When approaching the gate, the driver of the vehicle does not need to ready himself to get out of the vehicle in order to open the gate, as would be usual in rural farming instances. And the driver does not require the use of a remote to open and close the gate, as would usually be the case in suburban and commercial settings where property owners and their employees would be required to open their garage doors. Furthermore, farm gate openers, unlike other contraptions in any setting, require the use of very little power indeed.
These farm gate openers run on batteries which, in any case, have the ability to dispense as little energy as possible whilst powering a particular device to carry out its tasks. In this case, opening gates. Not just any gates, but farm and rural gates, usually located within rather isolated settings. So already, the reader can already see an advantage of installing such a gate opener as an aid towards providing safety and security. To reiterate, the driver of a vehicle does not need to leave his seat in order to open and close the impending gate.
What happens instead is this. The driver, needless to say, slows the vehicle down. Slowly, slowly, it continues to move into the gate. It nudges it, very gently. In this action, a trigger is set off and the gate subsequently opens. Wide. And of course, the driver and his vehicle can now go through. It is entirely his choice but he could now continue driving without much further ado. Because once he and his vehicle are through, the gate will close by itself. The user of this gate opener only needs to set in a timer which triggers off the countdown within a few seconds.
