PURPOSE: To enable troubleshooting of a traveling driving mechanism of a truck to be automatically performed by issuing an alarm when the fact that one of a first truck wherein a first traveling driving mechanism is arranged and a second truck wherein a second traveling driving mechanism is arranged is stopped for a specific period or more is detected.
CONSTITUTION: A first traveling driving mechanism 30 for reciprocating a first truck 10 in the direction to traverse between front and back side wall parts 2, 3 in a grain storage tank 1 and a second traveling driving mechanism 40 for reciprocating a second truck 20 in the direction to traverse between right and left side wall parts 4, 5 are arranged. While the first truck 10 is reciprocated once, an operating rod 96a of a limit switch 96 provided on the second truck 20 is once brought in contact with an operating pin 97, so as to be oscillated.
