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.

Mechanism types

Electric

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, articulated arm swing gate operators and underground swing gate operators and motors for sliding gates. Electric and automatic gate openers are designed for both sliding and swinging gates and fences. 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 ensure function during blackouts or loss of electricity.

Hydraulic

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

Safety

It is vital to consider the safety of an electric gate. An unprotected automatic gate is a potential hazard for users. As such manufacturers offer a range of safety accessories including photoelectric cells, safety edges and induction loop systems.
