Abstract

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.

Description

[0001] This application is a divisional application of the application dated December 23, 2010, the application number is 201080056100.6, and the invention name is "falling protection safety device with braking mechanism". technical field [0002] The invention relates to a falling protection safety device with a braking mechanism. Background technique [0003] A fall protection safety device is well known in the art for fall safety protection equipment for use by workers when performing tasks where there is a risk of falling. [0004] One type of safety device commonly used is a track along the length of which a shuttle runs. The track is typically attached to a support structure in an area adjacent to the area where the worker performs the task, and the shuttle is typically attached to a harness worn by the worker. An energy absorber can also be used on this type of safety device to reduce the force transmitted to the worker. When a fall occurs, the shuttle locks to the ...
