ABSTRACT:
A portable scaffold includes a base or chassis mounted on wheels for site-to-site towing or "man-handled" positioning at a job site. Rising rigidly from the chassis are two masts, spaced apart lengthwise of the chassis. A platform is vertically slidably carried by the mast for selective elevation and descent via power devices. Each mast may be increased in height by the addition thereto of a mast extension that functions as a prolongation of the basic mast. One of the power devices is alternately positionable to function as a temporary source of power for moving the scaffold through short distances. Strap elements are provided for temporarily bracing the masts from a structure being worked on by workmen on the platform.
