Rail System for Extruder

[arepnoy]

Hello,

I am not having a good luck finding a rail system for our extruder. The only company I found is

http://www.strothmann.com/en/roundtrack-systems/

but it appears to be an in-floor system. The extruder weights ~2000kg and I would like to place it on above floor rails so that it can move/compensate for expansion. Please let me know if you have any ideas or companies I should pursue.

Thanks
