As shown in FIGS. 1 to 3, the hanging member 1 for a plate material has a frame-like frame fixed in parallel to a vertically opposed position via a supporting portion, and a substantially central portion of the upper surface of the upper frame 2. Is attached with a hanging hand 2a. The lifting hand 2a is carried by a pair of reinforcing plates 2b attached to the inside thereof.

On the upper surface of the lower frame 3, a pair of guides 4 are formed in parallel in a horizontal direction at a position opposed to the center of the hanging tool 1. On the guides 4, a gantry 5a of a pair of arm units 5 is provided. It is slidably disposed along the guide 4. On the other hand, a brake motor 6 for driving the arm unit 5 is provided substantially at the center of the lower frame 3, and two identical chain wheels 8 are coaxially supported by a speed reducer 7 directly connected to the brake motor 6. ing.

At the center of both ends of the lower frame 3, two identically shaped chain wheels 8a are rotatably supported, and the corresponding chain wheels 8 and 8
a, each endless roller chain 9
Are engaged. The bottom surface of the base 5 a of the arm unit 5 is connected to each roller chain 9. With the above configuration, by rotating the brake motor 6 in the normal and reverse directions, each arm unit 5 reciprocates in the opposite direction at the same distance along the guide 4 from the center of the lower frame 3 as a base point.

A pair of downwardly-shaped L-shaped arms 10 are attached to the upper surface of the gantry 5a so as to extend and contract in opposite directions. That is, two pairs of rollers 11 are pivotally supported at the base of the horizontal portion of each arm 10, and are held so as to be able to expand and contract along a box-shaped guide 12 fixed to the gantry 5a. Guide 12 is horizontal and guide 4
And the arm 10 is connected to the arm unit 5
