Stair Towers vs. Scaffold Ladder - Which to Use?

When it comes to accessing scaffolding platforms, contractors increasingly favor stair towers over traditional ladders. But which is the better choice for your project? Both scaffold ladders and stair towers have unique advantages depending on the job’s specific needs. Here’s a breakdown of their benefits to help you decide.

Advantages of Stair Towers

Enhanced Safety

Stair towers significantly improve safety. According to the Bureau of Labor Statistics, 1/7th of all fatal fall injuries are from falls off ladders. Stairs provide fall protection with side rails extending all the way up, minimizing the risk of fatal accidents. Unlike ladders, which can be treacherous in windy, wet, or cold weather, stair towers offer stable access in various conditions.

Faster Access

Stair towers allow multiple workers to move simultaneously and in different directions, providing faster access to the scaffolding platform. While ladders are like a slow one-way street, stairs function like a two-lane road, facilitating quicker and more efficient movement.

Improved Tool and Material Handling

With stair towers, workers can carry tools and equipment safely, reducing the need to use forklifts for transporting materials. This efficiency means crews can set up and start work faster, minimizing downtime and increasing productivity.

Advantages of Scaffolding Ladders

Space Efficiency

Scaffold ladders are ideal for tight spaces. While stair towers require a 5' x 7' footprint, scaffold ladders only need about 1.5' x 1.5'. This makes ladders more practical in constrained areas where space is at a premium.

Quick Assembly

Scaffold ladders are faster to assemble and require fewer materials. They are practical for projects with limited ingress and egress or when the scaffolding platform is not very high. This makes them suitable for smaller or less frequent access needs.

Conclusion: Stair Tower vs. Scaffold Ladders

When to Choose Stair Towers:

• Medium to large-scale projects requiring frequent access. 
• Sites where worker safety and productivity are critical. 
• Weather conditions that make ladders unsafe.

When to Choose Scaffold Ladders:

• Small or temporary projects with limited access needs. 
• Sites with tight spaces or low platform heights. 
• Situations requiring rapid assembly and disassembly.

We recommend using stairs to access your scaffolding whenever possible. Not only are they safer in virtually every situation but they will also increase productivity on medium to large project.
