Safety and Reliability for Sectional industrial Door

Balance system for commercial doors

The balance system is characterized by safety, stability, and compact construction. The large torsion spring undergoes an oil-tempering process, allowing for an operating cycle of more than 100,000 times.
When the steel torsion spring breaks, the device immediately locks the torsion spring shaft, placing the door in a secure state.
When the steel cable breaks, the device clamps onto the track to prevent the door from continuing to fall.
The door panel anti-pinch protection benefits from a specially designed door panel structure, which ensures that there is no risk of fingers getting caught in the door panel at any position or angle.
The rollers run with precise positioning in specially designed sliding track profiles, ensuring that the door panel does not derail or fall when turning or in a horizontal position.

Photoelectric Protection

By protecting the photocell before the door comes into contact with an obstacle, it can detect the presence of obstacles, and the gate immediately stops its downward movement, preventing accidents from occurring.

Safety Airbag

During the closing process of the door, this device continuously monitors whether there are obstacles underneath the door. Once it encounters an obstacle, under the action of this device, it immediately changes direction to open, avoiding accidents.

Bottom Seal

The sealing rubber installed at the bottom of the door panel serves the dual function of sealing and buffering. The O-shaped rubber bottom edge provides effective cushioning when the door is closed, while also maintaining continuous pressure between the door panel and the ground, ensuring optimal sealing between the door panel and the ground.

Top Seal

The sealing rubber installed at the upper end of the door panel ensures excellent sealing between the top of the door and the wall. The highly elastic top sealing rubber maintains continuous pressure against the wall, thereby achieving optimal sealing effectiveness.

Side Seal

The side seal is a sealing rubber installed on the side of the track, which can seal the gap between the door and the wall. The elastic rubber seal ensures a continuous and tight seal between the door panel and the wall, thereby ensuring optimal sealing effectiveness of the door.

Anti-Intrusion Side Guard Panels

The semi-enclosed track prevents hands and foreign objects from entering the track area from the side, thus avoiding accidental injuries.

Built-In Steel Wire Rope

The steel wire rope of the gate is concealed between the track and the door panel, preventing it from getting entangled with other objects and avoiding potential hazards.
