Precautions for the construction of stage electric hoist truss

　　The combination of stage electric hoists and trusses can provide efficient and stable support and lifting solutions for stage construction in stage performances and events. However, in order to ensure the safety and smooth progress of the construction process, the following are some precautions to be taken in the construction of stage electric hoist trusses.

　　1、 Planning and Design Phase

　　(1) Load calculation

　　Accurate load calculations must be performed before selecting trusses and stage electric hoists. Considering the weight of various equipment, props, and personnel on stage, ensure that the load-bearing capacity of the truss and electric hoist can meet actual needs.

　　Consult professional engineers or calculate loads according to relevant standards and specifications to avoid overloading situations.

　　(2) Design rationality

　　The design of the stage truss should comply with the stage layout and performance requirements. Ensure that the height, span, and shape of the truss can meet the installation requirements of lighting, sound, and other equipment, while providing sufficient space for actors and staff.

　　Considering the installation location and operating trajectory of the electric hoist, design a reasonable truss structure to facilitate the operation and maintenance of the electric hoist.

　　2、 Material selection and inspection

　　(1) Truss material

　　Choose truss materials with reliable quality and high strength. Common truss materials include aluminum alloy and steel. Choose the appropriate material according to actual needs. Aluminum alloy trusses have the advantages of being lightweight and corrosion-resistant, making them suitable for building small stages; Steel trusses are more sturdy and durable, suitable for large stages and heavy loads.

　　Check the quality certificate and inspection report of the truss material to ensure that it meets the relevant standards.

　　(2) Selection of electric hoist

　　Choose an electric hoist suitable for stage use. Considering the particularity of the stage environment, electric hoists should have waterproof, dustproof, corrosion-resistant and other properties. Meanwhile, select the appropriate lifting speed and height according to the load requirements.

　　Check the quality certification and safety markings of the electric hoist to ensure that it meets national safety standards.
