The versatile manual electric retractable stand relies on thick galvanized square steel girders for the overall framework. The surface electrostatic injection process improves corrosion resistance, which is not easily rusted and deformed during long-term indoor and outdoor use, the standing steps use anti-slip sheet steel, which has excellent pressure resistance and anti-slip performance, and the seats use new HDPE high-density polyethylene integrated injection molding. Raw materials are reinforced with anti-ultraviolet additives, which are not easily bleached and cracked in outdoor environments, the transmission part is equipped with wear-resistant gears and stainless steel hardware accessories, and the operation is smooth and not easier to suffer from craton damage. The product has two modes of operation: electric one-button stretching, manual push and pull catching, and the catching occupies very little space. It can quickly release the complete venue for various activities such as ball games, art shows, group gatherings and so on. The layout of multiple staircases is designed to ensure that the view of the spectators is sheltered, and the overall structure has been stressed with weight, and a large number of people sit and lean together without forming a distortion or curve. The stands are equipped with security guardrails, anti-ski aisles and standardized evacuation channels, which fully comply with the fire inspection code, the seat color, number of rows and height can be customized on demand, and the scale and opening speed are fast, which can efficiently complete the venue switching to meet the rapid layout requirements of various activities. The entire stands, from steel cutting, full welding, and injection molding to the assembly of the seats, are manually and intricately operated by senior technicians. All the welding is smooth and free from sharp scratches. The workers repeatedly debug the retractable tracks and perform full load testing before the finished product leaves the factory. Check the strength of screws, guardrails, and seats every step of the way, all products that are defective are filtered out, and strictly control the quality of the factory. This stands are widely used in indoor basketball halls and badminton courts in primary and secondary schools and colleges, in service of school sports games, school opening ceremonies, Activities such as arts and crafts galas are also adapted to community cultural and sports centers, multifunctional report halls, small performance halls, indoor comprehensive sports venues, swimming halls, and temporary event venues built by enterprises, which can flexibly expand the audience seats. The indoor sports hall of Hangjia 2 Middle School is a typical implementation case of this product. The venue uses multi-level escalator retractable stands with two yellow and green foam seats, and high-strength load bearing structure is suitable for the high density of people on the campus. After the stands are folded, the venue can carry out physical education training normally, and greatly improve the comprehensive utilization rate of the venue. After the project is delivered, it is successfully approved by the university. The stands are stable in structure, stretched and operated smoothly, fully matching the daily needs of the campus's cultural and sports activities. Shengrun Sports implements tens of thousands of standing project projects each year, and welcomes engineering purchasers from all over the country to visit the project site to verify the comprehensive quality of the products.
