A multi-purpose combined ladder/cart assembly capable of being converted into a plurality of ladder and cart configurations, including an extension ladder, a step ladder, a load-carrying cart, a pull cart, and a hand truck. The multi-purpose combined ladder/cart assembly includes a plurality of frame members that are pivotal with respect to each other and capable of being retained in variety of desired positions in order to easily configure the assembly in any of its various configurations. The travel characteristics and center of gravity of the cart configurations of the assembly are variably selectable, depending upon the load to be carried, by simply selecting various combinations of differently sized wheels to attach to the assembly.
