Apparatus for lifting and transporting drywall panels has a pair of panel-supporting legs of square tubing attachable to side rails of a lift platform. Each leg is connected to the rails by an upper bracket at the top of the leg and a lower bracket at a middle location. A panel-receiving U-shaped channel is located on the opposite side of the legs, away from the rails. The lower bracket has a standoff member projecting the bottom of the leg outward at an angle. A roller at the base of the channel provides low-friction rolling contact with an inserted panel, and a groove in this roller serves to guide the panel. Rollers at the tops of the legs and elsewhere are placed to keep panels from being damaged by contact with the legs.
