(54)	Device for the lifting and transportation of blocks of hollow pieces in sites with limited access space

(57) It comprises a plurality of lifting and transportation elements (30), constituted by two oblong, flexible elements (1, 2) facing each other and adapted to be introduced via their free end into the horizontal hollow channel of the lower piece of a block (10), each flexible, oblong element being movable longitudinally and curved by a supporter-curver device (3, 4) and being provided with an introduction and extraction device (5, 6) to force it to move through the supporter-curver device (3, 4). The assembly is supported in a base structure (7, 8) provided with vertical displacement movements (v) and horizontal displacement movements (h). The free end of the elements (13) supports the vertical bending stress produced by the weight of the block on lifting it.
