The electrically operated gate operator features an all-enclosed mechanical and electrical integration structure, suitable for outdoor use, with worm gear and worm drive. It is equipped with stroke limiters and torque protection devices. The stroke limiter is composed of a set of counting gears and hard contact limit switches. When the gate is fully open or closed, the counting gears drive the stroke limiter rod, causing the hard contact limit switches to activate, automatically stopping the gate's opening or closing action. If the stroke limiter switch fails to activate due to some reason, the torque protection switch activates, protecting the operator from unexpected damage. The electric unit is also designed with a pointer-type opening indicator and a heating resistor. The pointer-type opening indicator is connected to the counting gears, providing a direct indication of the gate's opening position. The heating resistor automatically connects during operation to remove moisture from the electric unit, ensuring internal dryness and reliable operation of all electrical components. The gate nut is connected to the output end of the electric unit with a spline-type connector, which has gaps to create a striking action when the gate opens, achieving the purpose of striking start, and increasing the pre-force during gate opening and closing. The cast iron bracket has a sealed structure to bear the weight or counter-force during gate operation, and it is internally fitted with load-bearing bearings, with an exquisite appearance. It can be controlled on-site or remotely. Manual and electric automatic switching is available.

Features: 1. Full-featured, reliable performance, advanced control system, compact size, lightweight, and easy to use and maintain. 2. Equipped with over-load shutdown protection, accident alarm display, and up/down travel limit control. 3. Features manual/electric switch mechanism with automatic power cutoff. Both integrated switch type and integrated adjustment type can achieve on-site and remote control functions. 4. Outdoor and explosion-proof protection class: IP55 (special order: IP65, IP67). 5. Instant torque protection: When the opening or closing torque is instantaneously lifted, the gate will stop without action. Even if the torque switch is instantaneously lifted and closed, the gate will not move until it reverses once to release the over-torque protection. 6. Phase loss protection: Offers phase loss protection for both power supply and output.
