A cart assembly includes a frame that has an axle extending across a lower end thereof. Handles are included that have slotted and telescoping upper and lower sections. A transport platform is pivotally connected to each handle base and the axle, and folds against the handles. The platform has an arm wrapped about a major axle circumference. The arm has a gap formed therein. A horizontal support bar is positioned at an assembly top end, and is vertically raised and lowered for adjusting an assembly height. Horizontal members are included that form a part of the frame and extend between the handles below the horizontal support bar. Each horizontal member has hooks rotatably mounted therearound and further is slidably displaced along longitudinal lengths of the horizontal members. Wheels are rotatably mounted about opposed axle ends. A mechanism is included for prohibiting the platform from biasing downwardly from a raised position.
