PURPOSE:To control the movement of gravity center caused by the vertical movement of bucket to a minimum by a method in which a number of arms are connectedly set with pivot shafts to make up a link mechanism, and the arms of the pivot shafts near the horizontal position of bucket are orderly turned to vertically move the bucket. CONSTITUTION:A bucket 10 is supported through a link mechanism 9 on the vehicular frame 2. The mechanism 9 consists of a pillar 11, an arm 12, a lift mechanism 13, and a dump mechanism 14. The arms 15, 21 and 24 are connected with pivot shafts 17, 20 and 26 in a turnable manner. The arms 15, 21 and 24 are turned in order from one at the nearest pivot shaft point in horizontal distance with the bucket 10 to vertically move the bucket 10.
