What safety protection devices are on the electric hoist

Because of its small size, simple structure and convenient use, electric hoists are used in many fields, such as industrial and mining plants, supermarkets, warehouses, etc. Now there are many types of electric hoists, as well as mini electric hoists suitable for home use. You can choose according to your actual situation. In addition to the above, the safety design of electric hoist is especially important. Today we introduce the safety protection devices of electric hoists.

1. Limit switch: It is located under the electric hoist and directly above the hook. When the wire rope reaches the position of the limit switch, the electric hoist will automatically cut off power to ensure that the wire rope will not come out.
2. Reverse phase protection device: It is a protector of the power supply. When the power supply is connected incorrectly, the electric hoist will automatically control the circuit to protect the motor from burning out and avoid motor damage caused by improper human operation.
3. Emergency stop button: It is located on the remote control of the electric hoist. It belongs to the red circular button. For emergencies, users can press this button to implement emergency stop operation.

There are other details of safety design of electric hoist, which will be introduced in future articles. Only by understanding and mastering the overall design function of the electric hoist, and being able to skillfully apply the operation, can the electric hoist be better used, and our personal safety can be better protected.
