PURPOSE:To raise the efficiency of excavating operation by providing a bucket elevator to scoop and carry excavated soil onto a self-propelled vechicle, and a belt conveyer to carry and put the excavated soil on a dump truck. CONSTITUTION:A bucket elevator 8 is provided through a boom 6 to a truck 4, and a second oil-pressure cylinder 9 to determine the inclining angle of the elevator 8 is also attached to the truck 4. The elevator 8 is designed to enable an upper frame 22 and a lower frame 23 to be bent by a pivotal support shaft 24, and is also provided with a chain tension device to avoid the looseness of a chain 14 attached with a feeding bucket 15 when it is bent. First and second belt conveyers 26 and 27 to carry excavated soil which is sent to the upper end of the elevator 8 to a dump truck 28 are also provided.
