Animation of features like hoses requires regeneration which cannot be done in mechanism or animation.
Linkages can be animated, Ones where assembly constraints force components to move with other components. Springs and chains have been made to do this.
Depending on the quality you need for the animation, you might be able to link "capsule" like segments and treat the cable like a chain by linking the "capsules".
I have done this with cable tracks and I can tell you it really takes some patience to assembly these. Not to mention the CPU power required to move things like this in real time (using drag component).
Alternatively, you can have a lot of hose models in different positions for each frame. in Animation, you can turn components on and off along the timeline. In your case, you can simply swap hose displays between frames. If you get clever, you can do this fairly quickly with family tables in the hose part.
Alternatively, you can capture frame by frame and assembly this in another program like PhotoScape and make an animated GIF file.
PTC really needs to add the ability to regenerate between frames in both mechanism and animation. This is a serious flaw in what is otherwise a valuable feature. It doesn't seem to have been touched for over a decade.
