The system will be stored in a cantilever manner. The system should be traced all the way to the end of the county arm and then expanded one by one from the first line.
Mobile
When it comes to convenient space usage, the system should be moved to another location and placed in different directions. And the system can also be used in the maximum space of a dedicated storage area

Telescopic bleacher detailed parameters
framework
(1) The overall frame of the telescopic bleacher is made of Q235A steel parts assembled by bolts. The yield strength, tensile strength and elongation of the steel must meet national standards.
(2) The grandstand is a vertical support structure. The density of the grandstand layer is 800mm, the density of the tail layer is 400mm; the height of the first layer is 330mm, and the height of other layers is 300mm. (The telescopic grandstand is a customized product, and the size can be slightly adjusted according to the actual site and customer needs.) The beam is installed through the upper and lower holes of the C-shaped beam, and the cantilever beam is installed at a distance of no more than 600mm. The cantilever beam adopts 50mm:*50mm*2.0m steel profile. In order to ensure the support performance of the grandstand frame for the pedal, the maximum center distance between the cantilever beams is s<600mm.
framework
(3) The retractable grandstand column adopts 10mm*560mm*2mm steel profile, and the bottom walking wheel is connected to the upper end support arm by welding. A connecting steel sheet with a thickness of not less than 6nn is welded on one side of the column support pipe and connected to the rear crossbeam of the grandstand. The rear crossbeam is a C-shaped 180mn*t5onmn..0mn
(4) The front end is connected to the front crossbeam, and the front crossbeam is made of 50m*2.0m carbon structural steel profile. A triangular support frame is added at the rear between every two columns to ensure that the grandstand will not swing when it is impacted horizontally. The triangular support frame is made of 40mn*20nn*2.0mn steel profile.
(5) Mechanical properties of the grandstand: The overall structure of the telescopic grandstand should have high and safe mechanical properties. The load-bearing capacity of the tabletop must meet the safety requirements of the audience sitting down, and it should have strong lateral stability after the audience sits down. The static load of the tabletop should be able to withstand a load of 6y/m? for 80 minutes, and there should be no obvious deformation or damage after unloading. After the grandstands are unfolded, based on the static load test, a static load of 360° horizontal tensile force is applied in the forward and lateral directions respectively for 5 minutes. The displacement of the grandstands is less than 1/200 of the length of the movable grandstands and the grandstands shall not tip over.
