The retractable pitch entrance tunnel is often used in stadiums for the players to enter the field. The tunnel patented by Kopron can be expanded or compressed horizontally or vertically, thanks to a whole range of transmissions executed by the pantographs and high resistance belts, that make sure that the structure rises when it is extended and lowers when it is compacted.

Pitch entrance tunnels
This structure has been installed in the Meazza Stadium of Milan and used with great success. The tunnel protects the players when going onto the pitch, covering the area from the changing rooms to the pitch itself the cover of the entrance tunnel can be easily changed, guaranteeing the possibility of illustrating the various teams that may play in that stadium.
