Unpowered pallet conveyor features a series of rollers laid in succession within the conveyor frame. The pallet moves manually along the track, and the rollers help keep the pallet in motion by reducing friction between the rollers and the pallet itself.
Calculating Conveyor Speeds What speed should your conveyor operate? Request Info. The standard speed for most unit handling conveyors is 65 FPM (feet per minute) which works out to the average speed a person walks when carrying a 50-pound box. This pace is ideal for many—but not all—order picking and assembly operations.
