By far the most popular way of automating electric gates is with the underground motor.
Once correctly installed, there is no apparent sign of the mechanism other than the lid of the foundation casing box, and the pivitol arm which the gate is attached to. This does not detract from the overall aesthetics of an attractive gateway.
The underground motor can be fitted to new gateways or most pairs of existing gates and are designed to automate either metal or wooden gates.
In the eventuality of a power cut the underground system has a key operated manual release mechanism which is conveniently situated on both the inside and outside of the gateway.
