Even if disassembled, the weight of each member is large, 100 kg
Because of the above, separate lifting equipment and transport equipment are required for disassembly and assembly. In addition, the lifting of the suspended load is often performed by moving the column up and down by a hand-wound winch without using a hydraulic jack. Therefore, there is a risk that the height of the pair of columns does not match, and the column tilts left and right. . Furthermore, since a hand catch pallet is attached to the outside of the support,
A large work space is required, and when the distance between the switchboard and the wall is small (for example, 1 m or less), it cannot be used.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and to provide a heavy-weight moving apparatus which can be easily assembled, disassembled and transported, and can move heavy objects accurately.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, according to the present invention, there is provided a pair of columns which can be extended and contracted as an upper column member and a lower column member as a slide connection structure, and are connected between upper ends of the pair of columns.
