Description of the Related Art In excavation work associated with the construction of an underground structure, sediment excavated in an underground ground is carried out by a dump truck placed in the underground ground, or a dump truck for carrying out earth and sand depending on the site and construction process. In the case where the vehicle cannot be operated to the underground excavation ground, the excavated earth and sand is lifted up from the earthlifting machine installed on the ground with a bucket hanging down via a wire rope and discharged. Conventional underground excavation uses a hydraulic excavator, and the excavated earth and sand is loaded on the dump truck or a conveyer vehicle is used as a relay transportation means for accumulating the excavated soil at the excavation site. A conventional conveyer vehicle that performs such relaying of earth and sand has a structure in which a conveyor is mounted on a lower traveling body via a turning device.
