Product Description

35T Horizontal Directional Drilling Rig for Pipelaying DDW-3512H

DDW-3512H 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 pipeline, as well as power, cable and other pipeline installation project. It not only suitable for crossing river and channel, but also widely used in crossing road, rail way, coast, island, mountain, tropical rain forests, as well as the area which does not permit of excavation such as crowded buildings, cultural relic preserve zone, pipeline located region.
Key features:





 
 Control system

• Main pump for rotary and pull back is Electric proportional plunger pump which is high efficiency, High bearing pressure capability and Long life.
• Dual speed for rotary,pull back and track moving, controlled by electric proportional control system and continuously variable transmission.

• All-in-one multifunctional controller, rotary,thrust/pull back as well as other main action. It supplies simple, convenient and comfortable efficient operation.
• Four-bar swing arm linkage structure provides steep entry angles without raising the tracks off the ground; ensure the stability of drill rig in operation.
• Wrench skewed 10 degrees inward, towards the operator, easy to observe wrench action.
• Wrench with buffer spring avoids damage the thread of drilling rod and wrench by human error.
• Rack-and-pinion thrust structure, the rotary head is driven by double pullback motors and reducers.
• Steel track with rubber blanket provides high strength and long life;
• Wire control system for dual speed track moving, safe and reliable.
