Drawworks Manufacturers as a Part of Every Endeavor to Discover Oil

Once there is reason to believe the existence of black gold on a site, the drilling team moves in with their mobile drilling rigs. Standing at around 40 ft. high, these rigs consist of a winch and drilling shaft. The winch is connected to high-powered drawworks beside the rig tower, which in turn controls the drilling shaft’s ascent and descent. While the drilling shaft does all the heavy work, isolated components like drawworks enable it to do its job.
