Goodeng machine returns the style of the king----“GD450AT-LS Dual-wall Pipe rock drilling machine” comes into market gloriously

In the accelerated development process of urbanization, trenchless directional drilling technology has been widely used in many fields, rocking drilling is more and more common. Traditional rock drilling technology is with high cost, low efficiency and high pollution factors, which puzzles the trenchless construction enterprises at home and abroad. On the basis of a large number of market research, with keen insight into the development direction of trenchless construction technique, a new type of horizontal directional drilling is developed---“GD450AT-LS Dual-wall Pipe rock drilling machine”. This HDD machine has come into market gloriously in June 2016.

GD450AT-LS Dual-wall Pipe rock drilling machine is developed on the basis of traditional trenchless drilling rig. and it is new horizontal directional drilling which apply to all strata of trenchless construction. It is new rock drilling technology whose drilling head is driven by outer pipe, and inner drill pipe drives roller bit to break rocks. Not only the drilling efficiency is greatly improved, but also the construction cost is significantly decreased. It will replace traditional rock drilling technology which is the combination of hdd machine and mud motor drive in the future. Besides the unique characteristics of Goodeng common hdd machine, GD450AT-LS Dual-wall Pipe rock drilling machine has the obvious advantage of "two high and one low", which is pioneering the new era of all terrain construction.

1.High configuration

GD450AT-LS Dual-wall Pipe rock drilling machine is equipped with powerful Cummins power system, Germany originally imported Rexroth (international first-class brand) main hydraulic system, Humanized multi-functional operation cab (optional), Automatic loading and unloading drill rod manipulator, crane and so on.

                      

2.High efficiency

GD450AT-LS Dual-wall Pipe rock drilling machine adopts double pipe drilling system, Outer drill pipe drives guide drilling, and high-speed rotating inner pipe drives roller bit to fast break rock strata. Construction speed improves greatly, and construction drilling efficiency is more than 50% higher than that of traditional drill.

3.Low cost

GD450AT-LS Dual-wall Pipe rock drilling machine can drill and do the project without mud motor, which saves the expensive mud motor costs. Inner drill pipe drives roller bit, small amount of pump can easily break the rock, which can save a lot of mud costs. High efficiency can shorten the construction time greatly and save a lot of fuel and labor cost etc.

With “two high and one low” huge advantage and high performance-price ratio, GD450AT-LS Dual-wall Pipe rock drilling machine must will be "weapon" of any region, any strata of trenchless construction. Goodeng Machine always adhere to the core values of "create value for customers”, constantly create high quality equipment for the customer, provide more perfect service, and hope to create a more brilliant tomorrow with the global trenchless customers together.
