What is the maximum allowable distance a ledger can be joined from a standard?

The correct answer is that a ledger must be joined no more than 300mm from a standard. This distance is significant in scaffolding because it ensures that the load distribution is effective and that the structural integrity of the scaffold system is maintained.

By limiting the distance of the connection between the ledger and the standard to 300mm, it minimizes potential sway and increases the overall stability of the scaffolding. When the ledger is positioned too far from the standard, it can create leverage points that may compromise the system under load, leading to potential failure.

Maintaining this maximum distance is critical for ensuring that the scaffolding adheres to safety standards and provides a safe working platform for users. In practice, this regulation helps ensure that the load is effectively transferred and that the entire system is capable of supporting the anticipated weight without excessive deflection or risk of collapse.
