Crane Hook Analysis consult

Hello everyone,

I am trying to do analysis to this crane hook, so created the geometry and everything runs fine. But when I try to place a force at a distance where (X,Y,Z)=(0,-50,0) everything goes red, but if I place the force at (X,Y,Z)=(0,-32,0) everything runs smoothly as the third picture.


So here is how I do it:  

First I would go and create a keypoint at the specified x,y and z, then I would fix the hook from the top. After that I would apply a force at the specified coordinates keypoint then solve.
