A garage door opener is simply a mechanical tool designed to help open and close garage doors remotely. Looking back, garage door opening systems were first off made up of fairly simple remotes coupled with receiver. These two collectively supervised the opening and closing of garage doors. When being used, the openers transmit frequencies to and fro. With the correct reception of these signals, the garage door either responds by opening or closing automatically. It is equally important to note that the wireless door openers were yet another form of earlier door opener technology which was faced with an equal share of frequency issues.

Any contemporary door opener usually provides several transmission technologies. In fact, such a system requires at least 300 MHz frequency spectrum. What’s more, in most cases the transmitter or the receiver is usually dependant on the rolling code technology which serves to protect it from the recording of a code yet it is being replayed. With the transmission of code the rest of the system automatically generates a new code while the offset system of the garage door lifts the door using torsion springs. At the moment, most garage door openers have been fitted with remote control systems hence they are very easy to use and equally easily accessible in the market. Fortunately, part from the above, there are several other counterweight technologies which equally permit the doors to be easily moved without a lot of pressure.

Overall it is important to understand the fact that it is a trolley actuator that is used for residential doors. This is mainly because the entire system is usually attached with a motor and alongside a trolley. The motor is therefore left hanging near the ceiling where as the trolley is directly connected to the arm of the door. Finally when opened or closed, the door responds with a transversal or rail by the trolley.

There is also usually a jackshaft which serves as yet another type of actuator but functioning with a torsion spring technology. One interesting thing about this system is the fact that it is never attached to the door, instead it is attached to the spring shaft. Just so you know, it is this rotation of the shaft which usually permits the moving of the door. One of the main advantages of this system is the fact that it can easily be operated remotely without any form of help from the rail (which by the way is a very important component in a trolley actuator). In most cases the jackshaft actuator is usually not preferred owing to safety concerns since it makes it fairly difficult for the operator to know whether there is someone near the door that is likely to be crushed.

In addition to the above, it is important to understand and accept the fact that at the moment, a garage door opener is easy to find in today’s marketplace. This being the case, take time to familiarize yourself with all the commonly available options since this is the only way through which you can guarantee the efficiency of the garage door system as well as the security of your parking area.
