China No Dig Drilling Machine Horizontal Directional Drilling Machine Ddw-4518

Underground drilling for water pipes DDW-4518
DDW-4518 Horizontal directional drilling rig adopts the steel track driven self-contained design with its aesthetic appearance and compact structure. It is applicable for installation of oil and gas pipeline, water supply and wastewater pipe line, as well as power, cable and other pipeline installation project. It is not only suitable for crossing river and channel, but also widely used in crossing road, rail way, airport, coast, island, mountain, tropical rain forests, as well as the area which does not permit of excavation such as crowded buildings, cultural relic presserve zone, pipeline located region.

Key features:
1. Heavey-duty chassis, the drill rig is stable and rugged, Steel track with its rubber mat, need not worry about destroy the rod surface.
2. Thrust system is driven by rack and pinion for high transmission efficiency, and long life.
3. Pullback system adopts combination of high speed variable displacement piston motor, reducer and broker for three speed adjustable, and supply high speed and efficiency.
4. Cummins construction machinery desicated enginer for strong power. Fully performance with advantage of machine power requires less energy than competitor's models, but higher efficiency.
5. With 14000 Nm of torque and 45T of pullback force, it is ideal unit for installations of long distance and large diameter pipe.
6. Adopt famous original imported product or owned enterprises product which provide reliable quality and performance, after sales service guaranteed.
7. Optional pipe loader, closed operating cab and hydraulic anchor reduce the labor intensity and saving cost, humanization design is fully reflected.
