What is a Cantilever Scaffolding System?

When to Use Cantilever Scaffolding

Cantilever scaffolding is typically used when the ground surface does not allow for the installation of traditional scaffolding systems or when it is not feasible to build scaffolding from the ground up. Thus, under typical conditions, setting up a cantilever scaffolding system is ideal when the ground surface is stable.



Limitations of Cantilever Scaffolding

Other limitations that the ground surface is unable to support the weight of conventional scaffolding include uneven or obstructed surfaces. In such cases, a cantilever scaffolding is a suitable solution as it extends horizontally from the building or structure, providing a stable working platform without relying on vertical supports from the ground.

There is no single fixed maximum length for a cantilever scaffold, as the safe extension varies depending on factors such as load capacity, the type of materials used, and the strength of the supporting structure. Engineers determine the allowable projection by applying Australian Standards for load-bearing and stability, ensuring that the scaffold can withstand the required stresses. Regardless of project size, every cantilever system must be assessed and certified by a qualified engineer before use.

The main difference lies in how each system is supported. Cantilever scaffolding relies on needles that extend out from the building to carry the load, making it suitable where ground space is limited. Truss-out scaffolding, on the other hand, is supported by a truss structure anchored firmly to the building, allowing it to handle heavier loads. In short, cantilever scaffolds are often chosen for lighter tasks and restricted access, while truss-out scaffolds are more robust and used for larger-scale or heavy-duty work.

Cantilever scaffolding is commonly used when additional support is needed to reach elevated surfaces and hard-to-reach areas of buildings. It is especially useful for scaffolding applications in tight spaces or near the edges of high-rise buildings. This includes roofing repairs and cleaning, window installation, bridge construction, building maintenance or other tasks that require workers to gain access to upper floors and areas that can't be reached by a regular scaffolding system.

What are the different types of cantilever scaffolding?

There are a few types of cantilever scaffolds commonly used in construction and maintenance work. If you're unsure which type is best suited for your project, a scaffolding for hire company can provide guidance. Here are some common types:

Needle Scaffolding

Needle beam cantilevered scaffolding consists of a horizontal cantilever beam or a horizontal work platform that are supported by needle beams resting on the building or structure under construction. This type of scaffold is commonly used for tasks such as plastering, painting, or repair work.

Double-Frame Cantilever Scaffold

In this cantilevered scaffolding, the two frames that are securely affixed to the building offer enhanced stability and increased load-bearing capacity to support more substantial tasks and instances requiring a larger working platform.

Counterbalanced Cantilever Scaffold

Counterbalanced cantilevered scaffolding uses counterweights that are placed on the opposite side of the cantilever to achieve load balance. This type is commonly used in situations where space is limited on the side of the building or when it is difficult to secure the scaffold to the building.

Trussed Cantilever Scaffold

Trussed cantilever scaffolding uses diagonal bracing and truss-style structures to improve stability and increase load-bearing capacity. This type of scaffold is ideally used on construction and maintenance activities.

Suspended Cantilever Scaffold

A suspended cantilever scaffold is a type of scaffolding structure that is suspended from overhead supports and extends outward, allowing workers to access and work on exterior surfaces of buildings and other high structures.

Rolling Cantilever Scaffold

Mobile or rolling cantilever scaffolding is equipped with wheels or casters, enabling convenient mobility as required. This scaffold structure is ideally used for projects that demand constant relocation.

Joint Tower Scaffold

Joint tower scaffolding or also referred to as modular scaffolding is a type of scaffold that is used commonly in several construction projects due to its strength, adaptability, and ease of assembly. This type of scaffold consists of standardised components like vertical standards, horizontal ledgers, diagonal braces, and connectors that are ideally used to provide a stable platform to workers.

Takeaway

Cantilever scaffolds are a very versatile type of scaffold that can be used in different types of construction projects as they provide a stable platform for workers operating in tight spaces and at high elevations. To enhance site safety, systems are equipped with protective rails, safety harnesses, and other measures that prevent workers from accidents, keeping both the person on the platform and those on the ground secure. Scaffold components are manufactured to be all the same size, which ensures stability and consistency during assembly.
