D480RC Reverse-Circulation Sampling Drill Rig
1.D480RC series drill rig is designed for DTH drilling with a hole diameter of 120mm to 150mm, and is equipped with a 6m drill rod to drill up to a maximum depth of 42m.
2.D480RC has a track type heavy-duty chassis equipped with a hydraulic oscillation device for the track frame, with a oscillation angle of +/-10°, allowing the rig to travel and operate on rough terrains.
3.The track for tramming is 350mm wide, with 171 pitch triple-grouser road-gripping track shoes.
4.The low-RPM high torque tramming motor with a reasonable weight distribution of the whole rig enables D490A drill rig to travel smoothly on a 25°slope.
it adopts a structure of double drill boom and aluminum alloy double feeding beam. The heavy-duty double boom structure greatly improves the bearing capacity of the boom, and the structure is safe and reliable, meeting the heavy load requirements of large hole diameter and large hole depth of DTH drill rig. Double aluminum alloy feeding beam have high strength, disturbance resistance, and good stability.
5.The power rotary head of D490A adopts a cycloidal hydraulic dual motor, which can provide a turning torque of up to 6500Nm. The symmetrical structure of the driving motor ensures smooth and stable movement of the rotary head on the feeding beam, providing a reliable benchmark for controlling drilling accuracy.
6.Cumins engine. An fuel-saving device has been added to the power pack and there is also optional configuration of an automatic preheating device. It effectively reduces fuel consumption and is more adaptable to harsh working conditions such as extreme cold and heat. The optional whole-set preheating system allows the drill rig to operate normally in extremely cold environments of -40℃
7.Equipped with a two-stage compression screw high-pressure air compressor with a pressure of 25 bar and a capacity FAD of 33m³/min, providing ideal power for the rock drilling system and achieving energy-saving and environment-friendly rock drilling operations. Sufficient air volume ensures the flushing effect of the blasthole, improves efficiency, and saves drilling
tools.
8.Dust collector of D480RC is an integrated dust collection box with dual fan structure, equipped with automatic timing-control self-cleaning dust removal. The dust removal effect and the service life of the dust removal filter element are definitely better than other models.
Meanwhile, the dust hood of feeding beam can move up and down, and the collaring operations can be clearly observed, allowing for the control of collaring.
9.User-friendly joystick with unique control functions corresponding to various actions. There are no actions that require linking operation and overlapped operation, maximizing the elimination of misoperations.
