1. A land-based drilling rig comprising:

  • a plurality of columns, the plurality of columns being either polyhedrons having a square base or generally cylindrical, wherein each of the plurality of columns includes an upper end and a lower end, and wherein the lower end of each column includes a hydraulic walker having a retracted position and an extended position;

    a drill rig floor, the drill rig floor having an upper surface and a lower surface, wherein the upper end of each column is pinned or welded directly to the lower surface of the drill rig floor, and wherein the retracted position of each hydraulic walker is beneath the drill rig floor;

    at least one equipment support cantilever, wherein the equipment support cantilever is hingedly or fixedly coupled to at least one of the drill rig floor or a column, and wherein the equipment support cantilever is adapted to support one or more pieces of drilling rig equipment mechanically coupled thereto; and

    a mast, the mast mechanically coupled to the upper surface of the drill rig floor;

    wherein the weight of the mast and drill rig floor is supported by the columns regardless of whether the hydraulic walkers are in the retracted position or the extended position; and

    wherein the distance between two adjacent columns is A and the distance between two other adjacent columns is A′

    , wherein A and A′

    are each greater than the diameter of a wellhead and wherein the land-based drilling rig is adapted to be moved away from a wellsite such that the wellhead passes between any pairing of columns forming distances A or A′
