What does a spreader bar do?

• A. Connects braces to the slab
• B. Lifts loads directly from the slab
• C. Spreads apart the cables from which subsequent loads are suspended
• D. Anchors to the foundation

Answer: (C)

A spreader bar’s job is to distribute the lifting force across multiple points so the load is lifted evenly rather than from a single point. In tilt‑up construction, lifting a large panel from one spot can create unequal tension, twisting, or edge damage. The spreader bar connects several lifting slings to the panel at spaced points and keeps them apart, so the crane’s load pulls more or less evenly from across the top. This balances the lift, reduces concentrated stress on the slab, and helps the panel rise true and safe. It isn’t about connecting braces, lifting directly from the slab, or anchoring to the foundation—the spreader bar’s purpose is to spread the cables’ load.
