Here, the luggage placing member is supported by an arcuate rail provided on a horizontal portion of the elevating member, and the luggage placing member is provided on the elevating member so as to be located at the center of the arcuate rail on one side of the guide rail. The lock mechanism can be mounted on the vertical fulcrum shaft so as to be pivotable, and the lock mechanism can fix the luggage placing member to the arc-shaped rail.

[0010] Further, the arm provided above and below the luggage placing member is pivotally fixed to a horizontal plate provided above and below the elevating member so that the luggage placing member can be pivotally attached to the elevating member. The lock mechanism is formed by a plurality of holes provided in the horizontal plate so as to be arranged on the same circumference centering on the pivot portion of the arm, and a lock pin attached to the arm so as to be engaged and disengaged from the hole. Structure.

Further, the temporary structure is formed by a frame scaffold assembled by using a building frame and a scaffold plate, and a guide rail is fixed to a vertical column of the building frame using a clamp, and the luggage placing member is provided. However, when it is rotated so as to approach the frame scaffold, a part thereof is in a fall prevention state facing the scaffold plate of the frame scaffold.

In addition, a drop prevention mechanism is provided at the upper end of the lifting member to be connected to the wire of the lifting means, and the drop prevention mechanism is pivotally mounted on the upper end of the lifting member so that the hanging hanger can swing up and down. At the leading end of the hanging hanger, a connecting portion with the lifting means, and at the rear end, the hanging hanger is loosely fitted to the guide rail in a horizontal state, and acts to bite into the guide rail when the hanging hanger is tilted. Can be formed by biasing the elasticity of the hanging hanger in the direction of tilting.

2 can be pivoted in the vertical direction, and a connecting rail 73 connected to the lifting means 14 at the tip of the hanging hanger 72 and a guide rail in a horizontal state of the hanging hanger 72 on a plate 74 fixed to the rear end as shown in FIG. An outer fitting portion 75 is provided on the guide rail 12 that is loosely fitted to the guide rail 12 and acts to bite into the guide rail 12 when the hanging hanger 72 is tilted. The tilting elasticity of the hanging hanger 72 in the direction in which the tip is lowered by a spring 76 is provided. The horizontal maintaining plate 77 of the hanging hanger 72 is fixed to the upper end of the lifting member 13.

The drop prevention mechanism 69 can be used as it is in the lifting device 11 of the first embodiment.

The lifting device according to the second embodiment has the above-described configuration, and the operation of assembling and disassembling the lifting device 11 is basically the same as that of the first embodiment. However, when the lifting device 11 is moved up and down by activation of the lifting means 14, the connecting portion 73 provided at the tip of the hanging hanger 72 is lifted. The state is maintained, and the outer fitting portion 7
5 does not bite into the guide rail 12, so that the lifting device 11 smoothly moves up and down along the guide rail 12.

If the wire 32 is cut while the lifting device 11 is being lifted, no lifting force is applied to the tip of the hanging hanger 72, and the hanging hanger 72 is inclined by the elasticity of the spring 76 as shown in FIG. Outer fitting part 75 at rear end
Acts so as to bite into the guide rail 12, and the lifting device 11 stops.

In order to take in the material A from the luggage placing member 17, the luggage placing member 17 is rotated with the lock pin 67 of the lock mechanism 64 pulled out and pulled out of the hole 65. A part is taken into the frame scaffold 1, the lock pin 67 of the lock mechanism 64 is returned to the lock position, and the luggage placing member 17 is fixed to the elevating member 13.

The luggage placing member 17 with the material A lowered is locked by pulling the lock pin 67 of the lock mechanism 64 in the releasing direction so as to be positioned outside the framework scaffold 1 and locked. Guide rail 1 by starting 14
2 may be moved up and down.
