![]() Intercom systems: Intercom stations are often provided at automatic gates to give visitors and delivery drivers a means to contact someone inside the facility when the gate is closed. In most commercial installations, automatic gates are controlled by the same access control system that is used to control the entrance doors to the buildings, allowing the same access card to be used in both places. Some of these include:Īccess control systems: Automatic gates can be operated by a variety of access control devices, including card readers, vehicle tag readers, digital keypads, and portable wireless transmitters. There are many accessories that may be used in conjunction with automatic gates. This can be a problem at sites that have limited space available beside the gate. One downside to using cantilever gates is the additional width required to accommodate the counterbalance. Because of this, cantilever gates are considered to be much more reliable than slide gates, and are commonly used for heavy-duty and industrial gate applications. This section is called a "counterbalance" and is usually at least 1/2 the width of the gate opening itselfĬantilever gates are suspended across the gate opening from the counterbalance, with no rollers running along the ground to provide friction or to become obstructed. Cantilever gates need to be much wider than slide gates in order to provide a section along the fence structure where the gate is supported. This gate gets its name from the fact that the gate "cantilevers" (hangs over) the gate opening. Instead, the cantilever gate is supported from rails that run along the inside of the fence structure. The cantilever gate is similar to the slide gate, but does not use rollers that slide along the ground to support it. The following is a brief description of each type of gate: These include the slide gate, cantilever gate, swing gate, vertical lift gate, vertical pivot lift gate, bi-folding gate, and barrier arm gate. There are six types of commonly used automatic gates. Gate operators are electrically-powered and may be chain-driven, gear-driven, or hydraulic depending on the type of operator. Gate Operator: The gate operator is the machinery that moves the gate in and out of the gate opening. Most gates used in commercial applications are made of either ornamental iron or chain-link material and are usually designed to match the fencing adjacent to where the gate is installed. Gate: The gate is the physical object that is moved to block the gate opening. For example, automatic gates are commonly used within the inside of a parking garage to separate employee parking areas from public areas of the garage.Īutomatic gates consist of two basic components: ![]() ![]() Automatic gates are also used at interior areas within a facility. All vehicles entering and exiting the plant must do so through the automatic gate. For example, a manufacturing plant may use an automatic gate at its main entrance. Most commonly, automatic gates are used at the entrance to the facility, and are used to control vehicular access on and off of the site. Automatic gates are used to control access into a secured area.
