At this time, due to the winding operation of the wire 14 of the winch device 46, the vehicle base 7 connected by the wire 14 is light in the rear oblique lifting load of the guide frame body 5 with respect to the lifting load of the vehicle mounting base 7. In the guide frame body 5, the shaft 51 provided at the front is locked and held at the lower part of the notch of the locking claws 30, 30, and is raised from the position (c) of the shaft 51 to the position (d). The guide frame body 5 is held in position by contacting the upper notches of the locking claws 30 and 30, and the operating plate 52 provided on the shaft 51 is switched from ON to OFF by operating the upper limit switch 38. . However, since the upper limit switch 38 and the limit switch 75 are connected in parallel, even if the upper limit switch 38 is OFF, since the limit switch 75 is ON, the winch device 46 continues without interruption. Winding operation can be performed.

  When the shaft 51 comes into contact with and holds the upper portions of the notches of the locking claws 30, 30, the vehicle-mounted base 7 connected by the wire 14 is pulled by the wire 14 and moves forward, and eventually the guide. When the in-vehicle stand 7 moves forward to the specified position of the guide frame 5 in an overlapping state with the frame 5, the pin 74 of the in-vehicle stand 7 contacts and presses the limit switch 75, and the limit switch 75 is turned on. The winch device 46 is switched from OFF to OFF and the energization is cut off and held. The position of the limit switch 75 is adjusted so that the member 7b at the front center of the vehicle-mounted base 7 can be stopped at a position close to the cushioning material 47 fixed to the guide frame 5.

  Next, in order to bring the guide frame body 5 and the vehicle-mounted base 7 in the rear oblique state into a horizontal carrying posture, the following procedure is performed. First, as shown in FIGS. 10 and 12, when the release operation lever 17 provided on one side of the column 4 c of the column frame 4 is pulled by hand, the locking claw connected to the control wire 37. As a result, the shaft 51 of the guide frame 5 is not locked and held by the locking claws 30 and 30. When the winch device 46 is operated in the reverse rotation direction on the rewinding side of the wire 14 by operating the switch of the remote control lever 76 in this state, the wire 14 of the winch device 46 is drawn out, and the shaft 51 of the guide frame 5 is moved. The one that has been held in contact with the upper notches of the locking claws 30, 30 is lowered with the rear fulcrum portion of the guide frame as a fulcrum, and the vehicle is loaded with the guide frame 5 and the loaded vehicle 16. Table 7 descends.

  Then, the guide frame body 5 that has been in a rear oblique posture and the vehicle-mounted base 7 on which the loaded vehicle 16 is loaded are in a horizontal transportation posture. At this time, the movable guide frame 12 that is inclined rearward is restored upright by the tension of the spring 44, and the upper limit switch 38 provided on the movable guide frame 12 is provided with an operating plate provided on the shaft 51. Therefore, the upper limit switch 38 is switched from OFF to ON.
