Uindia Automation offers cantilever system for gates, someplace practically not possible bottom track that time uses cantilever system for the gate.
A Cantilever Sliding Gate will remove the need for tracking along the length of the opening. A cantilever gate is suspended over the entrance with horizontal posts. Cantilever gates are quieter than the traditional floor track systems.
However due to the nature of the cantilever design an additional section of the gate is required to 'hang' over the carriage units, often behind a wall or hedge perimeter. This means that additional room is needed beside the gate opening than a tracked version and may prevent you from choosing this option.
A simple way to look at this system is that you have two carriage units that look like upside down roller skates and a track the runs on these rollers. The gate sits on top of this track.
In summary, do not use a cantilever system unless the ground is uneven, when your sliding gate is running across the ground it won't move or drop.
