A carrier having a wheeled, open-ended, frame pivotally the frame and cradle can be maneuvered around a pot and under projections on the pot. A pair of primary linear actuators on the frame are coupled through levers and links so as to cause the cradle to lift the pot for transport and thereafter dump the pot by tilting the cradle more than 140 DEG while maintaining good mechanical advantage. Secondary cylinders are positioned to bear traveling loads, eliminating the pressure in the primary cylinders and the forces through the links and pins. The levers and links are designed so as to avoid twisting and binding under heavy loads. |
