Abstract
A drill rig includes a carrier platform and a drilling unit. The drilling unit includes a support frame mounted on the carrier platform, a slider frame mounted upon and surrounding the support frame, a drilling support mechanism mounted on the slider frame, a drill portion rotatable relative to drilling support mechanism, and a means for effecting rotation of the drill portion. The support frame assumes a substantially vertical position, and the slider frame is moved along the support frame to an operative position for effecting a drilling operation. The support frame comprises two main tower beams partially covered in High-Density Polyethylene plastic, and the slider frame comprises plates positioned on the top and bottom of the tower beams, with inside and outside joiner plates encasing the sides of the support frame. These plates being covered with HDPE plastic on the surface which contacts the support frame to substantially reduce vibration.
