<p>The rear dump car has a sieving device (33) of a compulsive vibration type for classifying by size granular cargo at the front part of a cargo box. The device is disposed at the rear part of the cargo box and is capable of moving up and down. A sieve undercargo room is inside the cargo box at the lower rear part of the sieving device. A rear dump truck is equipped with a hopper (32) for accepting the granular cargo at the front part of the cargo box. A feeder (35) feeds out the cargo to the rear part of the cargo box, at the bottom of the hopper. A power gate system (36) controls the passage of cargo and is disposed at the outlet of the feeder and the sieving device. At the time of landing of the granular cargo that has been transported by other transportation such as ships, the granular cargo is directly loaded to the front part of the cargo box of the rear dump truck and transported by it. Before the granular cargo is unloaded from the rear dump truck at the destination, the classification work by the sieving device is effected and the granular cargo is unloaded in accordance with the classified sizes at the destination.</p> |
