A gate or gateway is a point of entry to a space which is enclosed by walls. Gates may prevent or control the entry or exit of individuals, or they may be merely decorative. Other terms for gate include yett and port. The word is derived from old Norse "gat", meaning road or path, and originally referred to the gap in the wall or fence, rather than the barrier which closed it. The moving part or parts of a gateway may be considered "doors", as they are fixed at one side whilst opening and closing like one.

A gate may have a latch that can be raised and lowered to both open a gate or prevent it from swinging. Locks are also used on gates to increase the security. Larger gates can be used for a whole building, such as a castle or fortified town. Actual doors can also be considered gates when they are used to block entry as prevalent within a gatehouse. Today, many gate doors are opened by an automated gate operator.

Electric Gate Options

Driveway gate openers can be the rollback (sliding) type that retracks a gate along the fence or wall on wheels or bearing, or the swing type that draws the gate open or closed on hinges. The most popular electric gates for residential properties are swing gates.

Underground
Under-gate Jack operators usually control the gate by directly moving the pivot point of each gate leaf. This makes the unit ideal cosmetically and also allows for up to 180 degrees of leaf swing as required. However controlling the pivot point of the gate, is like opening a door by twisting the hinge, and as so is very difficult due to the loads needed at that point. This is highlighted with snap, as the gate has to change direct, as soon as it can. For this reason they are recommend as only suitable for ‘Domestic’ systems in a low risk of abuse environment. Another major consideration with the use of under-gate units is that of water immersion/ingress and warranty voidance. If the water table is high or the drainage of the unit’s foundation box inadequate throughout the systems life, then water ingress and unit failure is increased.

Ram or link arm units are usually simpler to install and maintain, they are visible to otherwise ignorant abuse and as they fix down along each gate leaf, they also have an obvious and sometimes major, mechanical advantage over Jacks. Therefore, Rams are far more suitable on Multi-user & commercial systems. Also the manual release is always above ground, making it often more user friendly in operation.

Electric Gate History

One of the first electric gates was invented by a Canadian Fred W. Watson in 1881. It was designed to be used for railway systems. In 1884, a number of American newspapers reported that the French railway companies were about to adopt an electric gate opener. “A catch connected with an electro-magnet keeps a gate closed,” reported The National Tribune on October 9, 1884. One of the early demonstrations of such gates in the United States was arranged by the short-lived Toulmin Electric Railway Gate Company in 1887, in Baltimore. At the end of the XIX century electric gates were also used at horse racing tracks.

The first commercial electric gate systems were hydraulic and designed for reliability and ease of use. The cost of the hydraulic systems however meant that other companies started producing more affordable electromechanical alternatives. Hydraulic motors are the preferred choice on large and heavy gates as they can generate high levels of torque, electromechanical systems designed for lower usage domestic installations because they can be produced more cost effectively.
