Precautions for stage chain hoist in truss construction II

　　In the field of stage construction, truss structures are widely used due to their stability and flexibility. As an important lifting tool, the stage chain hoist plays a crucial role in the process of truss construction. However, in order to ensure the safety and smooth progress of the construction process, there are some precautions that need to be kept in mind.

　　3、 The correct use of stage chain hoist

　　(1) Installation and fixation

　　Install and secure the stage chain hoist according to the correct method. Ensure that the connection between the hook and the truss is firm and reliable, and that the chain is not twisted or tangled.

　　According to the instructions for using the chain hoist, choose the appropriate installation position and fixing method. Hand pulled hoists can be fixed to trusses or other sturdy structures using lifting rings, bolts, and other connecting components.

　　(2) Operating standards

　　Strictly follow the operating procedures when operating the stage hoist. When pulling the zipper tape, apply even force to avoid sudden or forceful pulling or releasing.

　　Pay attention to the operation of the chain hoist. If any abnormal situations such as chain jamming or loose hooks are found, stop the operation immediately, check the cause, and take appropriate measures.

　　When lifting the truss, ensure that the lifting speed of each chain hoist is consistent to avoid tilting or twisting the truss due to different speeds.

　　(3) Security protection

　　When using stage chain hoists, it is necessary to wear necessary safety protective equipment such as helmets, seat belts, etc.

　　During the construction process, warning signs should be set up to prohibit unrelated personnel from entering the construction area. At the same time, assign a dedicated person to be responsible for on-site safety supervision to ensure the safety of the construction process.

　　4、 Inspection and maintenance after construction

　　(1) Check the truss structure

　　After the completion of the truss construction, conduct a comprehensive inspection of the structure of the truss. Check whether each connection point is firm and whether the overall stability of the truss is good.

　　Use tools such as a spirit level to check the levelness and verticality of the truss, ensuring that the installation of the truss meets the design requirements.

　　(2) Maintain the stage chain hoist

　　Clean and maintain the used stage hoist. Remove dust and debris from components such as chains and hooks, apply rust proof oil to extend the service life of the chain hoist.

　　Check whether the various components of the chain hoist are damaged or worn, and replace them in a timely manner if necessary. Store the chain hoist in a dry and ventilated place to avoid moisture and corrosion.

　　In short, during the construction of the stage chain hoist truss, it is necessary to choose a suitable chain hoist, prepare well before construction, use the chain hoist correctly, and conduct inspection and maintenance after construction. Only in this way can the safety and smooth construction of the truss be ensured, providing a stable and reliable support structure for stage performances.
