A fall protection safety device including a braking mechanism comprises a first component, a second component configured and arranged to move relative to the first component, and at least one magnet operatively connected to one of the components and another of the components being at least partially made of a non-ferromagnetic and electrically conductive material.The at least one magnet and the non-ferromagnetic and electrically conductive material create an electromagnetic field force when the second component moves at a rate greater than a predetermined rate relative to the first component.The first component is a housing and the second component includes a drum rotatably operatively connected to the housing, further comprising a lifeline having an intermediate portion interconnecting a first end and a second end, the first end being operatively connected to the drum, the intermediate portion being wound about the drum, and the second end extending through the housing. |
