Choosing the right boom barrier gate is not about finding the cheapest unit. It is about matching the motor duty cycle to your traffic volume, the arm length to your lane width, and the communication protocol to your access control system. This guide is written from a manufacturer's perspective — we build these gates in Shenzhen, China, and we know what fails in the field.
This is the first question we ask every customer. Measure the full opening width — not just the paved surface. The cabinet itself takes about 35cm.
| Lane Width | Recommended Boom Length | Gate Type |
|---|---|---|
| Under 3m | 2.5m mini gate | Mini barrier |
| 3 - 4.5m | 4m straight boom | Standard commercial |
| 4.5 - 6m | 6m straight boom | Premium / high-torque |
| Over 6m | Heavy-duty or dual gate | Industrial heavy duty |
Important: If your lane is exactly 6m, do not buy a 6m boom — you will not have enough clearance. Choose the next size up or use two gates.
This is where most buyers go wrong. A motor that is too small for your traffic volume will overheat and die within a year. Duty cycle (占空比) tells you how long the motor can run continuously without overheating.
| Daily Cycles | Typical Site | Motor Required |
|---|---|---|
| Under 300 | Residential community | Light duty, 60-100W |
| 300 - 1,000 | Office building, shopping mall | Medium duty, 140-200W |
| Over 1,000 | Hospital, logistics park, toll | High duty continuous, 200W+ brushless |
| Boom Type | Best For | Max Length |
|---|---|---|
| Straight arm | Standard outdoor parking | 6m |
| Folding arm | Low-height underground garages | 5m |
| Fence arm | Residential, anti-climb security | 5m |
| Advertising light box arm | Monetized entrances, branding | 4 - 4.5m |
We get asked this almost every day. Here is the short answer:
Unless you have a very tight budget and the site is indoor industrial, always choose DC24V. The small price difference pays for itself in 2 years of avoided maintenance.
A barrier gate is never a standalone device. It connects to your LPR camera, RFID reader or access control system. Before ordering, confirm which protocol your system uses:
| Protocol | What It Does |
|---|---|
| Relay output | Basic on/off signal. Universal compatibility. |
| RS485 / Modbus | Two-way communication. Required for integrated parking systems with LPR cameras. |
| TCP/IP | Cloud-connected, remote monitoring and management. |
If your gate is installed outdoors, do not skip these checks:
Send us your lane width, daily traffic volume, and boom type requirement.
We will recommend the right model with a factory-direct quotation within 24 hours.
