Direct answer: Barrier maintenance is usually performed every 3-6 months at medium-density sites; at busy parking facilities and terminal entrances with thousands of open-close cycles per day, this interval should be shorter. Maintenance checks arm balance, motor/gear lubrication, the control board, and safety sensors (photocell, loop detector).
What is done during periodic maintenance?
In a standard maintenance visit, arm balance and spring tension are checked, the motor and gear assembly are lubricated with the manufacturer-recommended lubricant, the connections and fuses on the control board are reviewed, and the photocell and loop detector are tested for a correct signal. The condition of the reflective tape/LEDs on the body and arm is also checked.
What determines the maintenance interval?
Maintenance frequency mainly depends on the daily cycle count (vehicle transit density), the site's environmental conditions (dust, humidity, salty air, etc.), and the cycle capacity of the barrier model used. A high-density paid parking facility and a low-density villa entrance should not have the same maintenance interval.
What happens if maintenance is neglected?
An unlubricated motor/gear assembly heats up and wears out more over time; an out-of-balance arm places excess load on the motor; untested safety sensors create a security risk when they malfunction. Regular maintenance significantly reduces sudden faults and unexpected service costs.
