Abstract
A mobile scaffold having a main frame with an elevated work station. Widener frames are detachably and pivotally connected to the main frame, forming a secure and integral part of the scaffold, the widener frames each having a vertically adjustable ground-engaging caster thereon to support the full weight of the scaffold. The widener frames are pivotal to an inward position narrowing the width of the scaffold to enable the scaffold to be rolled through narrow doors or aisles and pivotal outwardly to a position which widens the base and affords maximum stability for the scaffold when in use.
