Abstract
A scaffolding system is defined by a first primary platform connected to a first cantilevered ladder, a second primary platform connected to a second cantilevered ladder, and a work platform extending between and connected to the first and second primary platforms.
Claims11
A scaffolding system, comprising:
- a first ladder having a stepped unit defined by first and second stepped unit side rails each having bottom ends, plural steps interconnecting the first and second stepped unit side rails, and a top plate interconnecting the first and second stepped unit side rails at an upper end thereof, and a support unit defined by first and second support unit side rails, wherein each of the first and second support unit side rails is attached to a respective stepped unit side rail at a bracket located intermediate along the respective first and second stepped unit side rails between the bottom ends and the upper ends to define a first cantilevered ladder, and a first ladder platform having first and second attachment members interconnected with fasteners to the respective first and second stepped unit side rails of the first ladder such that the first ladder platform is above the top plate of the first ladder;
- a second ladder having a stepped unit defined by first and second stepped unit side rails each having bottom ends, plural steps interconnecting the first and second stepped unit side rails, and a top plate interconnecting the first and second stepped unit side rails at an upper end thereof, and a support unit defined by first and second support unit side rails, wherein each of the first and second support unit side rails is attached to a respective stepped unit side rail at a bracket located intermediate along the respective first and second stepped unit side rails between the bottom ends and the upper ends to define a second cantilevered ladder, and a second ladder platform having first and second attachment members interconnected with fasteners to the respective first and second stepped unit side rails of the second ladder such that the first ladder platform is above the top plate of the second ladder;
- a work platform connected to each of the first and second ladder platforms.
A scaffolding system, comprising:
- a first ladder in a first position and defined by first and second stepped unit side rails, a top plate interconnecting the first and second stepped unit side rails at an upper end thereof, a support unit defined by first and second support unit side rails, and a primary platform connected to each of the first and second stepped unit side rails with fasteners that extend through the primary platform and the respective first and second stepped unit side rails and such that the primary platform extends over the top plate;
- a second ladder in a second position and defined by first and second stepped unit side rails each having bottom ends, plural steps interconnecting the first and second stepped unit side rails, a top plate interconnecting the first and second stepped unit side rails at an upper end thereof, a support unit defined by first and second support unit side rails, and a primary platform connected to each of the first and second stepped unit side rails with fasteners that extend through the primary platform and the respective first and second stepped unit side rails and such that the primary platform extends over the top plate;
- and
- a scaffolding platform attached to each of the primary platforms of the first and second ladders and extending between the first and second ladders.

- a second ladder having a stepped unit defined by first and second stepped unit side rails each having bottom ends, plural steps interconnecting the first and second stepped unit side rails, and a top plate interconnecting the first and second stepped unit side rails at an upper end thereof, and a support unit defined by first and second support unit side rails, wherein each of the first and second support unit side rails is attached to a respective stepped unit side rail, and a second ladder platform having opposed first and second side plates, each of the opposed first and second plates including a coupler defined by a V-shaped extension extending downwardly from the respective opposed first and second side plates, each V-shaped extension having a bore, and each of the first and second stepped unit side rails including a cooperatively shaped V-shaped notch, each V-shaped notch having a bore, and wherein when each of the V-shaped extensions is engaged with a respective one of the V-shaped notches when the extensions are received in the notches and a fastener is extended through the bores in the V-shaped extensions and the V-shaped notches;
- and
- a work platform connected to each of the first and second ladder platforms.
