What is the correct use of a spreader bar in a multi-point lift?

• A. Attach the spreader directly to the load at a single point to maximize lift.
• B. Attach the spreader to the crane hook and connect slings at equal distances to distribute load evenly and maintain level lifting.
• C. Use the spreader only when lifting non-symmetric loads, and connect all slings to the same side.
• D. The spreader should be removed during the lift to reduce complications.

Answer: (B)

Using a spreader bar in a multi-point lift is about turning one lifting point into multiple, so the load is distributed evenly and stays level. The best way is to attach the spreader to the crane hook and connect the slings at equal distances along the spreader. This balanced arrangement ensures similar tension in each sling, keeps the load’s center of gravity aligned with the hoist, and prevents tilting or side loading that can stress slings, the spreader, or the crane hook.

Attaching the spreader directly to the load at a single point creates a point load and defeats the purpose of distributing forces. Using the spreader only for non-symmetric loads or connecting all slings to the same side would cause imbalance and tilt. Removing the spreader during the lift would remove the mechanism that maintains even distribution and level lifting, increasing the risk of instability and accidents.
