Keyframe animations for objects

I´m breaking my head trying to find out a way to make it work in Blender but I cannot. Here´s a link with the files I´m using in case someone could have a look:

It´s a very simple example of translation, rotation and scaling but I cannot make it work in Unreal. Any Blender users here that can show me what settings I need for both packages to make it work?

Thanks in advance.
