The working principle of the control box of the stage electric hoist is that when the lifting or lowering button on the control box is pressed, the control circuit sends forward or reverse instructions to the motor according to the instructions, and the motor drives the gearbox gear and transmission chain to move, thereby achieving the lifting or lowering of the heavy object.
At the same time, the control box also has safety protection functions such as overload protection, short circuit protection, phase loss protection, and voltage loss protection to ensure the safe operation of the equipment.
In addition, the control box can also limit the lifting or lowering height of heavy objects by adjusting the limit switch, thereby achieving precise control of the position of heavy objects.
Different types of control boxes may have different operating methods and control circuits, but their basic principles are similar.
According to different needs, different control boxes can also be customized, such as adding remote controls, adding remote controls, and receivers.
