Which setup helps ensure even load distribution when using more than two slings?

Explanation:
When lifting with more than two slings, the load will share across slings according to the geometry of how they’re attached and the angles they form. Using symmetric attachment points keeps each sling at similar angles and depths, so the tensions in the slings are balanced rather than one sling carrying more load than the others. A spreader beam helps maintain that even geometry by keeping the load from sagging or pulling unevenly on the slings, which further promotes equal load sharing and reduces peak tensions. The other approaches don’t reliably achieve even distribution. Relying on light-load use of a spreader beam ignores the need to maintain proper load geometry for heavier or complex lifts. Attaching slings at different heights creates unequal angles and unpredictable tension, increasing the risk of uneven loading. Tightening slings to the point the load can’t move addresses movement but not load distribution, and can overstrain one sling or distort the load.
