<p>PROBLEM TO BE SOLVED: To provide a truck device capable of elevating a work placing base without using a driving device such a motor.SOLUTION: A truck device includes rolling wheels for travelling; a work placing base capable of being elevated/lowered to a truck body, and on which work can be placed; and first and second power storage devices 3 and 4 for elevating the work placing base. In the first power storage device 3, power is stored by the rolling of the roling wheels through power transmitting means 9 and 10. In the second power storage device 4, power is stored by the lowering movement of at least the work placing base due to self-weight through the power transmitting means 9 and 10. A resultant output control mechanism is provided, which merges the power stored in the first and second power storge devices to output. The work placing base is elevated by the merged power, thereby elevating the work.</p> |
