Three roller brake product principle and function

Regarding the pedestrian access management system, many people know their uses but do not know the actual role. For example: three-roll gates, also known as three-slug gates, three-roll gates are suitable for all types of public places requiring pedestrian traffic. Such as scenic spots, exhibition halls, movie theaters, docks, train stations, bus stations, etc. where tickets need to be checked; factory attendance, dining hall consumption, golf courses, and monthly card recreation centers must be authorized to enter; electronics factory anti-static control area, Need to identify faces, fingerprints and other security measures tight units. The reason for choosing a three roller gate is as follows:


One, three roller gate features:

1. Aluminum alloy or stainless steel all weatherproof box body, compared with the wing gate swing gate and other walkway equipment, three roller gate is more affordable.

2, with a personalized installation interface (such as card readers, light installation, etc.), to ensure that the system integrator control gate device installation is simple and convenient.

3. The movement of the triple stick switch gate is automatically adjusted to the hydraulic shock absorber. When using the three stick brake operation, the sound is very small, no impact, and the brake lever is automatically decelerated back to the middle. The movement surface is electroplated with yellow dichromate.

4. Can be programmed with gate control, one or two directions (set by the user).

5. The base is fixed with expansion bolts.

Second, the three roller gate movement 1, mechanical gate movement refers to the use of gates in the lifting of the control after the release of the three-pronged manpower push rod release; release after the other rod through the movement of the hydraulic damping device stays in the horizontal position , need to be released again after the release of control. The putter only needs 0.5Kg of thrust.

2. The motor core is equipped with a motor in the gate. After the gate is released from control, the trigeminal rod will move forward by an angle. When the pedestrian touches the trigeminal again, the motor will take the initiative to turn the rod until another rod returns. Complete the release action after reaching the horizontal position.

Three, three roller gate product advantages:

1. The cost of the triple roller gate (three roller gate) is lower than that of other types of gates. It can be customized according to different functional requirements, with priority given to the customer's purchase intention;

2. The three-roll gate has a more practical anti-trailing function. Compared with other gates, the design of the triple roller gate has already focused on the anti-trailer design, and no additional auxiliary components are required.

3. The design of the triple roller gate is relatively easy to guide the user's application. Because of its high popularity and simple structure, ordinary first-time users do not need to learn and can be applied directly.
