The present invention solves the above-mentioned problems, and when a heavy object such as a multi-layered panel is lifted and lifted by a crane or the like, a construction worker does not support the heavy object, It is an object of the present invention to prevent damage to a lower member due to contact with a lifted heavy object.

[0005]

In order to solve the above-mentioned problems, according to the present invention, the holes of the upper lifted member are formed at the end faces of the pair of vertically lifted members opposite to the hoisting side. The first receiving member to be inserted into the hole, the second receiving member to be inserted into the hole of the lower lifted member and locked inside the hole, and the base end sides of these receiving members are respectively moved up and down. And a lower end of the support member, which protrudes downward from a rotation fulcrum of the second receiving member and which is lower when the upper lifted member is lifted. It is characterized in that it is an abutting portion that abuts on the end face of the lifted member. Further, in the above, the support member is configured by a pair of left and right side plates, and between the side plates, a pair of upper and lower rotating frames are attached rotatably in the vertical direction via shafts extending between the side plates, It is also conceivable to attach the receiving member to each tip of the rotating frame.

Further, it is conceivable that the rotating frame is formed in a U-shape when viewed from the top, and two left and right receiving members are respectively provided on the center piece thereof at intervals.

It is also conceivable to provide an operating handle on the rotating frame so as to project in the direction opposite to that of the receiving member.

The receiver of the present invention can be applied not only when it is lifted by a crane or the like but also when it is necessary to lift one end for some purpose such as when the panel is turned over.

[0009]

When one end of the lifted member is lifted by a crane or the like, the upper receiving member inserted into the hole of the lifted member rotates about its rotation fulcrum, and at the same time, the supporting member also receives the lower receiving member. While pivoting about a pivotal support with the member as a fulcrum, the opposite side of the lifted member is held.
