Abstract

The invention relates to a security system for operations in wind generators, applicable to wind generators with a hoisting point (2), comprising 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.
