Crawler DTH Drilling Machine Mobile Blasting Drilling Rig

Product DescriptionHW420 Rock Blasting Machine    HW-420B/420B-1Separated DTH Surface Drill Rig This model is equipped with a dual-motor rotary head and a multi-way valve with adjustable rotary speed. The rotary torque can reach 2200N.m, which meets the needs of 76 drill pipes and 130 bores. The rotation speed can reach up to 150 revolutions, which meets the needs of some customers for high-speed drilling in soft rock formations. At the same time, the 420 series models are equipped with engineering tracks and plunger motors as standard, which increase the leveling function, improve the climbing and cross-country performance of the equipment, and can adapt to complex terrain conditions. Vertical holes can be drilled for slopes to meet the needs of different working conditions. * Drilling Diameter :90-138mm* Drilling depth: 20m* Engine Power: 58 KW * Competive Price* Site Instrcution and Installation* Professtional After-Sales Team* CE, BV, TUV, ISOTechnical ParameterDiesel Engine SpecificationsRig ModelEngine ModelRated PowerHW-420BYuchai YC4DK8058 KWHW-420B-1Yuchai YC4DK8058 KW (Dust collection system asstandard equipment)General SpecificationsHole Depth30mDrill Pipe Sizes76 X 3,000 mmDrill Pipe Dia90-130 mmRotation Torque (Max.)2200 N.mRotation Speed0 -150 rpmWorking Pressure0.7 - 2.5 MpaF.A.D8 - 20 m3/minFeed Force15KNPull Up Force25KNFeed TypeHydraulic cylinder-chainTramming Speed (Max.)2.5 km/hGradient30°Track Frame Oscilation±10°Total Weight4000 kg/4400KgTransportation Dimensions5700 X 2130 X 2200 mm  Detail Photos Features: 1.
