PROBLEM TO BE SOLVED: To provide a lifting/lowering device including functions in which pavement materials are stocked in a fixed position, moved to a higher position and further moved to the other position, and thereby contributing to an efficient conveyance of the pavement materials.SOLUTION: A lifting/lowering device comprises a receipt part 1 for receiving pavement materials and an inter-device movement mechanism 2 for moving the receipt part 1 in the device. The receipt part 1 includes a pyramid part 11 for storing the pavement materials and a frame body 12 surrounding the pyramid part 11. The inter-device movement mechanism 2 includes a parallel link 21 for lifting and lowering the receipt part 1 from a lower position to a higher position, and a hydraulic cylinder 22 for lifting one end 1a of the receipt part 1 and inclining the receipt part 1. The pavement materials received by the pyramid part 11 of the receipt part 1 are made to flow and transferred along the inclination to a bucket B of a transport heavy machine such that the receipt part 1 is lifted to the higher position as substantially in a horizontal state by the parallel link 21 and one end side 11a of the receipt part 1 in the pyramid part 11 is lifted and tilted by the hydraulic cylinder 22, and thereby a hopper device A is constituted. |
