Where should first lift and transoms be placed on a cantilevered scaffold?

The correct placement of first lift and transoms on a cantilevered scaffold is as close to the needles as possible. This positioning is crucial for maintaining the structural integrity and stability of the scaffold. By placing the first lift and transoms near the needles, the load is more effectively distributed and supported at the point where the scaffold extends away from the building or structure. This helps prevent any excessive leverage that could lead to tipping or instability, which can be particularly dangerous during scaffolding operations.

Positioning the elements close to the needles ensures that the weight is more directly supported, mitigating the risk of structural failure. This alignment also allows for safer working conditions for those using the scaffold since the platform is solid and secure.

While the other answers may suggest various placements, they do not prioritize stability and safety in the same way that positioning the lifts and transoms close to the needles does.
