Abstract
Disclosed herein is a chain for use in a street sweeper in conveying dirt swept from the street along an inclined surface to a hopper for later disposal. Flights for conveying the dirt along the inclined surface are easily attached to the chain. The chain is of an offset configuration and is run open end forward. The offset configuration run open end forward results in less chain and sprocket wear than prior art straight sidebar configurations. Chain components are carbonitrided for high hardness. The distance the flights can be pivoted from the surface they contact is limited by strategic location of flight attachment portions of sidebars. Assembly is simplified.
