PURPOSE:To make possible the 3-direction dumping by providing a rotary supporting shaft, which serves as a pivot shaft for dumping operation of a box- type deck in the direction opposite to the driver's seat, across the body and by setting a fulcrum pin, which operates for dumping in the direction perpendicular to the above direction, perpendicularly to the above rotary supporting shaft. CONSTITUTION:When earth and sand, etc. are thrown down in front of a vehicle, an opening 16 is turned upward by operating a clasper 17 of a rear pedestal A. Next, by extending a hydraulic cylinder 5 under the deck, the deck is tilted around a rotary supporting shaft 19 of a pedestal B and the earth and sand, etc. are thrown down frontward. To tilt a deck 3 leftward of the vehicle, the hydraulic cylinder 5 should be operated with the openings 16 of the claspers 17 on the right-side front and rear pedestals A, B turned upward. The deck 3 turns around the left side fulcrum pin 9, which intersects the rotary supporting shaft 19 at right angles, in the direction perpendicular to that of dumping operation, thus throwing down the earth and sand, etc. When the throwing down on the right side of the vehicle, the operations should be reverse to the above. |
