Automatic gate openers use a motor of some type to open gates from a distance. There are many different kinds of gate opening systems, and if one does not work for you, then switching to another system may address the issues you are struggling with. Power sources, types of gate movement and detection methods are only some of the aspects that can be changed.
Swing and Sliding
Generally, gates can either swing or slide open. Sliding gates open by moving out toward the sides of the gate in parallel motion, ending in predetermined slots. Sliding gates require some sort of ground-based pulley system or sheath that the gates can slide in and out of. These are simplest types of gates for motors to operate. Swing gates swing inward or outward to open. The swinging motion is often harder for motors to control, so larger motors are needed that can produce more power. Swinging gates are used when there is not enough room for a sliding gate or when a swinging gate looks better for cosmetic reasons.
Button and Detection
With electric gate openers, there are generally two ways the gate is told to open or close. The first way is by remote, the same way a garage door works. A remote sends an infrared or radio wave signal to the motor of the gate, which then opens, and closes again when a second command is given. Detection systems use either infrared beams or pressure plates to detect when a car has pulled up to the gate, which may then open or simply be activated to wait for a further command.
