Automated gates are a common addition to the security of many modern properties. Not only does this innovation save a person from being vulnerable to hijack as they climb out their car to manually open a gate, but it is also a major convenience and time saver.
Here is a brief look at the inner mechanics of the two types of automated gates; both sliding and swinging in design.
The “slide variety” is the more commonly used of the two and its core mechanics are based around a simple drive cog, the purpose of which is to propel the gate on a steel rack. This drive cog is powered by an oil cooled reduction (or epicyclical) gearbox, which is in turn powered by an electric motor, either AC or DC. The over all power of the motor can vary greatly, being determined by the RPM (revolutions per minute) and “reduction ratio” of the gear box.
Although utilising a “ring gear formula” as apposed to the oil cooling box of the sliding designed gate, the swing motor works on a similar RPM and gear ratio principal.  In more specific detail; the gear turns onto a drive shaft, which in turn pulls an arm that is attached to the gate via a universal joint.
The piston system, making use of a “worm gear” design, is also often used in conjunction with swing gates. This mechanic, however, generally operates slower than the previously mentioned systems.
All designs of motors can be fitted with, (or often come standard with,) a built in battery backup system in case of power outages or malfunctions that restrict electricity flow. Since motors tend to vary greatly in cost, depending mostly on the strength and durability of the motor in question, it is wise to factor in a battery option when making a choice.
The remote controls that wirelessly operate gate motors are mostly, by default, very simple in appearance and functionality. The majority consist of a single button, although multi-button versions are available and can be programmed to operate more than one motor IE, a garage door.
