This guide will explain about different hand signals for crane operators
Cranes are very important in almost all the industries. The safe operation of cranes is very important, to avoid accidents and to make the workplace safer. Safety must be the priority of all the industries and should come before all other matters. At times it is important to communicate with the operators to guide them effectively and to mitigate incidents.
Since the factory or production area is very noisy, it becomes very difficult to communicate with the operators. Other than noise, the attention of the operating person can also deviate if other communication methods are employed. In such cases, it becomes essential to guide the crane operators using hand signals and gestures.
In order to do so, there are two important things that need to be addressed:
- The crane operator must be aware of all the different signals and should be able to respond when the crew member or nearby worker tries to guide him/her.
- The workers and crew on the work site must be accustomed with and educated on all the important hand signals and gestures, so that they may be able to provide directions to the operator.
The hand signals are universal in nature and can be used everywhere, regardless of the location of the work site. This article is focused on providing detailed information regarding hand signals for crane operators. The definitions and explanations of different hand signals are 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.
When the crane trolley needs to move along its bridge, the signal to travel is used. The signaler stands sideways to the operator’s view facing in the direction the crane needs to travel, and puts up the hands as if to push the crane in the intended direction.
Dog everything, or pause, can be useful if the situation changes, if there is a need for further instructions, or if there is the potential for danger. The signal for dog everything is to place the signaler’s hands clasped in front of the stomach.
