Track link assembly

The track link assembly is a core component of the undercarriage “four‑wheels‑one‑track” system of rotary drilling rigs. It forms a closed chain by connecting multiple track links in series. Working together with drive sprockets, idlers, track rollers and carrier rollers, it bears the whole‑machine weight and transmits travelling power. It adapts to muddy, gravel‑covered and uneven construction‑site ground. Due to the heavy self‑weight of rotary drilling rigs, the track link assembly is subject to enormous tensile, impact and bending loads.

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.
