A scaffold device comprising a wheeled frame means including
a front axle assemble and a rear axle assembly which are pivotally
interconnected about a horizontal axis whereby either of the axle
assemblies may be pivoted or rotated relative to the other. A
first post is pivotally connected at its lower end to the front
axle assembly and extends upwardly therefrom. A telescoping sup-
port is pivotally connected at its lower end to the front axle
assembly and extend upwardly to a pivotal connection with the
first post to permit the first post to be vertically positioned
regardless of the attitude of the front axle assembly A second
post is pivotally secured at its lower end to the rear axle assem-
bly and extends upwardly therefrom. A telescoping support is
pivotally connected at its lower end to the rear axle assembly and
is pivotally connected at its upper end to the second post adjacent
the upper end thereof to permit the second post to be vertically
positioned regardless of the attitude of the rear axle assembly
A platform is slidably mounted on the first and second posts and
