Not be used as work platforms when rungs are less than 11½ inches in length, unless each affected employee uses appropriate fall protection.Be specifically designed and constructed for use as ladder rungs.Integral (built-in) scaffold access frames must: Stair tower with stair rail, including toprail and midrail. Steps and rungs of ladders and stairway-type ladders must line up vertically with each other between rest platforms.Have slip-resistant treads on all steps and landings.Have a minimum step width of 16 inches, except for mobile scaffold stairway-type ladders, which shall have a minimum step width of 11½ inches, and.Have rest platforms at maximum vertical intervals of 12 feet,.Be positioned so that their bottom step is not more than 24 inches above the scaffold supporting level,.Have rest platforms provided at a maximum of 35-foot vertical intervals.Have minimum rung length of 11½ inches.Have uniform spacing between rungs of a maximum 16¾ inches.Be positioned so that their bottom rung is not more than 24 inches above the scaffold supporting level.Hook-on and attachable ladder rungs must:.Hook-on and attachable ladders must be specifically designed for use with the type of scaffold on which they are used.Portable, hook-on, and attachable ladders must be positioned so as not to tip the scaffold.
#Fabricated frame scaffold brackets portable#
Example of a frame scaffold with portable ladder for access. They also come in different widths depending on whether you are working in tight spaces or simply do not need a wide platform, which saves on board costs.Figure 6. Find out more about the difference between the major styles here.Įach style of frame scaffolding comes with frame variations such as walk-thru frames for masonry and stucco contractors and climbable ladder frames for building scaffold towers. The differences between these are largely regional and contractor preference since they mostly all function the same way.
The most common frame styles are Safeway, Waco, Bil-Jax and Snap On. There are different styles of frame scaffolding, each ones have different diameter tubs, pin sets, heights and locking mechanisms which keep them from integrating with one another. Frame Scaffolding Componentsįrame scaffolding components consists of the scaffold frame, cross brace, coupling pin, spring clip and some kind of a base whether it is a base plate, wheel, or leveling jack. It is the most commonly-used scaffolding in the construction industry. Frame scaffolding works well for working on straight walls with 90 degree turns and for building scaffold towers. The advantage of frame scaffolding is that is is much easier and faster to assemble than tube and clamp or ring lock/cup lock since the horizontal and vertical components are already fabricated and they frames are connected by cross braces, which snap into place. This is in contrast to tub and clamp and ring lock/cup lock type scaffolding where you have to assemble the vertical, horizontal and diagonal components. Frame scaffolding is a type of scaffolding in which pre-fabricated frames are connected and stacked on top of one another to create a scaffolding structure.
