How to Position Acrow Props Correctly for Maximum Safety?

Working in construction? Need to support masonry, load-bearing beams, or any other structure that requires vertical load-bearing support? Acrow props are your go-to solution. These adjustable steel supports are vital in ensuring temporary structural stability during building or renovation. However, knowing how to position Acrow props correctly is just as important as choosing the right type. Improper placement can lead to structural failure, site delays, or serious safety risks.

At Australian Scaffolds, we supply only compliant, high-quality Acrow props designed for Australian conditions. Below, we outline key tips on positioning Acrow props to maximise both safety and performance on your job site.

1. Start with a Solid, Stable Surface- Safety

Begin by placing your Acrow props on a firm, level surface that can handle the intended load. Whether you’re working on a concrete floor indoors or softer soil outdoors, make sure the ground can support the full pressure transferred through the prop.

Consult a structural engineer to assess site conditions, particularly for indoor jobs where floors or joists may not be structurally sound. When needed, use base plates or sole boards to spread the load evenly and prevent slipping or sinking.

2. Position Props Close to the Wall

Place Acrow props as close as possible to the wall or structural element you’re supporting. This setup helps prevent the incorrect use of strongboys or timber needles, which must fully penetrate the wall cavity to perform effectively.

When you position props too far from the wall, you reduce their load-bearing strength and increase the risk of bending or failure. Keeping them tight to the structure ensures maximum support and structural safety.

3. Keep Props Fully Vertical- Safety

Always position Acrow props in a perfectly vertical, upright alignment. Even a slight tilt can significantly weaken their load-bearing capacity. If your job site doesn’t allow for a vertical setup, switch to a different scaffolding support system better suited to the angle.

Acrow props are engineered specifically for vertical loads—using them at an angle increases the risk of collapse.

4. Use One Prop Per Metre (Minimum)

Place at least one Acrow prop per metre along the load-bearing span. This guideline helps distribute weight evenly, reduces the load on each individual prop, and adds redundancy to the support system.

Should one prop fail unexpectedly, the surrounding props can still carry the load safely. More importantly, evenly spaced props help prevent damage to flooring or ground surfaces, especially indoors.

5. Choose the Shortest Suitable Prop

To safely position an Acrow prop, avoid extending it to its maximum height. Instead, choose the shortest prop that still meets your required working height. Shorter props offer greater stability, support a higher load, and significantly reduce the risk of bending or deflection.

For example, if your working height is 2.5 metres, select an Acrow prop that reaches that range with minimal extension—don’t rely on a model that extends up to 4.5 metres unless absolutely necessary.

6. Consult a Professional Before You Start

Even when you follow every best practice, always speak with a qualified structural engineer or scaffolding expert before beginning any structural work. Acrow props may seem simple, but their safe use depends on proper planning and expert oversight. On larger or multi-storey projects, the stakes are even higher—don’t take unnecessary risks.
