A moveable track cover is provided for use with a mechanism configured to move along a track. One example of such a mechanism is a pipe racking system used on off-shore oil and gas platforms. One end of the moveable track cover is connected to the pipe racking system mechanism which moves along the track. The other end of the track cover is spooled onto a drum. Rotation of the drum is controlled by a motor which exerts enough force to maintain the track cover in constant tension. When the pipe racking system mechanism moves towards the drum, the motor rotates the drum to roll the track cover onto the drum. When the pipe racking system mechanism moves away from the drum, it pulls the track cover off of the drum. By attaching a track cover to each side of the pipe racking system mechanism, the track along which the pipe racking system mechanism travels is kept covered at all times. The track cover may be constructed of a sheet of stainless steel strengthened by rib assemblies. The rib assemblies may include wear strips to facilitate easy sliding of the track cover, and the top of the sheet will preferably have a non-skid material adhered to it to prevent workers from slipping on the sheet when they are walking across it.
