Patent number: 10722738Abstract: An improved safety system in accordance with the disclosed and claimed concept connects directly with the rail and advantageously provides both a fall resistance apparatus as well as a fall protection apparatus. The fall resistance apparatus provides a support that is movably situated on the rail and that can be manually grasped by the worker during the maintenance operation and which provides physical support in all directions to the worker. The fall resistance apparatus thus resists the likelihood that a fall will occur. In the unlikely event of a fall, the fall protection apparatus connects the worker directly to the rail and supports the worker from the rail at a location spaced above the floor, thus protecting the worker from injury in the event of a fall.Type: GrantFiled: July 18, 2018Date of Patent: July 28, 2020Assignee: Westinghouse Electric Company LLCInventor: Thomas E.
