Our most affordable semi-automatic three-roller gate is an upgraded product of the manual three-roller gate. The mechanism is equipped with two electromagnets to control the in and out direction locking and unlocking. After the passage is authorized, the movement positioning arm is opened, the hand pushes the brake lever to turn 120°, the electromagnet drives the unlocking arm to unlock, the release lever can be rotated in one direction, and the user can gently push the brake lever to pass through the passage.
When the authorization is not passed, the authorization of illegal entry will be cancelled within the specified time, the gate bar will block the passage, and the power will automatically drop the rod, which can effectively prevent pedestrians from retrograde.
