“The major feature of Leda’s Security undercarriage cantilever gates is that they are only supported at one end and are designed to operate without the need for a surface mounted track across the driveway – beneficial in high traffic or heavy vehicle areas”

Motorised Cantilevr Sliding Gates

Trackless sliding gate systems do not require a ground track – this can be advantageous where the driveway entrance slopes, busy or heavy traffic entrances or where minimal disturbance to the driveway surface is requested. The main design difference from a tracked system is that the cantilever system has a special section bottom rail in which incorporates two sets of enclosed roller wheels set apart at a pre- determined distance to a large concrete foundation base.

The cantilever sliding gate is approx 1/3 longer than a tracked slider, the extra length acts as a counterbalance so that the gate is free to slide back and forth, supported throughout the entire opening/closing width by the roller wheels within the bottom rail. There is a slam post assembly at one end and stops at the other end to ensure that the gate cannot slide free of it mountings and fall over. Often the lower leading edge has a wheel which engages into a guide/shoe to ensure correct engagement upon closing.

The gate is held up-right by a guide rail and a roller. Guides positioned at the mid or top rail height. In the manual mode the gate is very easy to slide open and closed as the roller wheels incorporate precision bearings. The method of automation is based on a rack and pinion principle, the motor unit has a drive gear which engages into a linear rack positioned on the lower inside face of the gate, the motor gear wheel simply drives the gate open and closed.

What types of cantilever gate do we offer?

C4G offers several types of cantilever chain-link sliding gates in the Fortress family of products:

Box frame cantilevered slide gates- Fortress box-frame cantilevered slide gates are our largest type of sliding chain-link gate, capable of clearing openings up to 120 feet wide. Made from aluminum alloy extrusions, they are durable and lightweight for smooth, seamless operation, even in heavy-duty applications. A series of diagonal cross members reduce sway for improved structural integrity.

Heavy-duty cantilevered slide gates- Our strongest and toughest sliding driveway gate, Fortress heavy-duty systems are built for the most demanding applications. Like our standard gates, they are made from rugged aluminum alloy extrusions, but bolstered by a set of cross and top members for additional rigidity and stability. They are suitable for use in openings up to 60 feet wide.

Structural cantilevered slide gates- Fortress structural cantilevered slide gates offer a compromise between heavy-duty and standard products. Thanks to a double-track design, they can be used in larger openings – up to 80 feet wide – without compromising security or stability.

Ornamental cantilevered slide gates- A chain-link rolling gate should be more than just functional. For corporate and commercial applications, we offer a number of ornamental options that give you the security you need along with an appealing aesthetic. Choose from a range of color and design configurations – contact a representative directly for details.
