Nowadays, in China's lifting equipment production industry, electric chain hoist is a light and small lifting product. It has the advantages of small size, light weight, high strength and reasonable price. It is especially suitable for low construction height and space. Lifting and handling homework in small professional situations. A common check for the electric chain hoist lifting function is the quality block loading method which contains both stable and dynamic loading.
When the electric chain hoist is not improved, the quality of the test product is 1.5 times the rated weight, and the stability function is determined for a few minutes. When the electric chain hoist is raised, the measured product starts from the rated lifting weight and slowly participates in the quality block until the chain of the electric chain hoist is slipped. Record the pressure value and the displacement point at this time, and you can Measuring the limit point of the electric chain hoist is a dynamic loading.

There is no doubt that the quality block loading method is effective for the stable loading test of the electric chain hoist; and its dynamic loading is not suitable, which is mainly because the quality block loading belongs to the class loading, and the cause of the fault is large. . In addition, the effectiveness of such a test is also low. With the continuous growth of hydraulic control techniques and microcontroller technology, the completion of the force control system has also become simple and easy.
