The shaft portion of the arm fixing bolt 10a that comes out is fitted into the arm fixing nut 10b and screwed.

  In this way, since the second auxiliary wheel 7 can be folded to the vertical portion 1a side of the main body 1, the second auxiliary wheel 7 is not obstructed. In addition, the structure in which the second auxiliary wheel 7 is temporarily folded is also effective when the heavy article transporter A is rotated in a horizontal and narrow space in the middle of ascending and descending. Furthermore, when the second auxiliary wheel 7 is used again, it may be attached in the reverse order.

  Further, since the loading platform 2 can be attached to the main body 1, when the heavy load carrier A is carried on a car and carried or when it is stored without being used, it is not necessary to take up extra space if the loading platform 2 is removed. This is compact and space-saving. Further, the casters 11a and 11b are convenient because they can be replaced when they are all worn or worn. Further, when all the auxiliary wheels 4a and 7a are worn or worn, they can be exchanged for convenience.

  Moreover, since it was decided to support a part of the weight of this heavy goods carrier A on the inclined conveyance path, if it is one inclined conveyance path, the number of the towers C may be one, and installation and removal of the tower C The number of man-hours and time involved in the operation can be reduced. For example, in transporting a rental transformer, the power outage time can be greatly shortened.

  In the above-described embodiment, the main body 1 is formed by an L-shaped member made of an angle material. However, the main body 1 is not limited to the angle material, and may be a square material or a round material. . Moreover, although the chain block 23 is used as power for carrying heavy objects, the power is not limited to the chain block, and any power can be used as long as it can be used in the heavy goods carrier A.

  Furthermore, although the control panel 24 is spread when moving along the transport path, the use of the control panel is not limited to the control panel, and other plate bodies may be used.
