The structural form of the door is: download heavy, upper oriented (or upper load bearing, lower oriented), the door is on two or more tracks, each door is divided into multiple doors, each door moves to both sides of the door. The main components of the gate: steel structure, upper guide, lower track, transmission device, anti-collision device, etc., the general service life is 50 years. The frame of the door body adopts the steel structure. According to the requirements of the national load code, the steel structure of the door body is calculated and strengthened to ensure the strength and steel of the door body. The deflection of the gate frame under the ultimate wind pressure is ≤L\450(L is the height of the gate), which can withstand the wind load once in 50 years, and the structure grade is Ⅲ. The frame is welded into a steel frame using section steel. Door open a small door for pedestrian passage, easy to use at ordinary times. The door has both electric and manual functions.

Technical parameters:

1. Drive motor power: 0.375KW-5.5kW, working voltage (V)/ frequency (HZ)

2. Opening speed: 5-20m\min can be single speed or dual speed

3. Basic wind pressure: The door can be opened and closed normally when the wind speed is 24 m/s

4. Control system: combination of centralized control, remote control and separate door control

5. Sound insulation performance: greater than 40dB

6. Heat transfer coefficient U:2W\m2.k

7. Ambient temperature (℃)-40-+70

8. Seismic high intensity 8 degrees (or according to the user area)

According to customer requirements, it can be made into radiation-proof, thermal insulation (low temperature cold storage, high temperature oven, normal temperature), soundproof, explosion-proof, anti-nuclear radiation and other push-pull doors, which are widely used in airports, shipyards and other places, as well as factories, workshops and warehouses in heavy industry, military industry, cold storage and other fields.
