There is no doubt that the three roll gate is the channel gate with the widest range of use, the most uses and the most types in China. When defining the types of three roll gates, we often classify the three roll gates according to the following principles:

1: According to the braking mode, the three roller brake can be divided into: full-automatic braking three roller brake and semi-automatic braking three roller brake. This type belongs to the type of high-grade brake. With the continuous improvement of people's living standards, the mainstream brake abroad has gradually begun to make great development in China;

2: According to the traffic mode, the three roller brake can be divided into: fully automatic three roller brake, semi-automatic three roller brake and mechanical electric three roller brake;

3: According to the traffic mode, the three roller brake can be divided into: electric three roller brake and manual three roller brake;

4: According to the traffic direction, the three roller gate can be divided into: one-way three roller gate and two-way three roller gate;

5: According to the gate machine style, the three roll gate can be divided into: bridge three roll gate and vertical three roll gate;

6: According to the flow, the three roller gate can be divided into: ordinary three roller gate, high flow three roller gate;

At present, the mainstream three roller gates in China are classified as fully automatic three roller gates, semi-automatic three roller gates and manual three roller gates

Fully automatic three roller brake: also known as electric three roller brake, it is equipped with a motor. All the operation of the gate is driven by the motor. At the same time, the motor drives the brake rod to rotate during power on, so as to realize automatic power on, which is very convenient to use

Semi automatic three roller brake: one motor or two electromagnets are configured to control the locking and unlocking of the incoming and outgoing directions. After the passage is authorized, the electromagnet drives the unlocking arm to unlock. The release brake rod can rotate in one direction, and the user can gently push the brake rod through the channel. The semi-automatic three roller brake is designed with anti reverse function, which can effectively prevent pedestrians from retrograde

Manual three roller brake: pure machinery is not equipped with any electrical equipment. Users can pass through the channel by gently pushing the brake rod without swiping the card. The automatic positioning and reset system can control the free passage in one direction, and the other direction is locked and prohibited.
