Roller gates use wheels to make them portable and collapsible. They can be used to protect areas from outside interference or enclose specific areas, such as in the event of a dangerous spill. They are used in large-scale applications, such as runway closures or military base exercises, and in many major airports around the world. Smaller roller gate applications can be used to make opening and closing a simple apparatus like a chain link fence gate easier and more efficient.
A roller gate is a fencing system that uses different configurations of rollers or wheels. These wheels allow the gate system to become portable, even in situations where the roller gate is considered heavy or industrial. The gate system is usually collapsible upon itself so that the extended length of the gate can be changed as needed.
The length of the gate can be changed to protect an area from outside interference or to enclose a specific area. For example, it can be used in the event of a dangerous spill. In cases where an entire area has become unsafe, the use of roller gates can also be employed to prevent people from entering the contaminated area.
One type of gate is a contained roller gate. These are used in large-scale applications, such as runway closures or military base exercises. The roller gates in these cases are often fixed to the ground through channels running in the asphalt so that the roller gates can be deployed whenever needed. These channels often contain a guide system consisting of angled steel rods running the length of the channel, with concave rollers for the gate system to allow it to slide properly on the angled guides and prevent the system from derailing its intended path.
The roller gate systems used in many major airports around the world are automated. This means they can be deployed to seal off an area within minutes of realizing the need. They can be used to protect the airport or even national security, or they could be used as a simple redirection technique to redirect a landed plane to the correct gate. In order for these gate systems to remain secure, however, they must also have some sort of connection method between the roller system and the channel that the rollers pass through. This is usually achieved through the use of specially designed clips that keep the gate system tires or rollers locked within the designated track.
Smaller roller gate applications can be used to make opening and closing a simple apparatus like a chain link fence gate easier and more efficient. These roller door mechanisms are much easier to install and maintain than the larger roller door systems used in airport and industrial settings. Some may even have motors installed on them, so they become automated and allow or prevent an individual from passing through a gate. These systems typically use only one or two wheels at most, and the limited wheels often slide on the ground or on an angled track bolted to the ground below the gate.
