Safety device for parachute activation in lifting systems. Safety device (100, 200) for activating at least one first parachute (150) of a lifting system comprising a car or a counterweight, at least one first guide (50) configured to guide the car or the counterweight and a car or counterweight positioning and actuation system comprising a position sensor configured to detect a dangerous situation, for example, an overspeed value of the car or counterweight and control electronics configured to disconnect an electromagnet (140), the first parachute (150) is configured to imprison the first guide (50) of the car or of the counterweight during a wedging position, blocking the downward movement of the car or of the counterweight, where the safety device (100,200) comprises a traction element (110) parallel to the first guide (50) of the cabin or counterweight and a mechanism (120) guided by the traction element (110), where the entrapment of the traction element (110) by the mechanism (120) causes a relative upward displacement of the second structure (160) with respect to the first structure (130) in proportion to the downward displacement of the cabin or the counterweight, where said relative displacement acts on the first parachute (150).where the entrapment of the traction element (110) by the mechanism (120) causes a relative upward displacement of the second structure (160) with respect to the first structure (130) in proportion to the downward displacement of the cabin or the counterweight, where said relative displacement acts the first parachute (150).where the entrapment of the traction element (110) by the mechanism (120) causes a relative upward displacement of the second structure (160) with respect to the first structure (130) in proportion to the downward displacement of the cabin or the counterweight, where said relative displacement acts the first parachute (150).
