electric sliding gate with electric motor gear and rack and pinion guide with limit switch, sensor An electric gate is a type of gate that can be opened and closed by an electrically powered mechanism. Electric Gate Options An electric sliding gate with an electric motor and a backup battery in case of a power failure. Also note the infrared obstacle sensor located on the wall, which prevents the gate from closing when a vehicle or other obstacle is in the way. Driveway gate openers can be of the rolling (sliding) type, which moves the gate along a fence or wall on wheels or bearings, or the swing type, which opens or closes the gate on hinges. They are usually operated by remote control or sensor Articulating Articulating gate openers can be used on gates with wide posts, allowing opening in small spaces.[1] An easy system for DIY installers, as they are simple to install but not as aesthetically pleasing as other motor designs. Also known as crank arm operators, they are the main type of automation system sold in France, where low aluminium gates are often used. Underground Under gate lift operators usually control the gate by directly moving the pivot point of each gate leaf. This makes the device aesthetically perfect, and also allows the leaf to rotate 180 degrees if required. However, controlling the gate pivot point is like opening a door by turning a hinge, and is therefore very difficult due to the loads needed at this point. This is accentuated by the latch, as the gate must change direction as quickly as possible. For this reason, they are recommended as only suitable for “domestic” systems in an environment with a low risk of abuse. Another important consideration when using under gate devices is water immersion/ingress and will void the warranty. If the groundwater level is high or the drainage of the foundation box of the device is insufficient throughout the life of the system, then water ingress and failure of the device is increased. The lifting arm or link arm type devices are usually simpler to install and maintain, are visible to otherwise unaware misuse and because they are fixed along each gate leaf, they also have obvious and sometimes significant mechanical advantages over lifters. Rams are therefore much more suitable for multi-user and commercial systems. In addition, the manual release is always above ground, which often makes them more user-friendly to operate. Sliding If space is an issue or the driveway behind the gates is on a steep slope, a sliding gate will be a better option. Sliding gates are also very popular in commercial environments. Sliding gates are also used in cantilever gate systems.
