In the above configuration, when the crane (1) is raised on the running surface (4) by the trolley (2), as shown in FIG.
), the right locking plate (1α) is locked to the fixed hardware α9 by the closing operation of the locking member, and the left locking body αα and the fixed hardware 09 are opened. In this state, the chain (9
) is rotated clockwise, the chain (9) is fixed to the fixed hardware α9 of the running surface (4) at the locking body αO,
Also, since the front and rear sprockets (6) and (6r are attached to the running frame (2C)), as the chain (9) rotates, the left and right running frames (2C) move on the rails as shown in Figure 9 (1). (5) When the locking body αq on the left side overlaps the fixed hardware α9 above, the drive device 0η reaches the maximum forward position and stops.
As shown in 1, the left side locking body αO' and the fixed hardware 09 overlapping it are locked by the closing operation of the locking member 1, and at the same time the right side locking body 01 is locked by the opening operation of the locking member. to release from the fixed hardware α9. Therefore, in this state chain (9)
By rotating the wheel counterclockwise, the traveling frame (2C) will move upward in the same way as the above operation (cd) in the same figure).
, By repeating these operations in succession, the trolley (
2) can be raised together with the crane (1).

Next, when lowering the crane (1) together with the trolley (2), the reverse operation to the above-mentioned raising is performed as shown in FIG. That is, as shown in Figure (a), the locking plate αQ' on the left side is fixed to the fixed hardware (1υ), the locking plate αO on the right side is released, and the chain (9) is rotated clockwise. , Lower the traveling frame (2c) as shown in the same figure (b), and in this state, fix the right locking plate αO as shown in the same figure (C), and release the left side locking plate αO′. By reversing the chain (9) counterclockwise, the traveling frame (2c) is lowered as shown in FIG. 2(d), and these operations are repeated continuously.

As shown in Figure 8, the oil cylinder (to) has sequence valves (a) and (a)' in the hydraulic chambers (c) before and after the piston (c), and in the pipe line (c) communicating with 09'. As the piston +241 moves forward and backward, the pipe (c)
Part 1 - When the circulating pressure oil maintains the specified pressure, the sequence valve (c) is opened, and the hydraulic chamber (c), (
The pressure oil (c)' is now able to flow freely, so the oil cylinder (c) is expandable and retractable. Therefore, as the truck (2) moves up and down as shown in Fig. 9.10, the oil cylinder also freely expands and contracts, without causing any hindrance to the rotation of the chain (9).

(2) A dolly equipped with a crane is made to be able to run freely along a rail laid on a running surface, and sprockets that rotate around an axis perpendicular to the dolly are attached to the front and rear of the dolly in the running direction, and the front and rear sprockets A chain is wound around the chain, a locking body is connected to each of the left and right linear running parts of the chain, and one of the linear running parts is connected to a drive device provided on a dolly that rotates the chain forward and backward for a predetermined stroke, Fixing hardware is fixed to the running surface along the tensioning direction of the left and right linear running portions of the chain at a pitch equal to the distance that the left and right locking bodies are separated back and forth by forward and reverse rotation of the chain, and The trolley is provided with a locking member that moves together with the locking body and operates to lock or unlock the locking body and the fixed hardware, and the locking member is one of the left and right locking bodies. When locking, the other lock is released, and the locking and unlocking operations are performed alternately, and one end of the chain on the side where the drive device is not installed is connected to the locking body on the straight running part of the chain. An oil cylinder with the other end fixed to the traveling truck is arranged along the linear traveling section, and the oil cylinder locks the operation of the telescopic rod when the pressure rises above the specified hydraulic pressure, and locks the operation of the telescopic rod when the hydraulic pressure is specified. A crane moving device characterized in that the crane can be operated freely.
