Abstract
A fall restraint system protects a worker while inspecting and/or repairing a roof of a building. The restraint system includes a ladder that is positioned against the building. A fall restraint device is removably connected to the ladder and contacts the roof. A cable support structure is connected to the fall restraint device, and a cable is attached to it. The cable extends from the cable support structure toward the peak of the roof, and from the peak toward the ground. The cable is adapted to be connected to a harness that is worn by the worker. The worker then uses the cable to inspect/repair the roof.
Claims15
A restraint system for protection of a building roof worker, said restraint system comprising:
- a building ascension device;
- a portable fall restraint mechanism carried by said building ascension device;
- a cable support structure connected to an extension section of said portable fall restraint mechanism;
- and
- a cable having a first end connected to said cable support structure, said cable having both a first section for extending upwardly from said cable support structure and a second section for extending downwardly on an opposite side of a roof, said second section terminating in a tensioning element for biasing the cable taut;
- wherein at least one of the first and second sections of said cable is adapted to connect to a harness secured to the worker, and wherein the second section of the cable is positioned around at least one rune of said second ladder to bias said second ladder in a safe leaning position to enable the worker to ascend said second ladder safely.
A restraint system for protection of a building roof worker, said restraint system comprising:
- a building ascension device;
- a portable fall restraint mechanism carried by said building ascension device, said portable fall restraint mechanism comprising a ladder rung brace removably connected to a first ladder, said extension section pivotally connected to said ladder rung brace, and a resistant device pivotally connected to said extension section;
- a cable support structure connected to an extension section of said portable fall restraint mechanism;
- and
- a cable having a first end connected to said cable support structure, said cable having both a first section for extending upwardly from said cable support structure and a second section for extending downwardly on an opposite side of a roof, said second section terminating in a tensioning element for biasing the cable taut;
- wherein at least one of the first and second sections of said cable is adapted to connect to a harness secured to the worker, and wherein said resistant device includes at least two extension legs shaped in a "V" and extending from a pivotal connection of said extension section, and a frictionally securing resilient pad connected to each extension leg.
