A pallet jack has a rotatable forked platform that match the pallet arms of the host fork where the host fork has embedded rollers. The rotatable forked platform has gaps that enclose the rollers embedded in the host fork to provide a smooth surface like that of a conventional pallet jack. The rollers are located at intervals from the front of the host fork to the rear of the overlay platform. When the forked platform is raised to expose the rollers, the rollers work in conjunction with an inclined ramp, also having embedded rollers, attached to the front of the arms to lift a container onto the forks. Once a container is aligned in front of the inclined ramp, the pallet jack is driven forward. The momentum of the pallet jack causes the inclined ramp to lift the container onto the arms.
