A parallel link mechanism is configured with a connecting member that connects the other end, and a horizontal beam (14A) that protrudes toward the vertical transporter side is provided integrally with the connecting member that connects the boom tip and the other end of the link. The upper end of the vertical carrier is detachably connected to the beam via the pin (16), and the vertical carrier is disconnected from the horizontal beam by the pin (16), and It is connected by a hoisting rope having a length capable of tilting without interfering with.

[Action]

When removing the vertical transporter, fix the lower part of the vertical transporter on the trailer, remove the lower end of the connecting member from the side wall of the vertical transporter, and connect the vertical transporter and the horizontal beam with a lifting rope, The connection between the vertical carrier and the horizontal beam is released by removing the pin at the end of the horizontal beam.

Next, while moving the trailer or the unloader, the boom is lowered to tilt the vertical transporter suspended by the lifting rope, and the vertical transporter is placed on the trailer.

For mounting, reverse the procedure.

〔Example〕

The present invention will be described below with reference to an illustrated embodiment. In addition, the same reference numerals are given to the same or corresponding portions as in the conventional case.

As shown in FIG. 1, a rotary frame 2 is rotatably installed on a portal 1, and a base of a boom 3 is pivotally attached to the rotary frame 2 so that the boom 2 can be elevated. The boom 3 and the link 7 are pivotally connected to the rotary frame 2 at different positions, and the respective tips are pivotally connected to the connecting member 14 to form a parallel link mechanism. It is configured. The connecting member 14 has a horizontal beam 14 that horizontally protrudes toward the spiral vertical transporter 6 side.
A is formed. The tip of such a horizontal beam 14A is detachably connected to a bracket 15 at the center of the upper end of the spiral vertical conveyor 6 via a pin 16, whereby the spiral vertical conveyor 6 is hung on the beam 14A.
The side wall of the spiral vertical conveyor 6 and the connecting member 14 are fixed by the pin 17.

Further, a connecting piece 18 is provided at the upper end of the spiral vertical conveyor 6, and a connecting hole 19 is provided substantially at the center of the horizontal beam 14A, and one end of the lifting rope 20 connected to the connecting piece 18 is connected to the connecting hole 19. Connect to the inserted pin 21 (see FIG. 2).

The bellows 13 is attached to the boom 3 and the connecting member 14.

In the above configuration, the spiral vertical conveyor 6
When removing, the work is performed in the following procedure.

(i) As shown in FIG. 1, a trailer 23 having a tilting table 22 at the rear is arranged, the trailer 23 is supported by an outrigger 24, and the lower part of the spiral vertical conveyor 6 is fixed to the tilting table 22.
