Gate operator

A gate operator is a mechanical device used to open and close a gate, such as one at the end of a driveway. There are two main types of electric gate openers – hydraulic or electromechanical; these can be further split into the following categories, worm (or screw) driven, arm openers and underground openers. Automatic and Electric Gate operators are designed for both swinging and sliding gates. They can be programmed to open and close with a wireless transmitter or a manual device. Low Voltage Automatic Gate openers can also be fitted with solar panels to ensure function during loss of electricity or blackouts.

Operator Types


Drawing power from the mains to open a driveway gate. Generally there are four types of electromechanical gate operator: Worm driven (or screw type) swing gates, barrier arm operators and sliding operators Electric and automatic gate openers are designed for both sliding and swinging gates. They can be programmed to open with a manual device or a wireless transmitter. Automatic gate operators can also be fitted with solar panels to operate without high voltage power. Many manufacturers offer battery backup either integrated or as an add on to systems that ensure function during loss of electricity.


These are used to automatically open an electric driveway gate. As the name implies they use hydraulic fluids to operate their motion. Typically hydraulic operators have less moving parts than mechanical operators.

The hydraulic motors have a number of advantages when operating gates: they are capable of producing more power than mechanical motors for heavy sized barriers and do not have to work at full power when operating large gates.

Drawbacks of using hydraulic operated barriers are caused because of the technology itself, being under pressure, they tend to be harder to handle and less safe.
