After being rotated downward about the mounting portion, the stop means stops at the set position and the blow-up preventing member is also set at the set position in conjunction with the gantry body.
In this state, when a blowing force due to wind or the like acts on the gantry main body, the gantry main body tends to rotate upward. However, the rotation preventing member is restrained by the holding means to prevent the gantry main body from rotating. Further, when the winding member of the winding mechanism is unwound from the state where the gantry main body is at the set position, first, the blow-up preventing member is detached from the gantry main body by the releasing means, and then the gantry main body is moved to the temporary member. After rotating the winding member upward in the center of the mounting portion, the gantry main body is brought to the folding position in a state where the winding member is completely unwound, and the blow-up preventing member is brought to the folding position in conjunction with the gantry main body.

置となる。Therefore, when the winding member of the unwinding mechanism is unwound from the state where the gantry body is in the folded position,
After the gantry main body rotates downward around the mounting portion with the temporary member by its own weight, it is stopped by the stopping means and arranged at the set position, and the blow-up prevention member also interlocks with the gantry main body by its own weight. After rotating downward about the attachment portion with the temporary member, it is arranged at the set position. In this state, when a blowing force due to wind or the like acts on the gantry main body, the gantry main body tends to rotate upward. However, the gantry main body comes into contact with the blow-up preventing material by the stopper member, thereby preventing the gantry main body from rotating. When the winding member of the winding mechanism is unwound from the state where the gantry main body is at the set position, first, the loosened winding member comes into contact with the abutting member, and the blow-up preventing material is removed. Then, after the gantry body rotates upward centering on the attachment portion with the temporary member, the gantry body is in the folded position with the winding member fully unwound, and the blow-up prevention material is also In conjunction with this, it is rotated upward about the attachment portion with the temporary member to the folding position.

うになっている。Next, the operation of the loading gantry 1 from the folded state shown in FIG. 4 to the set state shown in FIG. 2 will be described. First, when the operation lever 23 of the electric chain block 21 shown in FIG. 4 is operated, the rewinding of the chain 22 is started by the internal drive motor 24. Then, as the chain 22 is rewound, the gantry body 31 moves the pin 36 in the downward direction A ′ by its own weight.
While the blow-up preventing member 41 also contacts the stopper member 37 of the gantry main body 31 by its own weight, and moves in conjunction with the gantry main body 31 in the downward direction B ′.
Rotate around 5. Then, the rewinding of the chain 22 proceeds, and the chain 38b (and 38a) shown in FIG. 2 is taut, and the gantry body 31 is arranged at the set position. At this time, the blow-up preventing member 41 that has been linked to the gantry main body 31 is also arranged while being held by the holding plate 37b of the gantry main body 31. The rewinding of the chain 22 is stopped by a limit switch (not shown) in a state where the chain 22 is sufficiently relaxed so as not to disturb the work.

質などの変更が可能である。The present invention is not limited to the above embodiment. For example, as a temporary member to attach the loading gantry,
In place of the framework scaffold, a mounting plate is provided on the skeleton,
The gantry main body and the blow-up preventing member can be rotatably provided directly without using the fixed frame and the clamp. Also, the interlocking of the blow-up prevention member with the gantry main body can be performed by using a movable hinge or the like in addition to performing the contact between the both. Further, the winding mechanism and the winding member are not limited to the electric chain block as long as the gantry body can be rotated up and down. Also,
Although the embodiment has been described as having the blow-up preventing member, it goes without saying that the blow-up preventing member is not necessarily required. For example, if the gantry body has its own weight of at least 5 kg per square meter, it will not be blown up by the wind. Further, in the other embodiments, the loading gantry is provided with rails to move vertically, but it is needless to say that the gantry can be moved horizontally to move the position of the loading gantry on the same floor. . Further, the stop member of the gantry main body, the stopper portion and the abutting member serving as the holding / releasing means for the gantry main body with respect to the gantry main body, and the drive mechanism for traveling the rails, etc. are also structured and operated within the scope of the gist. The shape and material can be changed.

る。According to the present invention, since it can be folded so as not to interfere with other operations, the degree of freedom of its arrangement can be increased. Therefore, for example, by installing a plurality of loading gantry at positions overlapping in a plane, it is possible to save space, and a vehicle or a crane for transporting materials can carry in / out materials at the same position. Furthermore, if the vehicle is equipped with a drive mechanism so that it can travel in the up and down direction, when the loading of materials is concentrated on a certain floor, it can be concentrated and arranged on a plurality of loading gantry there, so that the Can be loaded and unloaded. In addition, since one unit can also serve as a loading gantry on a plurality of floors, it is not necessary to provide the gantry on each floor as in the case of a fixed-type loading gantry. In addition, if the vehicle is provided with a drive mechanism so that it can travel in the horizontal direction, the positions of loading and unloading of materials and equipment can be changed on the same floor in accordance with the progress of work. Further, since the loading gantry can be set in the set state or the folded state by simply operating the switch, the work is simple and no dangerous work is required. This is also true for rail running.
