1. Self-climbing device for vertical and quasi-vertical concrete surfaces, of the type used in its construction, assembly, maintenance and/or repair to raise and lower various types of associated metal structures, characterized in that it comprises a main body (1), formed by a vertical metal structure, chosen from the group formed by lattice, tube, circular section, quasi-rectangular, equipped with a main beam (8), vertically disposed, and three self-motorized frames, said three self-motorized frames being an upper self-motorized frame (2a), an intermediate self-motorized frame (2b) and a lower self-motorized frame (2c), independent of each other and separately controllable, displaceable along the main beam (8) of the main body (1);
wherein the upper self-motorized frame (2a), the intermediate self-motorized frame (2b) and the lower self-motorized frame (2c), comprise means for horizontal displacement; and
wherein the means of horizontal displacement of the upper self-motorized frame (2a), the intermediate self-motorized frame (2b) and the lower self-motorized frame (2c), with respect to a working wall (3) comprise at least two linear actuators (17), actuated by motors (20), disposed on the sides of a sliding part (9), and traversing a displaceable chassis (10) through an opening (19), and connected at their ends with an anchoring chassis (11) by means of vertically positioned rotation axes (18).
