A utility cart operable to provide objects thereon to a user that is in a position that is generally above the cart such that a portion of the cart to extended to be proximate the user. The cart further includes a frame that includes a base member having four legs that support a platform. The platform includes several recessed compartments that house lifting members. The lifting members are operably coupled to an upper tray. The platform further has disposed therein a plurality of gears that are operably coupled to drive rods, which operate the lifting members. A handle acts as the controller wherein the user can provide rotational force to the handle, which is transferred to the gears and subsequently the drive rods creating the movement in the lifting members which transitions the position of the upper tray.
