Stage electric hoist load capacity test: a key link to ensure stage safety and excitement

　　1、 The Importance of Load Capacity Testing

　　(1) Ensure safety

　　The stage electric hoist needs to carry various weights of equipment and props during use. If the load capacity is insufficient, it may cause serious consequences such as equipment falling and personnel injury. Through load capacity testing, the actual load-bearing capacity of the stage electric hoist can be accurately understood, ensuring safety during use.

　　(2) Ensure the quality of performances

　　Stage performances require extremely high stability and reliability of equipment. If the stage electric hoist malfunctions or becomes unstable under load, it may affect the smooth progress of the performance and even disrupt the overall performance effect. Load capacity testing can detect potential issues in advance, ensuring the quality and effectiveness of the performance.

　　(3) Extend equipment lifespan

　　Proper load capacity testing can help users understand the ultimate load-bearing capacity of stage electric hoists, avoiding overuse and overloading situations. This helps to extend the service life of the equipment, reduce maintenance costs and replacement frequency.

　　2、 Methods for load capacity testing

　　(1) Static load testing

　　Static load testing is to suspend a certain weight of load on a stage electric hoist, maintain it for a period of time, observe whether the structure of the hoist has deformed, whether the chain is loose, and whether the motor is running normally. This testing method can verify the load-bearing capacity of stage electric hoists in a stationary state.

　　(2) Dynamic load testing

　　Dynamic load testing is conducted during the process of lifting and moving loads on stage electric hoists. By simulating actual usage, observe the running speed, stability, braking performance, etc. of the hoist. This testing method can provide a more comprehensive understanding of the performance of stage electric hoists under dynamic conditions.

　　(3) Gradually increase load testing

　　In order to more accurately determine the load capacity of the stage electric hoist, a testing method of gradually increasing the load can be adopted. Starting from a smaller load, gradually increase the weight until the hoist reaches its maximum load-bearing capacity or malfunctions. During the testing process, it is necessary to closely observe the various performance indicators of the gourd and record the testing data for each stage.
