The function of an overload protection device for a stage electric hoist is to prevent the hoist from operating under excessive loads, thereby ensuring the safety and reliability of the equipment and the personnel operating it. Here are the specific functions of an overload protection device:

Load Monitoring: The device continuously monitors the load that the hoist is carrying. It senses the weight or force exerted on the hoist and compares it to the hoist's rated capacity.

Overload Detection: If the load exceeds the rated capacity of the hoist, the overload protection device detects this condition. This detection is usually based on electrical signals or mechanical strain sensors that measure the load.

Automatic Shutdown: Upon detecting an overload condition, the device automatically shuts down the hoist's motor or power supply. This prevents further strain on the hoist's components and avoids potential damage or accidents.

Warning Indication: Many overload protection devices are equipped with warning indicators, such as lights or alarms, to alert operators when an overload condition is detected. This allows operators to take immediate action to address the issue and prevent further overload.

Protection of Critical Components: The overload protection device helps protect critical components of the hoist, such as the motor, gears, and brakes, from excessive wear and tear. By preventing overload, it extends the lifespan of these components and reduces the need for frequent repairs or replacements.
