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.

Abstract: An adjustable drilling rig is provided for drilling and installation of foundational micropile matrices in difficult to access locations. A platform and separately adjustable legs are provided to level the platform. Arms and a crossbar mount to the legs, and each includes a bushing slidably mounted and moveable there along. A mast is slidably attached to the crossbar bushing through a mounting plate. The mast carries a drill head to which a drill will be attached. Various adjusters are mounted to bushings, mounting plate and other components of the adjustable drilling rig and are independently and selectively activated to adjust the drill head translationally along the X-, Y- and Z-axes and rotationally about the X- and Y-axes to achieve five degrees of freedom in five planes. The entire adjustable drilling rig is provided in two frames for easy transport to remote work sites and may be assembled without complex tools.
