PURPOSE:To efficiently discharge earth and sand or the like, by providing a discharging wheel on the side of a container tiltable sideward around an axis on the other side and by engaging the wheel with a guide rail whose height gradually changes to invert the container by 180 deg. as a mining truck moves. CONSTITUTION:When plural mining trucks 1 coupled together are moved on rails 6 to the vicinity of a discharging pit 7, discharging wheels 4 are engaged with a guide rail 15 which is laid alongside the rails 6 to curve over the trucks 1 to the discharging pit 7 and whose most curving part is positioned at the opposite side of the pit. As a result, the container 3 of each truck 1 is gradually tilted toward the tip 7 along the guide rail 5 and finally inverted by 180 deg. to discharge all earth and sand out of the container into the pit. After that, the container 3 is gradually returned from the inverted posture to the original one as the mining truck 1 is moved further. |
