Electric gates are powered by electricity. So, what happens to them when there’s a power cut, or the workmen dig up the road and cut off the electricity? And how do the gates open and close when they need electricity to work?
What is a Common Gate Set-up?
The most common gates are swing gates and sliding gates.
Sliding Gates
Sliding gates are the simplest, as the gate has wheels which run along a track across the driveway entrance. A toothed rack is mounted along the length of the inside of the gate. A gear on the outside of the sliding gate motor meshes with the rack on the gate. Consequently, when the gate motor turns, the gate is opened or closed.
Swing Gates
Swing gate motors are a little more varied, but all use one of two basic operation principles. An electric gate motor either turns an arm mounted to the gate to open or close it, or it moves the point where it connects to the gate toward or away from the point where it is connected to the gate post; this opens and closes the gate.
How Do You Operate Electric Gates Manually?
The method used to operate electric gates manually, when there is no electricity to power the motors, is called manual release. This involves the use of a manual release key and built-in manual release mechanism, or a separate additional manual release mechanism.
The manual release key is usually inserted into the appropriate lock on the motor housing, then a lever or handle is operated to disconnect the motor drive from the gate opening arms, gears and shafts.
