1. The unique infrared collision avoidance system ensures safety of passengers and vehicles by running backwards automatically at a distance 20-25cm away from a person or an object. 2. The alarm function works while someone climb the gate. (Optional) 3. Electronic soft startup strengthens operational smoothness by reducing rolling and inertial damage of the head. 4. Double self-lock to prevent any manual lifting. 16. Contact-free control in the whole circuit to ensure the system in safe and reliable operation. 5. Multi protection devices are designed to prevent the occurrence of car smashing. 6. Increasing safety and reliability of the motor by replacing the common temperature sensing protection with current sensing protection function. 7. Displaying words and time on LED, the words may be input up to 1000 words according to customers requirements and language. (Optional) 8. Anti-wind device ensure that the gate can resist the stack of strong wind. 9. Magnetic limit switch to ensure running the correct position.
