The present invention relates to a lift device for an earth and sand transporting vehicle and is to efficiently transport earth and sand from excavation using an excavation vehicle by elevating the excavation vehicle using an elevation unit by rotational force provided from a power unit through a support unit installed in a vertical hole. To do so, the life device for an earth and sand transporting vehicle includes: an elevation unit (100) which elevates in the longitudinal direction of a vertical hole (1) and moves an excavation vehicle (4); a support unit (200) which is installed in the vertical hole and guides the elevation of the elevation unit; and a power unit (300) which is included in the support unit and provides elevation force to the support unit. The support unit is composed of blocks each of which includes: a plurality of fixing bars (212) which are arranged at regular intervals; and an upper and a lower support (214)(216) which are placed at the top and the bottom of the fixing bars and maintain the intervals among the fixing bars. Each of the fixing bars includes: an insertion hole (2122) which has a certain depth inside the upper part; and an insertion projection (2124) which protrudes a certain length from the lower part and is to be inserted into the insertion hole of an adjacent fixing bar. |
