It's pretty much impossible to tell what's happening without taking a look at the setup. Assuming you're using pin constraints to attach the box to the crane hook, first thing that comes to mind is the offset of the pin constraints could be wrong.If you can describe your setup in more detail we might be able to help.

This is my setting

Nothing wrong there, except maybe 300 distance constraint iterations are a tad too much.

Double check that the particles near the cube have the same phase value as the cube's ObiCollider, else they will collide with it and fight with the pin constraints.

I fix distance constraint 300 to 3 but can't solve.
In Obicollider is phase is 0

I think something is squeezing it

I don't know what is keeping pushing it where it belong

I Change Thickness to -0.05. It can solve this problem Thank for your help
