As a new type of industrial product, the chain hoist integrates various international advanced technologies and has the characteristics of large lifting tonnage and flexible operation. In addition, the chain hoist also has many protection mechanisms to ensure that the equipment can reduce the degree of damage to the equipment in the event of a failure.

1. Short circuit protection
The chain hoist has a short circuit protection function. This protection unit can cut off the power supply in time when a circuit fails, so as to minimize the damage to the equipment.

In the daily use of chain hoists, sometimes due to voltage instability, instantaneous voltage fluctuations will cause the current to increase instantly, exceeding the current that the equipment can withstand, and the short-circuit protection device can cut off the power supply in time to ensure that the equipment can operate normally and stably.

2. Loss of voltage protection
In bad weather, the power supply will be cut off and the voltage will increase. The loss of voltage protection can timely cut off the hoist motor from the power supply to prevent the voltage fluctuation from damaging the equipment.

3. Overheat protection
When the chain hoist is running, it will generate a lot of heat, causing the body temperature to rise sharply. At this time, the overheat protection mechanism is particularly important.
When the body temperature is too high, it will not only damage the electrical components inside the equipment, but also threaten people's lives. However, the overheat protection mechanism can cut off the power supply in time when the body temperature reaches the mature limit, and then connect the power supply when the equipment temperature drops to normal temperature to ensure that the equipment can operate normally and stably.

4. Load limit protection
Chain hoists have a mature capacity for cargo, and load limit protection is to avoid damage to the equipment due to overloading of the lifting cargo. There are many reports in the news about cranes that have injured people due to the breakage of wire ropes due to overloading of lifting cargo. Therefore, the load limit protection mechanism has a very important impact on the normal operation of the chain hoist.

5. Phase sequence protection
Under normal circumstances, there are clear regulations on the wiring method of the chain hoist motor. If the wiring method of the motor is confused due to certain objective factors, resulting in the chain not working normally, the phase sequence protection plays a big role. It can adjust the line layout method automatically when the wiring is confused to ensure that the equipment can operate stably and efficiently.
For the time being, I will introduce the relevant information about the chain hoist to you here. I hope that through this information, you can have a clearer understanding of the protection mechanism of the chain hoist.
