Full analysis of the manufacturing process of stage electric hoist

　　1、 Design and Planning

　　(1) Requirement analysis

　　The first step in manufacturing stage electric hoists is to conduct a demand analysis. Engineers will communicate with stage designers, performance teams, and equipment suppliers to understand the specific requirements of stage performances, including the required lifting weight, lifting height, operating speed, accuracy requirements, etc.

　　(2) Design proposal formulation

　　Based on the results of the requirements analysis, the design team will develop a detailed design plan. This plan includes the structural design of the electric hoist, motor selection, transmission system design, control system design, etc. In the design process, it is necessary to fully consider the special characteristics of the stage environment, such as space limitations, noise requirements, safety standards, etc.

　　2、 Material procurement and preparation

　　(1) Material selection

　　Stage electric hoists require the use of high-strength, corrosion-resistant, and wear-resistant materials to ensure their safety and reliability during long-term use. Common materials include high-quality steel, aluminum alloys, copper alloys, etc. At the same time, it is necessary to choose suitable components such as motors, reducers, brakes, and wire ropes.

　　(2) Material inspection

　　The purchased materials need to undergo strict inspection to ensure that their quality meets the design requirements. The inspection content includes the chemical composition, mechanical properties, dimensional accuracy, etc. of the material. For key components, non-destructive testing such as ultrasonic testing, magnetic particle testing, etc. is also required.

　　3、 Component processing

　　(1) Mechanical processing

　　According to the design drawings, various machine tools are used to process materials such as steel and aluminum alloy, and manufacture various components of the electric hoist, such as the shell, drum, gear, shaft, etc. During the processing, it is necessary to strictly control the dimensional accuracy and surface quality to ensure the assembly accuracy and performance of the components.

　　(2) Heat treatment

　　For some key components such as gears, shafts, etc., heat treatment is required to improve their hardness, strength, and wear resistance. Heat treatment processes include quenching, tempering, carburizing, etc.

　　(3) Surface treatment

　　In order to improve the corrosion resistance and aesthetics of the components, surface treatment is required. Common surface treatment methods include painting, galvanizing, chrome plating, etc.

　　4、 Assembly and Debugging

　　(1) Component assembly

　　Assemble the processed components to form a complete stage electric hoist. During the assembly process, it is necessary to strictly follow the assembly process requirements to ensure the accurate installation position and firm connection of each component.

　　(2) Electrical system installation

　　Install the electrical system of the electric hoist, including motors, controllers, sensors, cables, etc. The installation of electrical systems needs to comply with relevant electrical safety standards to ensure stable and reliable operation.

　　(3) Debugging and Testing

　　Debug and test the assembled stage electric hoist to ensure its performance meets the design requirements. The debugging content includes adjusting parameters such as motor speed, torque, and current, as well as testing the accuracy and stability of the transmission system. At the same time, safety performance tests such as overload protection, limit protection, emergency stop function, etc. need to be conducted.

　　5、 Quality Inspection and Packaging

　　(1) Quality inspection

　　Conduct comprehensive quality inspection on the manufactured stage electric hoist, including inspection of appearance quality, dimensional accuracy, performance indicators, safety performance, and other aspects. Quality inspection requires strict adherence to relevant standards and specifications to ensure that every electric hoist meets quality requirements.

　　(2) Packaging and Shipping

　　Stage electric hoists that have passed quality inspection need to be packaged to ensure that they are not damaged during transportation and storage. The packaging materials are usually wooden cases, foamed plastics, etc. The packaging method needs to be selected according to the size and weight of the electric hoist. After packaging is completed, the electric hoist will be shipped to the customer.
