Structural Features of Telescopic Grandstand
1. Steel frame support structure
The standardized support structure not only is beautiful, but also embodies its excellent mechanical properties to the greatest extent, and is safe and reliable.
① The vertical support column is welded and formed by high-strength cold-drawn steel pipe;
② The load-bearing beam is rolled and formed by high-strength steel plate, with high strength and high toughness;
(2. The steel frame structure of the telescopic grandstand)
③ The bottom walking wheel frame is made of cast iron and made of HT200. Polyurethane is applied externally, which is wear-resistant and avoids damage to the ground during walking. For high-end venues with wooden floors, it can effectively protect the surface of the wooden floor without causing damage to the wooden floor.
④ The aluminum alloy edging design is made of aluminum alloy, and the anti-skid rubber strip is embedded on it, which has good rigidity and light weight, and can prevent unnecessary accidents caused by slipping when the audience is walking.
⑤ The guide wheel is made of nylon 1010, which has good strength and low noise during work.
⑥ Connecting bolts adopt GB/T5783-1986 standard high-strength bolts, which are reliable in connection.
2. Modular design, convenient and quick installation, a gymnasium with thousands of people can be installed and put into use within a week.
3. The modern processing technology is adopted to ensure the perfect and accurate assembly combination between the components. All product accessories are laser cut, die stamping forming, mechanical manual assembly and welding.
4. The electrical control system of the grandstand is controlled by a microcomputer, the stroke of the telescopic grandstand is digitized, and the electric drive mode is used. There are manual control devices and remote control devices during operation.
5. The driving machinery can be either a polyurethane wheel type or a crawler type that can adapt to harsh environments. The driving device has the advantages of large reduction ratio, sufficient power, strong adaptability, high efficiency, low noise, few failures, long life, and no scratches on the floor.
6. All metal parts of the telescopic stand have been treated by pickling and degreasing, shot blasting and rust removal, electrostatic spraying and rust prevention.
