Summary for Patent: 7,819,207
Title:Mobile land drilling rig and method of installation
Abstract: A mobile oil, gas and geothermal well drilling rig provides for the rapid placement, assembly, disassembly, and repositioning of various rig components of the drilling rig. The drilling rig includes a support base and working floor which is trailerable and which can be rapidly erected to a working height at the well site.
