Technical Parameters Of Barrier Gate

      Priority is given to distinguishing between the purchase of barrier gates: straight pole barrier gates, fence barrier gates, and advertising barrier gates. The focus of parameters varies in different scenarios, such as parking lots, park gates, and construction site entrances and exits. The required parameters are classified into major categories and can be directly used as a comparison table.

Movement and power (core, determining lifespan and failure rate)
      1, Drive mode: DC brushless motor (preferred): gentle start stop, low noise, adjustable speed, long lifespan, stable rebound when encountering resistance; AC motor: Low cost, high impact, high noise, suitable for low-frequency use. Key focus: motor power, conventional 30120W; power is not necessarily better, brushless 60W is sufficient for most scenarios.
      2. Landing time (opening time) for high-speed barriers: 0.6-1.0s → for high-speed license plate recognition parking lots with high and medium traffic flow, for high-speed barriers: 1.5-3s → for regular entrances and exits in residential areas and parks, for slow barriers: 3-6s → for heavy-duty fences/advertising barriers at factories and gates. Attention: the longer the pole, the faster it cannot be selected, as it may shake or break the pole. It is recommended to use a 34 meter straight pole for at least 1.5 seconds.
      3. Maximum adaptive pole length for straight poles: 1-6 meters; Fences/advertising barriers are generally 2-4 meters long. It is strictly prohibited to exceed the specifications of the rod, for example, if the machine has a nominal maximum of 4 meters and a hard rod of 6 meters is installed, it will frequently damage the movement. 4. The rebound function must have: pressure sensing/infrared resistance. Vehicles and people touching the brake lever will automatically lift the lever to prevent smashing vehicles and people; The brushless movement supports electronic resistance and is more reliable than pure spring mechanical type. 5. The spring configuration balances the number of springs, with longer rods having more springs; Poor quality barrier gate springs are prone to fatigue and fracture, causing the rod to fall off.

Electrical and Control Parameters
      1. Prioritize AC 220V mains power for working voltage; Partial brushless control board DC24V. Confirm that the control board supports external license plate recognition and ground sensing coils.
      2. The interface capability (very important) must have interfaces: ground sensing coil interface (vehicle detector, automatic gate closing when passing) dry contact switch signal (connected to license plate recognition, access control, PLC) relay output, fire linkage interface (forced opening of fire signal, essential for fire protection acceptance in the park/construction site) RS485/relay, whether it supports platform docking.
      3. Working environment working temperature: -30 ℃~+65 ℃, outdoor must have a wide temperature range; Protection level: chassis IP54 or above, for outdoor use, resistant to rainwater and dust; IP65 is better.
      4. Continuous working ability and continuous opening times: nominal ≥ 5 million times for the movement, and recommended 10 million times for high-frequency train yards; Three million visits to low-frequency residential areas are sufficient. Don't choose cheap household models with high traffic volume.
Gate pole parameter pole type:

      straight pole, two/three bar fence, advertising barrier gate. Rod material: Aluminum alloy preferred; Iron fences are prone to rusting. Rod weight: The movement should match the rod weight, and the heavier the weight, the greater the load on the movement. Rubber strip anti-collision strip: The bottom of the straight rod is equipped with a soft rubber strip to reduce damage caused by smashing the vehicle.

Safety function parameters (must be checked for acceptance) Ground sensing vehicle detector: anti smashing brake, do not drop the pole before the vehicle leaves; Separate single path and dual path ground feel. Infrared radiation: auxiliary anti smashing, providing a cover when the ground feel is poor. Manual clutch device: In the event of a power outage, manually lift the lever by hand, which is essential for emergency situations and cannot be purchased without it. The anti detachment and anti fall mechanism of the gate rod prevents the spring from breaking and directly falling off the rod, causing injury.

Chassis and structural chassis thickness:

      Cold rolled steel plate ≥ 1.2mm; thin iron sheet is prone to deformation. Surface spray coating, outdoor anti-corrosion and rust prevention. The size of the chassis, whether the installation space is sufficient, and whether it supports left/right interchangeability (the machine can be installed on both sides without the need to separate the left and right switches for stocking).

Additional functional parameters (optional) include counting and passing LED display screens; Voice broadcasting; Number of remote controls, supporting Bluetooth and 4G remote control; The flipping angle and power consumption of the advertising barrier flap.

Summary of key procurement points in different scenarios:

1. Commercial parking lots with high traffic flow: DC brushless, 1-1.5s takeoff and landing, ground sensing detector, with a lifespan of over 5 million times, rebound when encountering obstacles, and support for license plate recognition dry contacts.

2. Key points of entrance and exit (fence gate) in the residential area: adaptation to fence pole length, fire linkage interface, manual clutch IP54, Anti fall mechanism.

3. Key points of the construction site factory gate: thickness of the chassis steel plate, wide temperature range, mandatory opening for fire protection, durable movement, do not pursue too fast speed.

4. Key points of advertising barrier gate: motor load, flipping mechanism, power consumption, wind resistance level, careful selection in strong wind environment.

Don't just look at the appearance and price to avoid pitfalls, ask clearly whether it is brushless or AC motor; Many low-priced targets are actually for communication. Check the parameters: maximum pole length, do not exceed the pole configuration. Confirmation: The manual disconnection and fire linkage interface for power outage have been cut off by many low-priced machines, and the acceptance cannot be passed. Ask about the warranty of accessories: the warranty period of the movement, and the vulnerable parts of the spring and controller.
