Therefore, even when the length of the lifting arm 17 is short, a larger number of fire hoses 3 can be suspended. Therefore, since the protrusion length of the perpendicular | vertical direction with respect to the support | pillar 2 also becomes short also in this point, the compact elongate object raising / lowering apparatus 1 can be provided as a whole, and cost can be reduced.

  In the long object lifting / lowering apparatus 1 of the embodiment, each hanger 17b has a fire hose support portion 17b1 having a substantially linear shape that supports the fire hose 3, and the fire hose 3 is laterally connected to the fire hose support portion 17b1. It is formed in the shape of a hook having an opening 17b2 so that it can be hung, and the opening 17b2 is provided so as to be point-symmetric with respect to the longitudinal center of the lifting arm 17.

  For this reason, the fire hose 3 is suspended from the left and right sides of the third hook eyebolt 17e provided at the center of the lifting arm 17 on the plurality of hangers 17b of the lifting arm 17, so On the other hand, it becomes possible to suspend a plurality of fire hoses 3 in a well-balanced manner, and even a large number of fire hoses 3 that have become wet and heavy can be suspended and dried in a well-balanced manner.

  In the long object lifting apparatus 1 of the embodiment, the fire hose 3 is placed in the longitudinal direction of the lower arm 14 and the lifting arm 17 by a plurality of hangers 17 b orthogonal to the longitudinal direction of the lifting arm 17 at the upper part of the fire hose 3. On the other hand, the fire hose 3 is parallel to the longitudinal direction of the lower arm 14 and the lifting arm 17 by the lower arm body 14a and the opening / closing arm 14f of the lower arm 14 at the lower part of the fire hose 3. Hold it like so.

  Therefore, in the long object elevating device 1 according to the embodiment, a gap (space) is easily formed in the fire hose 3 suspended by the elevating arm 17, and the fire hose 3 can be dried more efficiently.

  In the description of the above embodiment, the locking means 14g is constituted by the latch plate 14g1, the latch portion exposed hole 14g2, the cannula fitting mounting plate 14g3, the cannula fitting 14g4, and the retaining ring portion 14g5. In the present invention, the invention is not limited to this, and a lock pin, a padlock, or the like is not particularly limited as long as the closed state of the lower arm main body 14a and the open / close arm 14f can be locked.
