How to simulate motion with contacts at a point?

I am trying to simulate contact of a wire loop-like geomety in contact with a slope. This hook is riding along the x-axis and when it reaches the slope then instead of keep going along X it then raises along Y-axis.

This illustration has the wire loop and in front is the angled plane it needs to follow.

Any help will be greatly appreciated.

Thanks in advance,

Jorge
