ABSTRACT:
A mobile scaffold has a carriage for traversing longitudinally a first track and a second track. The carriage is suspended from the first track. Lateral support for one side of the carriage is provided by the second track, and this track is spaced vertically from the first track. A parallel arm type crane has one end mounted to the carriage on a side that is opposite from the side adjacent the second track. Attached to the end of the crane extended outwardly from the carriage is an operator's platform. The crane can swing to position the platform both in elevation and in a direction lateral of the carriage. The carriage has a vertical drive shaft with a horizontal wheel mounted thereon for contacting the second track. Bearings fit about the vertical drive shaft and the end of the crane is attached to the bearings so as to swing about the drive shaft.
