To hoist, or raise the load, the signaler stands with his/her right arm bent 90 degrees upward. From there, the signaler points his/her finger upward and and turns it around from the elbow in a counter-clockwise motion.
Lowering the load is where the signaler places his/her right arm pointing straight downward to the side by the hip, points the finger off to the right, and turns the finger around from the elbow in a counter-clockwise fashion.
Use Main Hoist
There are going to be occasions when the main hoist is necessary for its greater strength. In these instances, the signaler cocks their right arm outward and bends their elbow outward, which allows the signaler to tap on their hard hat with their closed hand as if they were knocking on a door.
To lower the boom is the reversal of the signal to raise the boom. The signaler begins with the right arm outstretched to the side. From there, they point their thumb downwards.
Lower the Boom and Raise the Load
Lowering the boom while raising the load involves a similar signal to the previous boom lowering signal. The signaler begins with the right arm outstretched to the side, and the thumb pointing downward. The signaler then opens and closes the hand, extending and retracting the fingers repeatedly, to indicate this dual motion.
Raise the Boom and Lower the Load
Raising the boom while lowering the load is also similar to its original boom raising motion. The signaler begins the operation by extending the right arm outward to the side, and extending the thumb upward. From there, the signaler extends and retracts the fingers of the right hand, to indicate the dual motion required of the crane.
