<p>PURPOSE:To make a carriage go up or down smoothly as preventing its inclination from occurring, in the carriage conveying a die, a work, a work pallet or the like in an L-shaped form in the horizontal direction. CONSTITUTION:An inner frame 1, an outer frame 2 and a mechanical lifting gear 3 are all installed there, and each traveling wheel 4a of the inner frame 1 and each traveling wheel 4b of the outer frame 2 are oriented orthogonally travelable with each other. The mechanical lifting gear 3 consists of one electric motor 5 and four jack mechanisms 6 and a power transmission mechanism 7. The inner frame 1 is assembled in the outer frame 2 via each jack mechanism 6 free of relatively vertical motion. With this constitution, these four jack mechanisms 6 are synchronously driven by one electric motor 5 via the mechanical power transmission mechanism 7.</p> |
