When to Consider a Cantilever Gate: A Guide for NZ Architects and Installers

Introduction

Deciding on the right driveway or entrance gate for your client involves understanding how the gate will be used, the space available, and any environmental or site-specific challenges.

In many cases, cantilever gates can offer distinct advantages over traditional sliding gates and other driveway gate options. Architects and installers in New Zealand are increasingly turning to cantilever gates due to their unique benefits and practical applications.

What are Cantilever Gates?

As the name suggests, a cantilever gate system relies on a counterbalanced design, where the gate is supported by a horizontal beam that extends beyond the opening. This beam, combined with a set of rollers mounted on support posts, allows the gate to remain suspended above the ground as it slides open and closed. With a cantilever system, there is no need for a ground track, as you’d find with a typical sliding gate.

Benefits of Cantilever Gates

• Light yet strong: Aluminium cantilever gates are lighter than steel, making them easier to install. However, they are also strong and are used for their durability and ability to withstand high winds, making them ideal for New Zealand's variable weather conditions.

• No Ground Tracks: The absence of ground tracks makes cantilever gates perfect for uneven or unsealed surfaces, as well as environments where leaves or other debris are likely to collect in a ground track.

• Space Efficiency: Unlike swing gates that require plenty of space to swing in or out, cantilever gates slide alongside a fence line, making them ideal when there is plenty of room to slide along a boundary line. Assuming there is adequate space for the gate to return, you’ll need the opening width plus 30 percent for total gate length.

• Aesthetics: Any gate style can be made into a cantilever gate, providing the full range of options from laser cut designs, through to heavy duty security gates and everything in between.

• Security: The cantilever suspended design makes it difficult to force the gate open, making them a preferred choice for applications where heightened security is important.

• Automation: Cantilever gates are ideal for automation, offering smooth, reliable operation. They use sliding gate motors that are designed for horizontal movement. When automating a cantilever gate, it’s important to select a motor that is rated for at least twice the weight of the gate to ensure optimal performance. Beninca offers a range of motors specifically designed to suit cantilever gate systems, including BULL 1224.

Considerations for Cantilever Gates

While cantilever gates offer numerous advantages, certain factors should be considered:

• Wind Stability: In windy conditions, additional bracing may be required to enhance stability and prevent derailing.

• Installation Requirements: Proper installation is crucial to ensure smooth operation and longevity. This includes regular maintenance such as annual lubrication of rollers and wheels.

• Space Constraints: Due to their design, cantilever gates may require more lateral space compared to swing gates, making them less suitable for tight or compact areas.

Conclusion

In conclusion, cantilever gates present a helpful solution for architects and installers seeking a gate solution where the ground is uneven or unable to support a ground track, and/or where there is limited space in front or behind the gate but plenty of room alongside the fence line.

Cantilever gates also offer superior security. By understanding their unique benefits and considerations, professionals can confidently recommend and install cantilever gates to match the needs of the project.
