Claim:
A climbing system for shuttering, scaffolding and loads in general, comprising: an upright adapted to be fixed to a wall or to move vertically in relation to the wall; a bracket arrangement to be fixed to the wall or to move vertically in relation to the wall with a movement relative to the upright, said bracket arrangement having mounted thereon a shuttering structure for casting sections of the wall; an upper head attached to the bracket arrangement and also solidly joined to a body portion of a hydraulic cylinder, the hydraulic cylinder including a rod; and a lower head attached to said rod of said hydraulic cylinder, each of said upper and said lower heads further comprising: a body with upper and lower wings defining therebetween guides that encircle the upright, each of the heads having a rocker configured to act on flanges or blocks distributed along the upright, the rocker being mounted on a transversal axis, against the action of a spring that permanently acts on the rocker in any of rocker's operating positions; a handle solidly joined to the transversal axis for rotating said axis to change the position of the rocker in relation to the upright, wherein the handle defines three operating positions for the rocker, including, (a) a position for raising the upright in which an upper face of the rocker is in a horizontal position and is adapted to push one of the flanges on the upright upwards to raise the upright, (b) a neutral position in which an inclined plane of the rocker is parallel to the upright and does not interact with the upright, and (c) a position for raising the bracket arrangement in which a lower face of the rocker is in a horizontal position and is adapted to rest on a flange on the upright to help raise the bracket arrangement; and a safety positioner limits the positions of the rocker, the safety positioner comprising: an inner disc that moves with a tilting movement of the rocker and that has a peripheral notch that defines a groove, which works with a spring positioner housed, depending on the operating position of the rocker, in one of three holes provided in an outer cover of the head, in such a way that the tilting movement of the rocker is limited when the spring positioner abuts against one of the edges of the groove in the inner disc and, specifically, (a) an upper hole into which the spring positioner is adapted to be inserted to define a position that limits the tilting movement of the rocker as the bracket arrangement is raised, (b) a lower hole into which the spring positioner is adapted to be inserted to define a position that limits the tilting movement of the rocker as the upright is raised, and (c) a central hole that defines a neutral position of the rocker, there being in a central area of the groove, a hole or recess that coincides in position with the central hole of the outer cover, into which the spring positioner is inserted, preventing the rocker from moving in either direction and thus securing the neutral position of the rocker.
