ABSTRACT A mobile rolling support system for scaffolding used in building construction comprises a rolling support utilizing structural roof members as the principle supporting guide track for such rolling support. The rolling support comprises a leading outrigger having one or more motor driven travel wheels thereon as well as one or more idler travel wheels thereon, and a trailing outrigger having preferably, only a plurality of idler travel wheels thereon. These two outriggers, leading and trailing, are preferably connected by a frame comprising suitable beams including a pair of cross members. The near-side driven wheels (leading outrigger) and near side idler wheels (trailing outrigger) will ride on one structural roof member such as an I-beam, T-channel, C-purlin, or Z-purlin and the like. The far-side idler travel wheels on both the leading and trailing outriggers may ride on an adjacent structural roof member parallel to that first mentioned. These far-side, idler travel wheels are provided with force rollers which engage the underside of the said adjacent roof member so as to prevent the rolling support from lifting off of the roof members. Similar force rollers may be provided for the near-side travel wheels, both driven (leading) and idler (trailing), whereby the rolling support is, in effect, clamped to the purlins or other structural roof members on which it rides. A motor for driving the driven wheels is mounted an the rolling support and remote controls actuate it from any working position, including ground level. Support means extend from the frame to which scaffold structure may be attached.
