Electric hoist is a small and light lifting equipment integrating motor, reducer, and electric control box. The most common safety device is \”overload limiter\”.

At present, the hoist overload limiter commonly seen in the market works based on the feedback of the electric hoist lifting structure, which is fed back to the instrument for collection, reading, comparing and judging, and finally displaying the current weight and performing corresponding work on it. The condition indicates that if the rated weight exceeds the rated weight, it is necessary to cut off the electric hoist hoisting circuit, so that the electric hoist stops lifting heavy objects, so as to protect the safety of the electric hoist and the operator.

So when the electric hoist overload limiter is damaged or needs to be replaced abnormally, how should we select it?

In view of the electric hoist structure, the overload limiter is mainly divided into one-piece type and split type. The integrated electric hoist overload limiter sensor is bundled with the display instrument, and the main sensor used is the side pressure sensor. When selecting an integrated overload limiter, pay attention to factors such as hoist load, wire rope magnification, wire rope diameter and available power supply. The advantages of the integrated electric hoist overload limiter are easy installation and low price. Under normal circumstances, it is suitable for electric wire rope hoists.

Split type electric hoist overload limiter generally uses shaft pin sensor, S-type sensor or plate-ring sensor. When selecting overload limiter, consider the load of the electric hoist, chain diameter and available power supply, etc., but also need to provide installation The parameters of the sensor have avoided the situation that cannot be used normally after purchasing the overload limiter. The advantage of the split electric hoist overload limiter is that it is free to take power and can solve the safe overload problem of the more complex electric hoist. It is more used in electric chain hoists.

Because of its small size, light weight, and convenient operation, electric hoist has become a necessary lifting equipment for industrial and mining enterprises, storage docks and other places. In the process of using the electric hoist, it is necessary to lift heavy objects of different tonnages. In order to use safety, it is necessary to perform real-time monitoring of the work in time, and make corresponding instructions when abnormalities or special situations occur. In case of full load and overload, the overload limiter will work. main effect. If you have any questions about electric hoist overload limiter, please contact us.
