Abstract: A security system for operations in wind generators, applicable to wind generators with a hoisting point (2), includes a cable (3) which is attached by one end to the element to be secured, normally a robotised unit (4), and by the other end to a counterweight (8), such that the cable (3) passes through a locking system (61) and a first pulley (6) which are attached to the hoisting point (2). The counterweight (8) can be installed on a pulley block (7) with at least two branches. The system ensures the integrity of the tower-nacelle assembly (1) and the robotised unit (4) in the event of the latter being detached.

Abstract: Robotized cleaning device used on ferromagnetic structures that includes two symmetrical cleaning arms and a caterpillar type tractor device that moves using magnetic soles over the bands of the caterpillar robot; and where the arms are jointly attached to the tractor device via a structural profile and include a cleaning roller, each of them operated by a reduction motor connected to the roller and nozzles.

Abstract: A washing system that can be installed on robotic devices for cleaning metal surfaces, includes a central support joined to a system of symmetrical arms that form a fork and are equipped with motor reducer systems connected to co-operating cleaning rollers, a pivoting central shaft that improves the stability of the robotic device during cleaning, against the risk of the wheels acting as a lever for the cleaning roller, as well as providing an effective arrangement for adjusting the pressure of the cleaning rollers, and a hinged cleaning arm intended to spray water and cleaning products, oriented to provide precision cleaning and offer improvements over systems known in the prior art.

Abstract: Robotized cleaning device used on ferromagnetic structures that includes two symmetrical cleaning arms (100, 200) and a caterpillar type tractor (300) device that moves using magnetic soles over the bands of said caterpillar robot; and where said arms (100, 200) are jointly attached to the tractor device (300) by means of a structural profile and are essentially comprised of a cleaning roller (1), each of them operated by a reduction motor (4) coupled to said roller (1) and a plurality of nozzles.
