Sliding gates
A sliding motor sits beside the gate and drives a toothed rack fixed along it. It needs a level track, enough wall space for the gate to slide into, and a motor rated above the gate's actual weight. Steel gates in Tanzania are often heavier than owners expect, so the weight is checked before choosing the motor.
Swing gates
Swing gates use one arm per leaf. They need clear space for the leaves to open, usually inwards, and solid pillars to mount the arms. Very wide or heavy leaves and steep driveways may make sliding the better option.
Safety, remotes and power cuts
Safety beams (photocells) across the opening stop the gate when something is in the way. Remotes, keypads or a link to a video intercom control access. A backup battery keeps the gate working for a number of open-close cycles during outages, and solar charging is available where mains power is unreliable.
Frequently asked questions
Can I open an automatic gate by hand?
Yes. Every gate motor has a manual release, usually opened with a key, so the gate can be moved by hand if the motor or battery fails.
Can my old manual gate be automated?
Often yes, if the gate is straight, runs freely and is in good condition. Rollers, track and hinges may need repair first.
