The Importance of Trial Pulling Stage Gourds

　　1、 Steps and methods for trial pulling

　　(1) No load test pull

　　Firstly, conduct a no-load test pull, which means not attaching any heavy objects and only operating the stage hoist to perform actions such as lifting, lowering, and stopping. During the no-load trial pulling process, pay attention to observing the operation of the chain hoist, including whether the transmission of the chain is smooth, whether the braking effect of the brake is good, and whether the operation of the handle is flexible. If any abnormal situation is found, the trial pulling should be stopped immediately, and inspection and maintenance should be carried out.

　　(2) Load test pull

　　After the no-load test is normal, perform a load test. Gradually increase the load weight, starting from a smaller weight and gradually increasing to the rated load of the stage chain hoist. During the load test, pay attention to observing the operation of the chain hoist, including the load-bearing capacity of the chain, the braking effect of the brake, and the stability of the equipment. At the same time, use force gauges and other tools to measure the lifting and lowering forces of the chain hoist under different loads to ensure that its performance meets the requirements.

　　(3) Safety device testing

　　During the load test, it is also necessary to test the safety device of the stage chain hoist. For example, testing whether the overload protection device can automatically cut off the power supply when the load exceeds the rated load; Test whether the limit protection device can automatically stop running when the chain rises or falls to the limit position. Ensure that safety devices are functioning properly and can be activated promptly in emergency situations.

　　2、 The importance of trial pulling is reflected

　　(1) Ensure stage safety

　　Stage performances usually involve a large number of personnel and equipment, and safety is crucial. Trial pulling can ensure the safety of stage chain hoists under load conditions, avoid accidents caused by equipment failures, and safeguard the lives and property of stage personnel and audience.

　　(2) Improve the quality of performances

　　The stable operation of the stage hoist is crucial for presenting the stage effect. By trial pulling, potential issues with the equipment can be identified and resolved in advance, ensuring smooth operation during the performance and improving the quality and effectiveness of the show.

　　(3) Extend equipment lifespan

　　Trial pulling can test the load capacity and operational performance of the stage chain hoist, avoiding the equipment from working under overload or poor operating conditions, thereby extending the service life of the equipment. At the same time, trial pulling can also provide reference for equipment maintenance and upkeep, ensuring that the equipment is always in good condition.

　　(4) Compliant with regulatory requirements

　　In some countries and regions, the use of stage equipment needs to comply with relevant regulations and standards. Trial pulling is an important step in ensuring that stage chain hoists comply with regulatory requirements and provide legal and safe equipment support for stage performances.
