PURPOSE: To facilitate housing and extension of a cargo-carrying stand by detecting the angles of both upper and lower links when the load-carrying stand is housed, and stopping operation of a raising cylinder while starting operating of a housing cylinder if the angles detected have reached a predetermined value.
CONSTITUTION: A cargo truck 1 has a rotating shaft 8 supported to the rear end of a truck body 2 on which cargo boxes 5 are installed, and the rotating shaft 8 is connected to a housing cylinder 11 via an arm 10. A cargo-carrying stand 16 is connected to the rotating shaft 8 via a fist mounting member 12, upper and lower links 13, 14 and a second mounting member 15. A lift cylinder 22 is disposed in the first mounting member 12. When the cargo-carrying stand 16 is housed, the lift cylinder 22 is operated so that an angle sensor detects the angles of both the upper and lower links 13, 14. After the angles detected have reached a predetermined value, th operation of the raising cylinder 22 is stopped while the operation of the housing cylinder 11 is started.
