Overground Gate Automation System – Linear Operators
Hi again. Here's your next option for automating Swing gates. Suitable for new or existing gates - here's the Overground Gate Automation System.
Per a previous post - there are several types of overground gate automation system. In this post I will explain the Linear Operator for you.
The Linear operator is quite a simple, yet very reliable system for operating gates. If you can remember back to your secondary school maths or physics? There was a simple mechanism called a "screw jack" - that perfectly describes it. In fact, it works in exactly the same way as a car jack (if you've ever changed a wheel).
An electric motor turns a long screw. And as it turns, the pivot for the gate travels along the screw (top open or close the gate). Its reliable, because it uses a small force to move a heavy object - the same as a car jack! The motor turns the screw in one direction to open and the opposite direction to close the gate.
Overground Gate Automation System Suitable For Wooden and Metal Gates
The linear operator is suitable for use on wrought iron gates and solid hardwood gates. In fact, it is the ideal solution for wooden gates as the motor can't be forced open. So it will hold a wooden gate open or closed, securely in windy conditions. The operation is very smooth and very quiet.
There are a few different formats in the linear operator - but the operation is exactly the same. The difference being, that some models are suitable for use where the distance from the back of the gate to the back of the pillar is 100mm or less. Other versions can manage up to 150mm.
The linear operator, overground gate automation system, also comes with a manual release mechanism. Generally locked in place with a keyed lock, they are really easy to use. Especially as they are at a more convenient height to access - as opposed to the underground gate automations system. This is positioned under the gates. In the event of a power cut - you simply unlock the release and pull the lever - and you can swing the gate open or closed by hand. It doesn't matter what position you re-engage the manual release in. The motor will always find it's "home" position.
As with the underground operators - the overground gate automation system comes in a mains voltage (230v AC) and low voltage (24v DC) variants.
The low voltage variant is more often used on gates where they will be operated quite frequently - such as on an apartment complex or where there are multiple homes behind the one gate. The low voltage system can also be fitted with a battery back-up system - which will keep the gates operating for a number of cycles, should the mains electricity supply be off for a time. This is a very convenient facility to have - especially if there are elderly users of the gate.
That's all for this post. I hope you find it informative and interesting to read.
