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 50pound box. This pace is ideal for many—but not all—order picking and assembly operations. There are always situations where transport through an area, into a process, or toward a packing operation can be accelerated.
