Frequently Asked Questions
What is a cantilever gate and how does it work?
A cantilever gate is a type of sliding gate that does not require a ground track to operate. Instead, the gate is suspended on specially designed carriage assemblies that are securely mounted to concrete footings or support posts. A heavy-duty C-shaped steel channel welded to the underside of the gate glides smoothly over the carriage wheels as the gate opens and closes. Because the gate is supported above the ground, it can operate reliably over gravel, uneven driveways, snow, mud, or other obstacles that would interfere with a traditional tracked gate. This design provides smooth, low-maintenance operation and is commonly used for residential, commercial, and industrial entrances.
What’s the difference between a cantilever gate and a tracked sliding gate?
The primary difference is how each gate is supported. A tracked sliding gate rolls along a steel track installed on the ground using wheels attached to the bottom of the gate. While this design is cost-effective, the track can collect dirt, leaves, stones, or ice, which may affect performance and require regular cleaning. A cantilever gate, by comparison, is fully supported by carriage assemblies mounted beside the opening, allowing the gate to slide without touching the ground. This makes cantilever systems ideal for uneven surfaces, sloping driveways, or locations where debris regularly accumulates. However, because a cantilever gate requires a counterbalance section behind the opening, it is typically longer and uses more steel than a tracked gate.
What is the channel in a cantilever gate system?
The cantilever channel is a heavy-duty C-shaped steel profile that is welded or securely fixed to the underside of the gate. It extends along the full length of the gate, including the counterbalance section, and forms the track that rides over the carriage wheels. As the gate moves, the carriage wheels remain stationary while the channel glides over them, creating smooth and stable movement. The enclosed design helps protect the moving components from dirt, moisture, and weather, reducing maintenance requirements and extending the life of the gate system. Choosing the correct channel size is essential for supporting the gate’s weight and ensuring reliable operation.
What is the counterbalance, and why is it important?
The counterbalance is the section of the gate that extends beyond the opening on the closing side of the gate. Although it does not block the entrance, it plays a critical structural role by balancing the weight of the gate as it travels over the carriage assemblies. Without a correctly sized counterbalance, the gate can become unstable, sag, bind, or place excessive stress on the carriage wheels and support posts. The required counterbalance length is generally calculated as a percentage of the clear opening, depending on the gate design, weight, and wind loading. Properly sizing this section is essential for safe, reliable, and long-lasting gate performance.
How do I choose the right channel for my gate?
Selecting the correct cantilever channel depends on several factors, including the overall gate weight, gate length, wind exposure, and the type of infill material used. As a general guide, the GTR024-2 channel is suitable for gates weighing up to 1200 kg, while the heavier-duty GTR025-2 is designed for gates up to 1800 kg. Gates with solid steel, aluminium, or composite infill create significantly higher wind loads than open mesh designs, meaning a larger channel may be recommended even if the gate falls within the lower weight range. Always consider both static weight and environmental conditions to ensure safe operation and long-term durability.
What wheel sets match the GTR channels?
Each cantilever channel is engineered to work with a matching carriage assembly for the best fit and performance. The GTR024-2 channel is designed to be used with the GTR027 five-wheel carriage set, while the GTR025-2 channel is paired with the GTR028 five-wheel carriage set. Using the correct combination ensures the wheels fit the channel profile correctly, providing smooth operation, even weight distribution, and reduced wear over time. Mixing incompatible channels and carriage sets can result in poor gate performance, excessive wear, or unsafe operation, so matching components is always recommended.
Can I cut the cantilever channel to length?
Yes. Cantilever channels are typically supplied in 5.8 metre lengths and can be cut to suit your gate design. Before making any cuts, it is essential to calculate the total required gate length, including both the clear opening and the counterbalance section. Removing too much material can compromise the structural integrity and balance of the gate, potentially making it unsafe or preventing it from operating correctly. If you are unsure of the required dimensions, it is best to complete the gate design calculations or consult the manufacturer’s recommendations before cutting the channel.
Does the ground under the gate need to be level?
No. One of the biggest advantages of a cantilever gate is that it does not rely on a ground track, allowing it to operate above uneven or challenging surfaces. The gate can slide over gravel, grass, sloping driveways, paving, or areas where water and debris would normally interfere with a tracked system. However, while the ground beneath the gate does not need to be perfectly level, the support posts, carriage assemblies, and gate itself must be installed accurately so they are level, square, and plumb. Correct installation is essential to achieve smooth movement, minimise wear, and ensure the gate operates safely for many years.
Cantilever Gate Hardware
Richmond supplies a professional range of Cantilever Gate Hardware designed for trackless sliding gate systems used across residential, commercial and industrial properties. Cantilever gates operate without a ground track, making them ideal for sites where uneven surfaces, debris, mud, gravel or heavy vehicle traffic make traditional sliding gate systems unsuitable.
Unlike standard sliding gates that rely on wheels running along a ground track, cantilever gates are fully supported by overhead or side-mounted roller systems. This allows the gate to “float” above the driveway surface while moving horizontally. The result is a low-maintenance sliding gate system that continues operating reliably in harsh outdoor and industrial environments.
Richmond’s Cantilever Gate Hardware range includes cantilever rollers, guide channels, mounting brackets and gate support components suitable for both manual and automated gate systems. These components are engineered for smooth gate travel, long-term outdoor durability and reliable operation under load.
Richmond also supplies Gate Hardware, Gate Motors, Automatic Gate Hardware, Sliding Gate Hardware, Swing Gate Hardware, Gate Post Caps and Hanging Door Hardware for complete gate and access system solutions.
Trackless Sliding Gate Systems for Industrial & Commercial Applications
Cantilever Gates are commonly used where traditional sliding gate tracks are impractical or difficult to maintain. Because the gate is suspended above the ground rather than rolling along a track, cantilever systems avoid issues caused by dirt, stones, water, mud, snow, leaves and general debris buildup.
This makes Cantilever Gate Hardware particularly suitable for industrial facilities, commercial sites, farms, logistics centres and high-traffic access points where forklifts, trucks and heavy vehicles regularly cross gate openings. Without a ground track, there is less risk of impact damage, obstruction or ongoing maintenance requirements.
Cantilever systems are also beneficial on sloped driveways, uneven surfaces or sites with poor drainage where conventional sliding gate tracks may become unreliable over time.
