Rotary drilling rig upgrading friends

Rotary drilling rig upgrading it in 2004, we invented the installation of rotary drill excavator patent, creating a pile foundation into a new pattern of holes, small wheeled rotary drilling, rotary drilling small crawler. It has gone through a decade in which the market conservatively estimated at thousands. Small pile into the hole on the market has played a large rotary drilling irreplaceable filled function, of course, which also has many imitators, shoddy (such as Shandong Tengzhou many imitators), disrupting the market at low prices, high failure rate, the device features a single, Use only in a loose geological conditions. Today, we are creating another revolution, can solve even large rotary drilling can not achieve the effect, we all know, there are three problems pile into the hole, a large diameter, 2, landslides, 3, hard geology (rock) we The rotary drill can solve these problems; a large diameter into the hole no longer have to spend millions of dollars to purchase equipment, weight equipment no longer need dozens of tons, transitions no longer have special vehicles, spending huge shipping. Second, the deal collapse without casing, do not rub the machine. Third, completely out of the pressure pattern, whether it is machine-locking drill pipe pressure, or pressure cylinders plus wire rope, even hard texture layer (formation) is also no longer have the pressure method, of course, we do not have DTH and air compressor supporting, can still effectively into the rock.
