[002] Safety cables of various types for preventing a worker working at elevations from falling to the ground have been developed in the past. More specifically, safety cables heretofore devised and utilized consist of a myriad of designs that have been developed for the fulfillment of numerous objectives and requirements.
While the devices heretofore fulfill their respective, particular objectives and requirements, they do not provide a fall arresting system that includes a retractable-cable reel (e.g., descent control device) and a safety cable having integrated therewith an accessory line as such there exists and need for a fall arresting system, which substantially departs from the prior art, and in doing so provides an apparatus primarily developed for the purpose of controlling descent and having an integrated safety cable and accessory line.
SUMMARY OF THE INVENTION
While the devices heretofore fulfill their respective, particular objectives and requirements, they do not provide a fall arresting system that includes a retractable-cable reel (e.g., descent control device) and a safety cable having integrated therewith an accessory line as such there exists and need for a fall arresting system, which substantially departs from the prior art, and in doing so provides an apparatus primarily developed for the purpose of controlling descent and having an integrated safety cable and accessory line.
SUMMARY OF THE INVENTION
[003] In view of the foregoing disadvantages inherent in the known types of safety cables now present in the prior art, the present invention provides a new fall arresting system wherein the same can be used for controlling descent and includes an integrated safety line and accessory line.
[004] In accordance with the present invention, an apparatus for fall arresting is provided, that increases safety on a work site by always keeping the safety line tight and away from a worker's feet.
[005] In accordance with the present invention, an apparatus for fall arresting is provided, that integrates a safety line and an accessory line, such as, an electrical power cable or a pneumatic hose, thereby reducing tripping hazards.
[006] In accordance with the present invention, an apparatus for fall arresting is provided, that reduces the risk of tools falling from elevations by integrating a safety line and a tool accessory line together such that the accessory line safely tethers the tool against falling.
[007] In general, in one aspect, a fall arresting system is provided. The fall arresting system includes a fall arresting cable that has a safety line with opposed first and second ends, an accessory line that extends substantially along the safety line between the opposed first and second ends of the safety line, and a sheath that envelops the safety line and the accessory line. The fall arresting system further includes a reel upon which the fall arrest cable is wound.
