250m Crawler Water Well Drilling Rig

400C Multi-functional crawler well drill is a new efficient and multi-functional hydraulic-pressure drill; the drill is mainly used in drilling operation such as water drilling well. Exploration well and geothermal air conditional well, etc. In stone drilling, DTH hammer is applied in the operation, slag is discharged by air pressure, the offstage is ten times of that of the traditional rotary drilling.    Technical ParameterModel: 400CMax. drill depth:250mDrill diameter:110-325mmDiesel Engine: 93KW (Cummins)Working air pressure:1.05-2.46MPaAir consumption:16-34 m³/minDrill rod length:3m   Drill rod diameter:89mm/76mmAxial pressure:  5t  Lifting force:12tSlow lifting speed:4m/min    Fast lifting speed:14.5m/min  Slow feed speed:6.2m/min  Fast feed speed:25m/minRotation torque:5700-6600Nm, 2820-3300Nm             Rotation speed:0-90r/min, 0-180r/minDrilling Method:Downhole hammer or Mud DrillingTravel speed:3.5Km/hGrade ability:21°Weight:7.8 tWhole dimension:6×2.1×2.8mApplication formation:Unconsolidated layer or bedding rockDrill method: Down the hole or mud pump drillingHammer:Medium or high air pressure series  /* 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
