A moving-scaffold device for painting a truss bridge, according to claim 1 or 2, in which a part or all parts of the inner three-dimensional frames have waterproof
Conventionally, it is very inefficient to build scaffolding for painting a truss bridge as the afore-mentioned, although public enterprises should cost time and money as little as possible
BRIEF SUMMARY OF THE INVENTIN It is an object of the invention to provide a moving-scaffold device with couplings for painting a truss bridge in the shortest time so as to minimize wood, labor costs and traffic jams, which will be a profitable business in the future
According to a first aspect of the invention, there is provided a moving-scaffold device for painting a truss bridge which has the scaffold and inner three-dimensional frames comprising a ceiling and both lateral surfaces having plural wheels at their feet to move at a low speed by driving powers, linked with the scaffold and outer three-dimensional frames comprising a roof and both lateral surfaces having plural wheels underneath the roof to move at a low speed by driving powers, with plural couplings
According to a second aspect of the invention, there is provided a moving-scaffold device for painting a truss bridge without wheels underneath the roof of the outer three-dimensional frames
According to a third aspect of the invention, there is provided a moving-scaffold device for painting a truss bridge with waterproof on a part or all parts of the inner three-dimensional frames
