Machine for Geologic Drill Derrick Dismantling and Assembling and Drill Derrick with Mechanically Reversible Assembling

Abstract:

The shortcomings of present drill derrick dismantling and assmbling are pointed out with solutions proposed. A dismantling and assembling machine for four-leg drill derricks and a mechanically assembleddrill derrick have been developed, which are thought to the trend of the geologic drill derrick.
