Abstract
An adjustable drilling rig is provided for drilling and installation of foundational micropile matrices in difficult to access locations. A support frame of separately adjustable legs define a perimeter of the rig and drilling area. A translational frame of arms and a crossbar is selectively mounted to the support frame for easy transport and assembly at remote work sites. The crossbar is selectively slidable along the arms in a Y-axis direction. A crossbar bushing is selectively slidable along the crossbar in an X-axis direction. A mast is slidably attached to and movable with the crossbar. Various adjusters are included and are independently and selectively activated to move the crossbar, and therefore mast and attached drill head, translationally along the X- and Y-axes, optionally Z-axis, and rotationally about the X- and Y-axes to achieve five degrees of freedom in five planes for drilling at any angle within the drilling area.
