As a result, the panel end surface gripping device 40 is located above the panel P. At this time, if the distance between the two gripping portions 41a and 41b is smaller than the distance between the opposing end faces of the panel P, the nut with handle 5
1 is rotated by a required amount in the retreating direction with respect to the long screw 52, and the handle-equipped nut 51 and the long screw 52 are pushed forward to widen the gap between the two grip portions 41a and 41b. It is preferable that the handle-equipped nut 51 be in contact with the rear end of the screw sheath 53 in terms of workability thereafter.

Subsequently, the handle portion H of the hand-wound winch 20 is rotated in the direction in which the wire W becomes longer, and as shown in FIG. The elevating arm 30 (that is, the panel end surface gripping device 40) is lowered to a position facing the both end surfaces of P. In this state, the nut with handle 51 of the panel end face gripping device 40 is rotated a required number of times in a direction in which the nut advances with respect to the long screw 52. At that time, nut 51 with handle
Abuts against the rear end of the screw sheath 53, the advancement of the nut 51 with the handle is restricted, whereby the long screw 5
2 is retracted with respect to the screw sheath 53, and as shown in FIG. 13B, the distance between the two grip portions 41a and 41b is reduced, and the opposite end surfaces of the panel P at the uppermost position are gripped.

After the uppermost panel P is gripped in this way, the handle H of the manual winch 20 is rotated in the winding direction of the wire W, and the lifting arm 3
0 (panel end surface gripping device 40) is raised while the panel P is gripped. Then, while holding the panel P, the construction panel transport device is pushed and moved to a desired position.

Next, after moving the construction panel conveying device to a desired position, the handle portion H of the hand-wound winch 20 is rotated in the opposite direction to the front direction to elongate the wire W, whereby the lifting arm 30 (panel) is moved. Edge gripping device 4
0) is lowered, and the panel P gripped by the panel end face gripping device 40 is lowered to a predetermined place such as a floor. continue,
Nut 51 with handle of the panel end face gripping device 40
Is rotated in the direction of moving backward with respect to the long screw 52 to separate it from the rear end of the screw sheath 53, and the nut 51 with the handle is pushed forward together with the long screw 52 by the distance. Thereby, the interval between the grip portions 41a and 41b is widened, and the grip of the panel P is released.

After that, the handle portion H of the manually wound winch 20 is rotated to wind up a required amount of the wire W, the panel end face gripping device 40 is raised, and then the construction panel transport device is moved to the stacking position of the panel P by pushing. Then, the next panel P is transported.

When it is necessary to attach a fixing bracket or a leg 60 to the front or back surface of the panel P,
As shown in FIG. 6, while holding the panel, the turning lever L is tilted in the horizontal direction to raise the panel end face holding device 40 together with the panel P, and in this state, the turning lever L is locked. The part K is locked to maintain the upright state. In this state, a fixing bracket or the like is attached to the panel P, and then, the rotating lever L is returned to the original position in the front again to bring the panel end face gripping device 40 (that is, the panel P) to a horizontal state, and to carry it to a desired place. I do.

In the above embodiment, the case where the panel size is smaller than the width of the cart 11 has been described, but the panel may be larger than the width of the cart. In the case of a large panel, a space for the carriage to enter the lower side of the panel is secured, and the guide pipe 43 and the like of the gripping device are positioned outside the lifting arm 30 in order to secure the gripping force of the panel. And it is sufficient. Then, the body frame 10
It is possible to easily deal with a panel of an appropriate size without increasing the size of the panel. In this case, if the gripping device 40 is configured to be detachable with respect to the lifting arm 30 at the bearing member 38 portion, versatility can be further enhanced by preparing gripping devices of several widths. In the above-described embodiment, the screw mechanism has a long screw 5
2 can be slid so that nut 51 with handle is long screw 5
2, but the long screw 52 is rotatably attached to the connecting portion 46 with a bearing or the like, and the screw sheath 5 is screwed.
3 is screwed into a long screw 52 as a female screw to
b may be fixed to the rear end of the long screw 52. In this configuration, the rotation of the long screw 52 advances and retreats (the gripper 4
1a and 41b), which is suitable when the width of the panel to be gripped does not greatly differ depending on the type.
