The wheeled structure includes two connected sub-assemblies articulated relative to each other, with conversion capability between three wheels in a single plane for ground running operations, two main wheels for conveyance like a hand truck, or two secondary wheels for transverse positioning when fitting panels vertically. The first sub-assembly accommodates main wheels and secondary wheels and the second sub-assembly accommodates a pole, telescopic column assembly and support frame for the plates. The two sub-assemblies are rigidly connected by an assembly unit having an arm ending in a caster. The sub-assemblies, depending on their relative angular position, fulfill various vertical and horizontal panel fitting functions. The pole is mobile vertically relative to the main wheels, to the rear thereof when running on the ground, and to the fore thereof when fitting the panels vertically by lifting action on the first sub-assembly.

1. Wheeled structure for handling and fitting panels or plates comprising a pole with a set of telescopic columns extending under action of a winch, an upper column accommodating a frame made from shaped elements for the accommodation, holding and presentation of plates and panels for fitting, the frame being pivotably mounted relative to a support structure associated with said frame so that the plates or panels can be presented vertically or horizontally and engaging with said upper column, first and second connected sub-assemblies articulated one relative to the other, and wherein said wheeled structure has conversion capability so that it can be handled by an operator on three wheels in a single plane for ground running operations, on two main wheels for conveyance, or from two secondary wheels so that a transverse position can be adjusted when fitting panels or plates vertically, the first sub-assembly being arranged to accommodate the main wheels and the secondary wheels and the second sub-assembly to accommodate the pole with the set of telescopic columns and the support frame for the plates or panels for fitting, the first and second sub-assemblies being rigidly connected by an assembly unit starting from which an arm is placed including a caster, the sub-assemblies depending on a relative angular position thereof, are used to fulfil various vertical and horizontal panel and plate fitting functions, and the pole is mobile relative to said main wheels, to the rear thereof when running on the ground, and to the fore of said main wheels when fitting the panels or plates vertically by lifting action on the first sub-assembly. 2. Wheeled structure as claimed in claim 1, wherein the first sub-assembly comprises a frame made with two spaced apart and parallel tubular spars, an upper end of is the spars being shaped and connected to form a handle that can be gripped by the operator, a lower end of said spars being rigidly connected to an axle, ends of the axle bearing the main wheels said first sub-assembly includes in a front part thereof an added section welded to the axle forming a support platform for the plate or panel, and said first sub-assembly includes at the front the secondary wheels placed crosswise relative to direction of movement of the main wheels. 3. Wheeled structure as claimed in claim 2, wherein the secondary wheels are smaller in diameter than the main wheels, and are mounted to the front of the wheeled structure, starting from shaped spars secured to the axle, and the secondary wheels are located in a plane substantially above a main wheel ground support and running plane. 4. Wheeled structure as claimed in claim 2, wherein the assembly unit connecting the first and the second sub-assemblies includes a stirrup, the stirrup is arranged to enable the first sub-assembly to articulate relative to the second sub-assembly via a pivot pin passing through the stirrup, the pivot pin is provided and placed in an angled part of the frame between the tubular spars and the grip handle-forming upper end thereof, said stirrup is secured in position using anchoring and locking means enabling a secure assembly relative to the pole, and the anchoring and locking means provide fixed height positioning of the first sub-assembly relative to the second sub-assembly. 5. Wheeled structure as claimed in claim 1, wherein the pole is hollow internally and accommodates the set of telescopic columns deployed relative to one another by a mechanism including the winch, the winch comprising a chain system winch, with one or more strands, and the winch is itself activated by a power-driven means. 6. Wheeled structure as claimed in claim 4, wherein the unit forming a stirrup has spaced apart and parallel flanges provided with oblong apertures, the pole is arranged externally between said flanges with a clevis which enables the arm to be positioned by a hinge pin, said arm having the caster at an end of the arm, and the arm has lugs that slide in the apertures of the flanges.
