A device for attaching to a ladder allows the ladder to function as a hand truck. The device includes a pair of retractable wheels. The retractable wheels can be stored away inside an outer profile of an opened or closed stepladder, so that the wheels do not interfere with a user when the ladder is opened and do not take up space when the ladder is closed. The device may also include a retractable carry platform for holding loads when the ladder is used as a hand truck. A reverse side of the carry platform can serve as a paint bucket support or work surface when the ladder is in use. Both the retractable wheels and the retractable carry platform are attached to the ladder by a frictional engagement which does not violate the structural integrity of the ladder.
