Claim:
A carriage assembly comprising: a scaffold; a carriage frame for supporting the scaffold, the carriage frame consisting of four tubular frame members, wherein the tubular frame members are arranged and connected at their terminal ends such that they form a rectangular frame, wherein each end of each frame member has an open port for receiving a jack body, such that each corner of the rectangular frame consists of a first port oriented in a first direction and a second port oriented in a second direction that is substantially perpendicular to the first direction, wherein the first port and the second port have a substantially similar configuration; a caster; and a first jack body coupled to said carriage frame and said caster, said first jack body having a longitudinal axis, said first jack body configured to selectively move said caster with respect to said carriage frame along the longitudinal axis to enable a height of said carriage assembly to be selectively adjusted, wherein said first jack body is interchangeably coupleable to said first port and to said second port to enable a length of said carriage assembly and a width of said carriage assembly, respectively, to be selectively adjusted without requiring the scaffold to be disassembled from the carriage frame.
