ABSTRACT:
A moveable cart for transporting structures which are adapted for mounting upon a wall rail. The cart is constructed with a roller linkage assembly pivotally mounted to a wheeled frame and a deck mounted on the linkage assembly. The deck is engaged by the rollers of the linkage assembly so that the vertical position of the deck can be moved with regard to the wall rail, allowing a modular cell structure placed on the deck to be carried upward or downward. A rack driven gear locking assembly is rotatably mounted to the deck. The gear locking assembly is engaged by a rack assembly which is driven by the roller linkage assembly so that it rotates against the sides of the structure to hold the structure in a fixed position during the transportation and vertical positioning of the deck.
