Sling forces in 4-point configuration
When there are more than three slings attached to one load, then the configuration is statically indeterminate. Therefore, one must consider the stiffness of the slings to compute the load in each of them. I am assuming that the load does not deform. Certifying bodies require this kind of calculation for four-point lifts. The hook load…

Sling forces
If there is a box on a pallet which will have to be lifted and you were asked to calculate the force in each of the three slings, then use vectors! Imagine a coordinate system with the x-axis along one edge of the pallet and the y-axis along the other and the z-axis vertical, then…
