ABSTRACT:
A method comprises a step of accessing a conveyor belt system that has a belt, a return roller, and a return roller support assembly. The return roller is supported by the return roller support assembly. The return roller is engaged with the belt from beneath the return run. The method also comprises operating the return roller support assembly in a manner causing the return roller to lower relative to the belt to a position where the return roller is no longer engaged with the belt, without requiring any person to reach beneath the belt. The method still further comprises removing the return roller from the return roller support assembly by sliding the return roller out from under the belt after the return roller has been lowered, without requiring any person to reach beneath the belt.
