Multiple Self-Retracting Lanyard, Single Brake Fall Protection Systems and Methods

Abstract:

Fall protection systems and methods for a load in an elevated position include at least two self-retracting lanyards configured to be removably coupled to the load. The at least two self-retracting lanyards are associated with a single braking system that arrests movement of the at least two self-retracting lanyards when the single braking system mechanically senses that a speed of any one of the at least two self-retracting lanyards has increased to a threshold brake speed that indicates the load is falling from the elevated position.
