The electrically operated gate opener features a fully sealed mechanical and electrical integration structure, suitable for outdoor use, and utilizes worm gear and worm drive. It is equipped with stroke limit and torque protection devices. The stroke limit device consists 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 limit rod, causing the hard contact limit switches to activate, automatically stopping the opening and closing action of the gate. In case the stroke limit switch fails to activate due to any reason, the torque protection switch triggers, safeguarding the opening and closing mechanism from accidental 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 the operation of the opener to remove moisture inside the electric unit, ensuring dryness and reliable operation of all electrical components. The gate nut is connected to the output end of the electric unit using a spline connector, which has gaps to create a锤击 effect when the gate opens, achieving the purpose of锤击启动 and increasing the pre-force during the gate's opening and closing. The cast iron bracket has a closed structure to bear the weight or counterforce during gate operation, is internally fitted with bearing supports, and has an exquisite appearance. It can be controlled on-site or remotely, allowing manual to electric automatic switching.

Features: 1. Comprehensive functions, reliable performance, advanced control system, compact size, lightweight, and easy operation and maintenance. 2. Features include overload shutdown protection, accident alarm display, and up/down stroke limit control. 3. Equipped with manual/electric switching mechanism, featuring 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 ratings: IP55 (special orders for IP65, IP67). 5. Instant torque protection: When the opening or closing torque is momentarily overridden, the gate stops without action. Even if the torque switch is momentarily overridden and closed, the gate will not move until it moves in the opposite direction, thereby releasing the over-torque protection. 6. Phase-loss protection: Features power phase-loss and output phase-loss protection functions.
