A two-wheeled collapsible cart comprises a transverse bar having one wheel mounted on a caster fork beneath each opposite end thereof, a pair of symmetrically spaced bars pivotally mounted on the transverse bar providing therewith a collapsible platform and a pair of upstanding barrier bars. The bottom end of a lowermost section of an extendable leg of a camera tripod or unipod from which the non-slip cap has been removed is fitted with an element of a separable connector which engages a companion element mounted on a midportion of the transverse bar. Each spaced pivoted bar terminates in a downturned foot which cooperates with the wheels as a four point ground engaging support for the platform and the mounted upstanding tripod or unipod when the bars are in extended position. The handle of a conventional pan head which adjustably supports the camera on the tripod or unipod also serves as a manipulative handle for the cart when the platform, carrying the camera equipment, is tilted from the four point ground engaging position for transport on the two wheels. A strap is located for encircling the three tripod legs for retention in closed parallel position when the legs are retracted.
