Articulated Arm Overground Gate Automation System

So, if you read my last post, you will be familiar with the principle of an overground gate automation system (that it is located above the ground!).

In this section, we will introduce another variation on that, which is the Articulated Arm Overground Gate Automation System. That's a bit of a mouthful, but that's as complex as it gets. I've also heard it referred to with a non-technical name - the "bendy-arm system". that's a great description as you will soon see...

These gates have been automated with an articulated arm system because the gates are hung in the centre of the pillars.

Articulated Arm Overground Gate Automation System

As I mentioned previously, there are several types of overground gate automation system. The reason for that is because of the different sizes of gates, different frequency of operating and the different way that gates are hung on pillars or posts. The Articulated arm overground gate automation system is suited for installations there the gates are hung on concrete or stone pillars. A pillar is normally 450mm or more in width and the gates are generally mounted around the centre of the pillar. This means that the distance from the back of the gate to the back of the pillar will be 200mm or more. That distance is too great for linear motors or ram operators - because of the geometry.

A domestic or light commercial articulated arm system is suitable for installations where the distance (gate to pillar) is up to approx 300mm.  (We have heavy duty systems that can manage 600mm plus - but we'll not talk about those here).

The principle behind the operation or mechanics is easiest described like this. Imagine standing in front of a door. You reach out and grasp the handle. Without moving your torso - think about how you pull the door open! You draw your wrist toward you, by bending your elbow. That's exactly how the articulated arm overground gate automation system works. Instead of having a rigid arm - it bends in the middle - just like your elbow.

The articulated arm operator has a "bendy arm" which fold up to pull the gate open.

As with all of our systems, you have a manual release mechanism incorporated, to enable the gates to be manually released. This is to allow the gates to be opened by hand if the electricity supply is off. These motors also come in a 24v DC variant, which will allow a battery back up system to be added. This back-up enables the gates to continue to operate for a number of cycles if the electricity is off. That's ideal where there may be someone elderly, disabled or infirmed using the gate.

What about reliability and safety?

In terms of reliability - these systems are great. As they are installed above ground, you don't have to worry about water or drainage. There are moving parts - so a little preventative maintenance is required, just to prevent wear.

You may think that the folding arm looks dangerous - especially for kids? No need to worry. These arms have no pinch points, so nowhere for little fingers to become trapped or nipped.

The articulated arm overground gate automation system is really reliable and the manual release mechanism is particularly easy to operate (should your electricity go off).

In summary, the articulated arm overground gate automation system is suited for automating new or existing gates.  Both wooden and metal gates can be automated with this type of system. They are designed to be used where the gates are hung on pillars because they can reach in to the centre of the pillar to attach to the gate. They are extremely safe and reliable. and they are easy to use and maintenance is low.
