As a multi-functional machine, HFR160D can realize the quick switching of functions such as crowd cylinder, crowd winch, CFA, and dual rotary drive to meet more different construction needs. Cummins electronically controlled turbocharged engine ensures strong power, convenient and efficient service. With a maximum output torque of 160kN • m and a maximum speed of 35 r/min, the rotary drive can work more efficiently.
The main and auxiliary winches both adopt single-row rope technology. The service life of wire rope is 2~4 times longer than that of multi-layer rope and the cost is lower.
The parallelogram luffing mechanism with a double swing arm has a large support angle and a 24% increase in support range, which makes the operation more stable.
The hydraulic system adopts negative flow control technology which has a fast response and good handling performance.
The high-power dual hydraulic oil cooler is suitable for construction in high-temperature areas.
The intelligent control system can achieve functions such as automatic adjustment and display of mast perpendicularity, automatic slew, and spin-off, etc. With a large diameter slewing bearing, the TDP series hydraulic crawler chassis dedicated to rotary drilling rigs ensures better working stability.
