This guide will explain different hand signals for crane operators
Hand Signals for Crane Operators: Cranes are very important for the industry. They are efficient, rugged and reliable machines which are used heavily in the construction sector. Crane operators are trained and certified professionals who have the ability to handle these machines with skill and efficiency. Sometimes, the crane operators require some assistance from the workers on site, in order to maneuver the crane and to lift and load objects without causing any incidents.
Communication in such cases becomes vital and it can be a bit troublesome to communicate effectively in the plant area or project site; primarily due to the high noise prevalent in the premises. It then becomes imperative that the crane operators be guided by the use of hand signals and gestures.
In order to properly convey the signals, the workers or crew on site must be familiar with different hand gestures that are used universally. Similarly, in order to understand the messages, the crane operator must be equally versed in the signals.

The explanation regarding different hand signals for crane operators is as follows:
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.
Use Whip Line
On some occasions, the whip line or fast line may be preferable to the main hoist. To signal using the whip line, the signaler places his/her left arm horizontally across the front of the body, palm upward. The signaler then makes a forward-facing fist with the right hand, and puts the right elbow into his/her left palm in front of themselves.
To raise the boom, the signaler begins with the right arm outstretched to the side. From there, the signaler points the thumb upward.
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.
