Hydraulic Down The Hole Rock Drill Crawler Coal DTH Blasting Drilling Rig

Product Parameters Product Description HCR-8 Full Hydraulic Core Rig - an up-to-date Multifunctional and high capability product made by Lianyungang Huanghao Machinery Factory Co, Ltd, is a thoroughly new-type hydraulic core drilling developed with reference of HYDX-series Full Hydrau-lic Core Rig and feedback of clients, t is suitable to be used in plains, as well as severe atmosphere places and conditions such as high temperature and cold weather, lt is mainly used for metal & nonmetal sold mineral exploration and exploration of coal-bed methane, natural gas mining; hydrogeology well drilling, geothermal well drilling, mining gallery, ventilation and drainage of exploratory and emergency construction project, lt can also be mainly used in the field of geology, metallurgy, coal mine, non-ferrous mining and oil, hydrological and engineering drilling, lt's one of the multifunctional and excellent performance core rig by using diamond and carbide-tipped bits mainly and the same time it can meet the demand of wire-line coring and top drive.optional bracket device optional bracket device1, Full hydraulic drive, steel Crawlers, assembly type mast, the machine is integrated and compact for easy operation in structure consisting of power station, main hoist, wire line winch and mud pump, etc.2. lt is adopted dual pump and motor and closed-loop hydraulic circuits for rotation of unit head: and open-loop design is adopted for all other hydraulic transmission, lt is adopted precursor control and load-sensing for the hydraulic system, The system is controlled by electro-hydraulic proportional integratedly and intensively.3. The structure of doubling system between cylinder & chain is adopted for the feeding and lifting of drill head, i.e, with the function.if the piston rod of oil cylinder moving one certain distance, the spindle movement will double the distance, Lifting capacity and feeding capacity is separately up to to 295 kN , 152kN .Detailed Photos   Dril Head CapacityRotary Speedr/min0~12503 gear stepless speed adjustmentMax.TorqueN-m7200 Hole Diameter of Spindlemm121 Max Lifting CapacitykN295 Max feeding powerkN152 Diesel EngineRated PowerkW264CumminsQSL8.9-C360Rated Speedr/min2200MastMast Heightm15 Adjusting Angle.0~90 Drilling Angle.45~90 Feeding Strokemm4700 Sliding Distance of Mastmim1100 Main HoistSingle-wire Hoisting CapacitykN1201 Layer1Dia,of Steel Ropemm22 Length of Steel Ropem60 Auxiliary WinchSingle-wire Hoisting CapacitykN151 Layer 1Dia,of Steel Ropeim8 Length of Steel Ropem2500 Mud pumpModel/BW-320 Foot clampClamping Scopemm55.5~117.5φ154 Hole diameterWeight of Main Machinet25  (xx)Overall Dimensions(LxWxHmm8165x2530x3030Transport Dimensions/* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
