Mainly used in multi-purpose room, indoor and outdoor stadiums, television studios, schools gyms, classrooms, multi-function use of indoor or outdoor hall.
Telescopic tribunes is made of following parts and system:
1. Equal-height platform (with casters).
2. Guardrail.
3. Expansion drive (manual drive/power drive).
4. Front-mounted seat; Rear-mounted seat (flip by hand or electric).
5. Control system.
6. Other auxiliary devices (Row of the display device, the obstacles stop device, limiting device).
What kind of steel that telescopic tribunes use? What is the grades of the steel?
The beams, columns of the telescopic tribunes using cold-formed steel; Other components like crosspiece, bottom wheel beam and railings are using high frequency welded pipe (well tube, rectangular tube, pipe, etc)
The material quality is “Q235A”, equal to old standard A3 steel. “Q” means Yield strength. “235” means the yield strength of the steel is 235MP, A level steel. Belong to ordinary carbon steels.

What kind of wheels the telescopic tribunes use? What is the loading capacity?
The wheels are made of iron that covered with polyurethane layer, diameter Ø100mm; named “4 inch thick double bearing polyurethane wheel”. Loading capacity is 250KG/each one. The polyurethane layer of the wheels have slight flexible when it under pressure.
The picture is the 4 inch wheels.
What kind of panel the telescopic tribunes use?
A requirements of grandstand panel materials: divided into two type of indoor and outdoor. Usually, it depends on customer request. General indoor material is 18mm medium density melamine board. Or 18mm composite board that covered with rubber leather or carpet; Or 18mm composite board that covered with fireproofing board or fire prevention fillet. Although the melamine already have fire prevention composition, the multiply plywood still need to spray fire coatings.
Generally, the materials of step panel of outdoor stands are 2mm riffled plate or 18mm bamboo veneer.
If you choose the riffled plate as the step panel, you need to do periodic service (periodic anti-corrosion maintenance service); If you choose bamboo veneer as step panel, you need to cover it with rubber leather or carpet, but you can choose not.

How to deal with the step edge of the telescopic tribunes?
The step edge of the telescopic tribunes is cladding with special production of striped of aluminum alloy article decoration. After the bronze surface oxidation process, the corner will sealed with plastic cover, looks not only beautiful but very safe!
What kind of electric drive way the telescopic tribunes use?
There are two ways, friction wheel drive device(front drive) and folded chain drive device(after drive). But usually use the friction wheel drive.
The friction wheel drives use the motor through a sprocket chain drive high-intensity axis. High-strength shaft driven friction wheel rotated by the motor rotating to drive stands for the retractable running. Because this device is installed in the front row of the stand(first row)step, so it is called front drive device.
Which form of electric drive the telescopic tribunes use?
In generally, the electric control system of telescopic tribunes will adopt trip switch, AC contactor, the pros and cons of the switch button(manual control box, infrared remote control, a touch screen) mode. The system using limit position stop mode, it means, when you press the button, the stand will keep running to the limited position, then stop. For half-way stop, you must press the stop button. The system is equipped with a thermal relay, have reload protection of itself. Besides, according to the customer request, can add P sound device, digital row number display device etc.

What method have been taken of steel anticorrosive processing?
(1) When the steel structure is shaped up, after the surface polished, surface degreasing, rust clean, spray anti-rust paint once and finish twice, the surface color is greenish-blue and black, or the customer specified(optional) color.
(2) Spraying plastic
What is the difference between the front-drive seat and the after-drive seat?
(1) The front seat is installed at the front of the steps of the grandstand. The height of the steps of the grandstand and the height of the seat piece form a sitting height of the seat, which is in the form of a fixed seat piece and a foldable back. Therefore, the steps are too low and the double-row stands on the first floor cannot be equipped with front-mounted seats. The front-mounted seats can only be flipped manually without electric flipping. The front-mounted seats can only be installed on the stands of the single-row seats on each floor.

(2) The rear seat is installed behind the steps of the grandstand, and can be folded for a single seat. A row of overturned seats is equipped with a flip device box seat in the lower part, and a tension spring is installed in the box seat to offset most of the weight of the seat. Resistance torque, reducing the power to flip the seat. The number of overturned rear seats is generally 6-12 in a row. The rear-mounted seats can be turned electrically, but only if the seat and backrest of the seat can be automatically folded under the action of gravity or torsion springs. The number of seats that can be flipped per motor is similar to the number of seats that can be flipped manually, 6-12 seats. No matter what type of stand, as long as the floor height is suitable, rear-mounted seats can be installed.

If you are going to put the telescopic tribunes on the floor directly, we request the material of the floor must be very compact wood, like beech or xylosma etc. If the floor is supported by wooden keel, you should adopt strengthen measures at the areas which the wheels will passed. If the telescopic tribunes is placed in the floor surface, then the floor need have enough loading capacity.
What are the important design parameters of telescopic tribunes?
Basically has the following points:
1. Loading capacity of stand panel: 300kg/m².
2. Storey height: 240-320mm, based on seat type and customer request.
3. Width of foot step: 750-1000mm, based on seat type and customer request.
4. Stand walking speed: 5m/min.
5. Power: 380V or 220V, depends on the actual situation.
6. Motor power: According to the actual situation.
