Conveyor belt: making bottom actor being child of top actor

Hi guys,
I´m currently working on a project, where I´m realising a conveyor belt by using splines.

I´m currently struggling with following problem:
I need to place an actor, which is on a low track, underneath an actor, which is running on a high track, so that the cube will be at the bottom of the cone.

I want to use a box collision which triggers the step.

BPs:
