As the name suggests, tracked systems employ a ground track along which slides the main gate leaf by means of two wheels or rollers housed within the bottom rail.
The gate is held up-right by a guide rail and two Guide rollers positioned at the middle or top rail, which in turn is supported by steel posts on the inside of the entrance.
In the manual mode the gate is very easy to slide open and closed as the roller wheels incorporate precision bearings.
The method of automating is based on a rack and pinion basis; the motor unit has a drive gear which engages into a linear track positioned on the lower rear face of the gate, the gear wheel simply drives the gate open and closed.
The motor incorporates a control card which can be set up to achieve the correct closing force and set open/close limits.
Sliding Gate Systems will need to include appropriate safety devices to ensure complete safety.
Safety requirements will be identified during a site survey/risk assessment and may include the following:-
Leading Edge Safety Strips
Induction Ground Loop Detectors
Force Limitation – Motors
Signage or warning lights
