A multi-use dolly system suitable for art, sculpture, sheet goods, lumber, and furniture.
The basic over-sized dolly. Standard width of 18 inches. 42 inches in length. With 6 inch rubber wheels, swivel at on end, fixed at the other. Bolt on handle turns the dolly into a flatbed wagon. There's a catch for the handle so it doesn't flop around when carrying.
The panel rack sits on top, captured by the cross pieces. Works well for large paintings, panels, plywood, drywall, etc. The panel can be bolted on for rough terrain. Use a ratchet strap to keep items in place.
