There is a drive section at one end, having a drive motor and a drive roller and an end section having an end roller at the opposite end. A number of intermediate sections are located between the drive section and the end section. Each intermediate section contains a frame, one or more support legs, a coupling mechanism to couple to adjacent sections, and a belt support. The belt support is preferably a roller.
