1. A land based drilling rig comprising:
- a first and second lower box, the lower boxes positioned generally parallel and spaced apart from each other;
a drill rig floor coupled to the first lower box by a first strut, the first lower box and first strut defining a first substructure, the drill rig floor coupled to the second lower box by a second strut, the second lower box and second strut defining a second substructure, the struts hingedly coupled to the drill rig floor and hingedly coupled to the corresponding lower box such that the drill rig floor pivots between an upright and a lowered position, the drill rig floor including a V-door, the V-door oriented perpendicularly to a long axis of one of the substructures;
a first and second hydraulic cylinder, the first and second hydraulic cylinders connected to the drill rig floor and the lower boxes; and
diagonals coupled between the drill rig floor and first and second substructures.

Abstract
The drilling rig includes a first substructure and a second substructure. The second substructure is positioned generally parallel to and spaced apart from the first substructure and generally the same height as the first substructure. The drilling rig further includes a drill floor coupled to the first and second substructures, where the drill floor positioned substantially at the top of the first and second substructures.

10. A method comprising:
-
positioning a first and second lower box generally parallel and spaced apart from each other; coupling a drill rig floor to the first lower box by a first strut, the first lower box and first strut defining a first substructure, the drill rig floor including a V-door, the V-door oriented perpendicularly to a long axis of one of the substructures; coupling the drill rig floor to the second lower box by a second strut, the second lower box and second strut defining a second substructure, the struts hingedly coupled to the drill rig floor and hingedly coupled to the corresponding lower box; pivoting the drill rig floor between an upright and a lowered position using a first and second hydraulic cylinders, the first and second hydraulic cylinders connected to the lower boxes; pivoting the drill rig floor between the lowered position and the upright position using the first and second hydraulic cylinders; and coupling diagonals between the drill rig floor and first and second substructures. - View Dependent Claims (11, 12, 13, 14, 15)
