The first thing you want to consider when choosing the right automatic gate opener is the type of gate that you have. There are swing gates and sliding gates. With swing gates the gate opener may have a swing arm that extends to the gate which opens the gate. They can also use ram arms which are situated at the gate posts.
With sliding gates, the automatic gate opener will often feature a chain at the bottom of the gate that is connected to an operator, which then pulls the chain to open the gate.
How heavy your gate is in an important factor to consider. Some gates may be too heavy for automatic gate openers to function. Nonetheless, you should go for a model that has enough torque to open the gate efficiently.
You need to consider the source of power for your gate opener. Most models will work with an AC source but will also accommodate a battery or solar panels. The best models allow you to work with any of these sources to ensure a constant power source. You don't after all want to find yourself locked out during a power outage.
Due to the fact that gates are large, automatic gate openers are designed to be powerful equipment. However, this also means that they have the potential to cause injury or damage to property. It’s therefore important that your choice model comes with safety features such as a stop and reverse support when it hits an obstacle.
The best automatic gate opener will come with external interfaces to facilitate the control of the gate such as remote control, infrared sensors, as well as utility features.
Lastly you want to check the warranty. The best quality automatic gate openers come with extended warranties as the manufacturers are confident that they will last a long time. However, you are also covered in case something goes unexpectedly wrong.
