る。Next, a description will be given of the work of transporting the lattice-shaped rebar 6 using the lifting and transporting apparatus having the above-described configuration. First, the horizontal frame 3 is placed on the upper part of the grid-shaped reinforcing bar 6 placed in a stacked state at the standby position.
Is moved, and the hoist 2 is driven to lower the horizontal frame, so that the tip of the suspending tool 5 enters between the lattices of the uppermost lattice-shaped reinforcing bar 6. In this state, the claw portion 19 inclined upward is shifted to one side between the lattices, and when the motor 7 is driven forward by one stroke, the claw portion 19 at the lowermost end is raised, and the claw portion 19 at the inclined upper side is moved upward. The intersecting reinforcing bar 6a is lifted while being supported. This state occurs at four places at a time, and the uppermost grid-like reinforcing bar 6 is held at the lower part of the horizontal frame 3 while maintaining a horizontal state.

されることになる。When the claw portion 19 supporting the first lattice-shaped reinforcing bar 6 reaches the uppermost position in the horizontal state, the motor 7 is stopped.
This time, by raising the horizontal frame 3, a plurality of lattice-shaped reinforcing bars 6 are held in a stacked state below the horizontal frame 3 as shown in FIG. 1.

し換えられることになる。Next, when the crane 1 is run and reaches a predetermined position on the slab surface, the horizontal frame 3 is lowered to make the lowermost grid-like reinforcing bar 6 face the predetermined position on the slab surface, and then the descent is stopped. If the motor 7 is driven in reverse by one stroke in this state, the horizontal lower claw portion 19 located at the lowermost position moves to the vertical position side, and as a result, the reinforcing bar 6a is detached from the lower claw portion 19 and the lowermost position. Only the lattice-shaped reinforcing bar 6 is transferred to the slab surface.

ち上げ作業及び分配作業が繰り返される。After the completion of the installation work, the horizontal frame 3 is raised again, moved to another place, and the same distribution installation work as described above is performed. This work is repeated for the number of the grid-shaped reinforcing bars 6 held, and after all of the work is distributed, the work is moved to the standby position again, and the lifting work and the distribution work are repeated.
【００２２】なお、この格子状鉄筋６の吊り上げ枚数は

ば５〜１０箇所に順次格子状鉄筋６を分配できる。The number of lifting of the lattice-shaped reinforcing bars 6 is determined according to the length of the lifting tool 5 and the number of claws, but it is appropriate that the number is about 5 to 10 depending on the weight. The lattice reinforcing bar 6 can be sequentially distributed to 10 to 10 places.

The motor 7 and the first intermediate shaft 20 are rotationally transmitted through a plurality of spur gears 22, and the second intermediate shaft 21 is provided on both sides of the horizontal frame 3 at right angles to the intermediate shaft 20. The rotation is transmitted between both sides of the intermediate shaft 20 and the second intermediate shaft 21 via a bevel gear 23. Further, the rotation of the second intermediate shaft 21 and the upper gear 17 of the hanging tool 5 is transmitted via the sprockets 12 and 14 and the chain 16 as in the above-described embodiment.
