Abstract
A portable truss cable roofing safety apparatus and method to assist users while working on the roof of a building structure. The portable apparatus provides a pair of similar opposing vertical trusses mounted adjacent opposite sides of the building structure. At least one brace is adaptable for securing each of the pair of vertical trusses to the building structure. A cable is connected to and extends between the pair of vertical trusses. An automatic belay device slidably is connected to the cable and has a safety line connected thereto, wherein the automatic belay device adjusts a length of the safety line to assist the user when the user is connected to the safety line.
Claims15
A portable truss cable roofing safety apparatus to assist a user working on a building structure having a roof, the apparatus comprising:
- a pair of opposing vertical trusses mounted adjacent and spaced from opposite sides of the building structure;
- at least one brace adaptably secured to the roof with fasteners for adjustably securing each one of the pair of opposing vertical trusses to the building structure;
- a cable connected to and extending between the pair of opposing vertical trusses;
- and
- an automatic belay device slidably connected to the cable and having a safety line connected thereto, wherein the automatic belay device is configured to adjust a length of the safety line when the user is connected with the safety line;
- the at least one brace having at least one horizontal brace adjustably connected to each one of the pair of opposing vertical trusses and pivotally connected to the roof of the building structure;
- and
- a cylindrical position ring that overlaps and receives each one of the pair of opposing vertical trusses to slidably adjust the cylindrical position ring on each one of the pair of opposing vertical trusses and pivotally connect the cylindrical position ring to the at least one horizontal brace to adjustably position the at least one horizontal brace on each one of the pair of opposing vertical trusses.
A portable truss cable roofing safety method for assisting a user working on a roof of a building structure, the method comprising steps of:
- assembling at least two vertical trusses adjacent to and spaced from opposite sides of the building structure, wherein heights of the at least two vertical trusses are selected so that the at least two vertical trusses extend above the roof of the building structure;
- adjustably mounting at least one brace to each of the at least two vertical trusses, the roof of the building structure, and a supporting surface;
- suspending a cable over the roof of the building structure, wherein the cable is connected to each of the at least two vertical trusses;
- and
- slidably mounting an automatic belay device on the cable, wherein the automatic belay device adjusts a safety line to remain taut to assist the user working on the roof of the building structure;
- and
- adjusting a position of the at least one brace on each of the at least two vertical trusses by sliding a cylindrical position ring over each of the at least two vertical trusses and pivotally connect the cylindrical position ring to the at least one brace.
