Roller conveyors consist of rollers that are mounted on a series of axles attached to rigid fixed or telescoping frames. The rollers let loads roll along a path from one place to another.They provide a stable surface for moving loads with rimmed or uneven bottoms, such as drums, pails, pallets, skids, and bags.  Roller conveyors typically have a higher weight capacity and are better suited for moving heavy loads than skate wheel conveyors . Roller conveyors are often used in warehousing, package handling, manufacturing, and distribution applications.
