Features:
1. Intelligent: Auto-detects opening and closing position in high accuracy by both mechanical and electrical limit detector. Combination of special inner working design and smart motor ensures swift and smooth arm movement in falling and lifting to reduce bouching.
2. Durable: Extension spring is more durable than compressed spring in heavy-duty site where barrier gate will open and close continously. AC motor can support long-lasting working of barrier gates. Cooling Fan processor is for decreasing working temperature.
3. Secure: Arm will be self-locked in any position to avoid unauthorized person to manually operate arm.
4. Safe: Arm will reversed back when it meets any obstacle in its movement. Optional rubber arm can avoid any damage when arm touches anything.
5. User friendly: Interfaces for photocell, loop detector, arm light, ect are reserved. No need to change spring if arm is changed (Eg. Arm is changed from 3m to 6m, the same spring can support.)
