If security is a concern, a video surveillance camera should be installed. Since electric gates operate slowly, they are susceptible to "tailgating" threats, in which a person or vehicle sneaks in behind an authorized user. Various safety devices are available to make sure that your gates meet the highest of European or American safety standards. An automated gate that has not been fitted with safety in mind can potentially become a major hazard particularly to untrained users. The safety of an automated gate is an important consideration, in the European Union, automated gate safety is specified by a series of European Normalisations. This is the electric device which actually enables the electric gate to open and close without having to manually push the gate. The backbone of any electric gate, whether automatic or not, is the electric gate motor, two distinct motor types exist hydraulic, or electromechanical. 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. The cost of the hydraulic systems however meant that other companies started producing more affordable electromechanical alternatives. The first commercial electric gate systems were hydraulic and designed for reliability and ease of use. At the end of the 19th century, electric gates were also used at horse racing tracks. 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. “A catch connected with an electro-magnet keeps a gate closed,” reported The National Tribune on October 9, 1884. In 1884, a number of American newspapers reported that the French railway companies were about to adopt an electric gate opener. It was designed to be used for railway systems. One of the first electric gates was invented by a Canadian Fred W. Sliding gates are also used for cantilever gate systems. Sliding gates are also very popular in a commercial environment. If space is an issue or the driveway behind the gates is on a steep incline, a better option would be a sliding gate. Also the manual release is always above ground, making it often more user friendly in operation. Therefore, Rams are far more suitable on Multi-user & commercial systems. 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. 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. Another major consideration with the use of under-gate units is that of water immersion/ingress and warranty voidance. For this reason they are recommend as only suitable for ‘Domestic’ systems in a low risk of abuse environment. This is highlighted with snap, as the gate has to change direct, as soon as it can. 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 makes the unit ideal cosmetically and also allows for up to 180 degrees of leaf swing as required. Under-gate Jack operators usually control the gate by directly moving the pivot point of each gate leaf. Also known as Crank arm operators, they are the main type of automation system sold in France, where low aluminium gates are often used. An easy system for DIY installers as they are simple to install but not as aesthetically pleasing as other motor designs. They are usually operated by a remote controller or a sensorĪrticulated gate openers can be used for gates with wide posts allowing opening in small spaces. Note also the Infrared obstacle sensor located on the wall to prevent the gate from closing while a vehicle or other obstacle is in the way.ĭriveway 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.
