I'd like to ask for some opinions here regarding a flat belt conveyor system that I've been ask to built.

Specs:
dimension: ~ 0.9 ft wide x 5ft length x 4ft height
Frame: assembled from aluminum extrusion profiles
work load: 0
maximum desired speed: 6.6 ft/s

Do you all think that for a such small scale conveyor system, the desired speed is too high??

What are the reliablilty issues that may occur.
