A cargo lifting apparatus for use with a ladder includes a lift track coupled to each ladder side rail. Each lift track includes first and second adjacent channels, the first channel defining a longitudinal slot. The apparatus includes a carrier assembly having a back portion, a pair of support members extending perpendicularly and forwardly from the back portion, opposed mounting members configured to be received in a respective first channel slot, and rollers attached to the back portion configured to bear against respective ladder side rails. A motor/brake combination is coupled to a lower rung of the ladder. A pulley assembly includes a lower sprocket operatively coupled to the motor, an upper sprocket, and a cord extending between the sprockets and coupled to the carrier assembly for selectively raising and lowering the carrier assembly when the motor is activated or deactivated.
