<p>The invention relates to an automatic climbing device for lifting structures and roofing. The inventive device comprises heads (1 and 2) which can be joined to a support (4) with one blocking element (9) per head, said blocking element being blocked automatically and pressed continuously under the action of a counterweight (7) or spring (10). According to the invention, the climbing heads (1 and 2) are configured such that they can be adapted to the dimensions of posts or supports (4) of any size, having a T- or I-shaped cross-section, said heads being fixed to the branches of the posts using mobile clamps (11). The above-mentioned blocking element (9) can take the form of a double roller which is blocked on the support track (4) and which is pressed by the counterweight (7) which is in turn fixed to the head by a central shaft (8) that is provided with springs (10) which are fixed such as to produce the necessary blocking and return mechanisms for the operation of the device.</p> |
