A roof truss manufacturer specifies that trusses can only be lifted at designated lift points. The general contractor's crew wants to lift them at the peak for convenience. What should be done?

Option A: Allow lifting at the peak since it's the strongest point

The peak is actually one of the weakest points for lifting because it concentrates all the weight on the top chord connections and can cause the truss to bend or buckle. The peak was not designed to handle the entire weight of the truss as a lifting point.

Option C: Lift at quarter points for better balance

Quarter points are not necessarily the correct lifting locations unless specifically designated by the manufacturer. Using arbitrary lifting points, even if they seem logical, can still cause structural damage if they weren't engineered for that purpose.

Option D: Use additional workers to support the truss during lifting

While additional workers might provide extra support, this doesn't address the fundamental issue of using incorrect lifting points. The structural stress and potential damage from improper lift points cannot be prevented simply by adding more workers.
