A gate operator is a mechanical device that is used to open and close an electric gate. The two main types of electric gate openers are hydraulic and electromechanical. Automatic and Electric Gate operators are designed for both sliding and swing gates. A wireless transmitter or a manual device can then be used to open and close the gates when leaving or entering the property. Automatic gate openers that use a low voltage can also be fitted with solar panels to ensure operation when there is a loss of electricity.
