Swing Gate Operators
There are five types listed below:
Swing Gate Operators with Arm On Top. These are the most common units and are the work horses of the industry. A high end unit can last up to 20 years. Most of these units have heavy gear reduction oil bath gear boxes. They are generally very heavy in weight, many weigh up to 100 Lbs. and are large in size. A couple of drawback to them is the arm has to be removed to remove the cover for service. Some of them have an access panel to service the controls, but you still need to remove the cover to service the mechanics. The other drawback is the arm generally ends up in the middle of your gate where it can be unsightly.
Swing Gate Operators with Bottom Arm. DoorKing is the only operator that has the arm on the bottom. In general, they are not built as heavy as the top arm units, but do last as long. The two benefits of this type of unit is that the cover pops right off to reveal the entire unit and is one of the easiest units to service
