Electric manual fixed telescopic grandstand, venue grandstand

Description :

　　Railing: The railing is made of steel material (matte), and the front and side railings are fixed, which means that the movable grandstand does not need to be inserted or removed during the expansion and contraction process, and is connected as a whole. The top of the guardrail can withstand a horizontal force of 65kg/m; The middle of the guardrail is 135kg/m.

　　Blow molded by molds, it has beautiful, comfortable, durable, easy to install, maintain and manage

　　Stand strength: Stand frame strength: Static load per seat ≥ 200kg; Bed frame impact resistance strength: Static load per seat ≥ 200kg. Load in the middle of each layer ≥ 80kg, and impact at a height of 300mm will not deform. a、 Seat and step load capacity: 172N/m b, uniformly distributed total load capacity: not less than 4785N/m 2c in the horizontal direction, parallel swing load: 350N/m d per row, vertical swing load: 146N/m per row. Under the action of dynamic loads, the overall structure is stable and the bearing surface does not deform.

　　Spray coating: All metal components that make up the telescopic grandstand are pickled. Afterwards, phosphating treatment is carried out at a temperature of 60 degrees to ensure that the surface has anti-corrosion protection. One spraying procedure is to oxidize and spray the powder coating through electrostatic action, which is carried out at 190 degrees for about 20 minutes. The color is unique to our company's production and cannot be changed. All screws and nuts are national standard parts.

　　Motor: The motor automatically retracts and drives the shaft through a series of transmission mechanisms, including support, specially made rubber unmarked wheels, control panel, surface button belts, and a mobile alarm system using lights and buzzers. All motors in each section are equipped with independent modules for expansion and contraction, equipped with special codes to ensure parallelism between modules, and each code is controlled by a computer system.

　　Drive mechanism: adopts electric control type, with wired manual control function. Adopting imported three-phase reduction motors with a power of 550-1100W (according to the stand design) and a voltage of 380V, it has the characteristics of large reduction ratio, high efficiency, low noise, and few faults. And it adopts a front mounted four-wheel chain drive system, which consists of driving cast iron wheels, motor mounting bracket, motor transmission rod, and motor. The electric motor is directly connected to the driving wheel through a transmission rod, which can exert the transmission effect of the motor and provide strong power for the stands; The four-wheel drive system remains stable and does not experience any deviation even when installed on uneven ground. Drive cast iron wheel: outer diameter 170mm, wheel width 100mm, made of ductile iron, with high strength, toughness, and wear resistance. The outer layer is wrapped with 15mm thick wear-resistant polyurethane, with a hardness of 90-93A on the Shore scale. While the hardness meets the requirements for use, it provides limited protection for the ground from damage.
