In the global market of multi-functional stadiums, gymnasiums, schools, swimming pools and convention centers, Low-back Telescopic Grandstand has become the preferred seating system due to its excellent sightline, high space utilization, cost-efficiency and strong environmental adaptability. However, for most buyers, especially overseas customers, distributors and engineering contractors, the real difficulty is not just purchasing a single product, but a complete, reliable, one-stop turnkey solution that can be truly implemented on site with minimal risk, short construction period and stable operation.
The Low-back Telescopic Grandstand is a modular stadium seating system that integrates efficient space utilization, safety and stability, comfort and durability, and intelligent convenience. Its core features a retractable mechanical structure and low-back seat design, enabling rapid space transformation in venues for events, performances, conferences, training, and other scenarios. It is widely applicable to stadiums, school auditoriums, multi-functional halls, community cultural and sports centers, exhibition venues, and other similar spaces.
Traditional fixed stands suffer from problems such as low space utilization, limited functionality, and difficulty in renovation: fixed seats occupy a large amount of space and cannot meet the venue's "multi-purpose" needs; high-backed seats obstruct the view of those behind, and seating density is low; old stands have aging structures, high maintenance costs, and prominent safety hazards. Temporary seats, on the other hand, are cumbersome to install, have poor stability, insufficient comfort, and low reuse rates, making them unsuitable for high-frequency, high-standard venue usage scenarios. Low-back retractable grandstands, as a new generation of stadium seating solutions, completely solve the pain points of traditional grandstands. Their main advantages are as follows:
Extreme Space Optimization:When retracted, the footprint is only 15%-20% of the unfolded state, freeing up over 80% of the venue space and achieving "multi-purpose use";
Efficient Scene Transition:The electric version can be retracted in just 1-2 minutes with a single button press, while the manual version can be switched in 3-5 minutes, adapting to multiple events and types of activities;
Balance of Visibility and Seating Density:The low-back design ensures both long-term comfort and maximizes rear-seat visibility, increasing seating density by 12%-15% compared to traditional grandstands;
Safe, Durable, and Reliable:Meets national sports stadium safety standards, with a main structure lifespan of over 15 years and seats that have withstood over 200,000 fatigue tests without deformation;
Strong Customization and Adaptability:The modular design supports full-dimensional customization of size, color, function, and layout, adapting to regular and irregular venues, indoor and outdoor scenarios.
The low-back telescopic grandstand adopts a modular, layered telescopic structure, consisting of five core modules: a support frame system, a telescopic transmission system, a seat unit system, a safety protection system, and an intelligent control system. The overall structure features a "stepped telescopic and drawer-style storage" design, ensuring smooth operation, even force distribution, and compact storage. The supporting frame system adopts Q235 national standard high-strength carbon structural steel, with a main frame steel plate thickness of 3mm. The load-bearing beams use 190×60×30×2.5mm special-shaped steel pipes, with a double reinforcement process of welding and riveting. The welds are tested by ultrasonic flaw detection and are free of cracks, porosity, and slag inclusions. The rated live load is 500kg/㎡, and the ultimate load is 750kg/㎡, which meets the needs of concentrated loads and instantaneous impact loads of a full-seat population. The rear-mounted cantilever support + front-mounted rail load-bearing dual structure eliminates the obstruction of the middle column and improves the utilization rate of the bottom space. The entire frame is treated with shot blasting and electrostatic powder coating with a coating thickness of 60-80μm, which is rust-proof, corrosion-proof, and UV-proof, and can adapt to extreme indoor and outdoor environments ranging from -60℃ to +80℃.
Low-back telescopic grandstands are available in three main types: electric telescopic, manual telescopic, and a combination of both, catering to different usage frequencies and budget requirements:
Electric Telescopic System: The drive unit uses a synchronous geared motor with a power of 0.75-1.5kw and selectable voltage (380V/220V). It features overload protection, overheat protection, and power-off self-locking. The transmission structure uses a high-precision gear rack and chain drive, coupled with double-row deep groove ball bearings, achieving a transmission efficiency of ≥95% and operating noise of ≤50 decibels. The synchronization mechanism, through a combination of sliding rails, double guide wheels, and lateral adjustment wheels, eliminates deviation problems caused by manufacturing, installation, and ground errors, achieving a long-distance running stability rate of 99.8%.
Manual Telescopic System: Utilizes a hand crank and mechanical self-locking transmission, requiring no power supply and requiring minimal effort (can be operated by a single person). Suitable for small to medium-sized venues with low usage frequency (≤2 times per week) and limited budgets. It automatically locks after reaching the extended/retracted position, preventing slippage and loosening, ensuring a high safety factor. 100%; Dual-use system: electric as the primary mode and manual as the secondary mode. It can switch to manual mode during power outages to ensure normal use in extreme scenarios and is suitable for large venues and important event locations.
