Abstract
Methods for erecting a drilling structure on a drilling rig include hoisting a first end of a column racker with a support carried by a mast on the drilling rig while the column racker is in a first position, and advancing a second end of a column racker along a solid surface toward the mast while simultaneously hoisting the first end of the column racker to move the column racker toward a second position that is closer to vertical than the first position. Other methods include raising a first end of a column racker with a ground-based, powered lift structure, and introducing the first end of the column racker to the rig floor while supporting the weight of the column racker with the ground-based, powered lift structure.
