This configuration maximizes mechanical efficiency and the “floating” sub base isolates the components from shock loads and maintains the alignment. The on-off regulation system of the high pressure compressor can remove load during non-drilling operations; extending compressor life, saving energy, and providing easier set-up.Raising the tower with a full complement of drill pipes in the carousel and under the rotary head can be accomplished in less than one minute. Tower pinning and pipe changing is performed remotely from the operator’s cab. Breaking pipe joint is done by a hydraulic-positioned, sliding, fork wrench with limited impact that minimizes shock loads on the tower and other components. A hydraulic motor rotates the carousel to index the rotary head for changing.
