XR160E-1320 Rotary drilling rig

The rotary head achieves a maximum output torque of 168 kN·m and a rotational speed up to 35 r/min, delivering superior working efficiency. It adopts a double‑boom large parallelogram luffing mechanism with a large supporting angle. Its supporting coverage is increased by 24%, ensuring more stable operation. Fitted with a Cummins electronically‑controlled turbocharged engine, it features strong power, great fuel compatibility and convenient & efficient service support. The main hydraulic system applies negative‑flow control technology. A high‑displacement main pump is matched with a low‑speed engine to realize lower fuel consumption and higher efficiency. The intelligent control system realizes automatic adjustment and display of mast verticality, automatic up‑and‑down soil shaking, automatic forward‑reverse soil‑dumping of the rotary head, ground‑touch protection and other functions. The whole machine is more intelligent with enhanced operation convenience and safety. It is equipped with TDP‑series special hydraulic crawler chassis for rotary drilling rigs and a large‑diameter slewing bearing for better working stability. The complete machine can be transported with drill rods installed, which is fast and convenient.

XR400E-1427 Rotary dilling rig

Technical Characteristics It adopts double-boom luffer and H-style. Dedicated hydraulic retractable crawler chassis and large diameter slewing bearing to provide extraordinary stability and transport convenience; Cummins electric control turbo-supercharged with three gears engine is used, it has strong power.According to specifie working conditions, the users can select a corresponding gear of the engine, getting the drilling rig working as three engines. The main hydraulic system adopts the negative flow control, and adopts the main power control and limit power control together which can increase the system efficiency and make the most of the engine power. It adopt three-in-one cooling system which is tightly packed and has a high-efficieney in cooling. It adopts the single-rope for main winch to figure out the wear of thel steel rope, and extend the life-span. The rotary drive can switch from Nromal Mode,Rock Mode and Energy-Saving Mode, the user can select a corresponding mode of the rotary drive according to the specific working conditions, which can greatly improve the working efficiency and lower the fuel consumption. Optional configuration according to customers' requirement, E.g: Crowd winch, Outrigger cylinder, Sleeve-driven and so on.
