The wonderful performance of stage chain hoist in the process of truss lifting

　　1、 The importance of stage chain hoists and trusses

　　As an important supporting part of the stage structure, the stage truss undertakes important tasks such as hanging lighting, sound equipment, and scenery. The stage hoist is a key tool for lifting these devices and props. Their synergistic effect has laid a solid foundation for the wonderful presentation on stage.

　　2、 Preparation before lifting

　　(1) Check the equipment

　　Before lifting the truss, a comprehensive inspection of the stage hoist and truss must be carried out. Check whether the chain of the chain hoist is intact, whether the hook is firm, and whether the brake is sensitive and reliable. At the same time, check whether the structure of the truss is stable and whether the connection parts are firm.

　　(2) Determine the lifting plan

　　Develop a reasonable lifting plan based on factors such as the weight, size, and lifting height of stage equipment and props. Determine the quantity, position, and lifting sequence of the chain hoist to ensure the safety and stability of the lifting process.

　　(3) Safety protection measures

　　Set up necessary safety protection measures at the lifting site, such as warning lines, warning signs, etc. Equip operators with necessary personal protective equipment, such as safety helmets, seat belts, etc.

　　3、 Key operating points during lifting process

　　(1) Correctly install the chain hoist

　　Install the stage chain hoist correctly on the truss, ensuring that the hook is securely connected to the lifting object. According to the lifting plan, adjust the position and angle of the chain hoist to ensure a smooth and safe lifting process.

　　(2) Slowly pull the chain

　　The operator slowly pulls the chain of the stage hoist to gradually raise the lifting object. During the process of pulling the chain, it is important to maintain a constant speed and stability, and avoid sudden acceleration or deceleration to prevent the lifting object from shaking.

　　(3) Closely observe the lifting process

　　During the lifting process, the operator should closely observe the operation of the stage hoist and truss. Pay attention to the tightness of the chain, the firmness of the hook, and the stability of the truss. If any abnormal situation is found, the lifting operation should be stopped immediately and corresponding measures should be taken for handling.

　　(4) Control the lifting height

　　According to the lifting plan, control the lifting height of the stage chain hoist. During the lifting process, always pay attention to the distance between the lifted object and surrounding objects to avoid collisions. At the same time, it is important to ensure that the lifting object remains level during the lifting process and avoid tilting.

　　4、 Precautions after lifting

　　(1) Fixed lifting objects

　　After the lifting object reaches the designated position, ropes or other fixing devices should be used in a timely manner to fix the lifting object on the truss, ensuring its stability and reliability.

　　(2) Check the equipment status

　　After the lifting is completed, the stage hoist and truss should be inspected again. Check if the chain, hook, and brake of the chain hoist are damaged, and if the structure of the truss is stable. If there is a problem, it should be repaired or replaced in a timely manner.

　　(3) Clean up the site

　　Clean up the lifting site and store the stage hoist and other tools and equipment properly. Keep the site clean and safe, and prepare for the next lifting operation.
