A vertical lift conveyor for lifting materials between different vertical levels. The vertical lift conveyor includes a pair of spaced uprights and a carriage that moves vertically along the spaced uprights. The vertical lift conveyor includes a drive assembly including a drive motor coupled to a drive shaft. Each end of the drive shaft includes a first sprocket and a second sprocket that each engages one of a pair of lift chains. The first and second sprockets each include a plurality of teeth (N). The first and second sprockets are offset from each other 180/N°. The offset between the first and sprockets creates sinusoidal velocity profiles for the two chains that are out of phase with each other. A connection block is used to connect the pair of lift chains to each side of the carriage combines the lift chain velocities into a linear vertical velocity for the carriage.
