1. Applications of XYX-130 wheeled hydraulic core drilling rig Geological survey and exploration, basic exploration for roads and high-rise buildings, inspection holes for various concrete structures, river embankments, subgrade grouting holes, direct grouting, civil water well and ground temperature central air conditioners. 2.Features of XYX-130 wheeled hydraulic core drilling rig The drilling rig is equipped with wheeled walking mechanism, which is convenient for the whole machine to move. Also, because of the oil pressure feeding mechanism, the rig improves drilling efficiency. The drilling rig is equipped with a ball card holding mechanism instead of chuck, and it can be operated without stopping the rod. The working efficiency is high and the operation is convenient, safe and reliable. The drilling rig is equipped with pressure gauge so the operatpr will know the bottom hole condition during drilling process. 3.Technical parameters of XYX-130 wheeled hydraulic core drilling rig XYX-130 wheeled hydraulic core drilling rig Drilling depth 130m Max open hole caliber 220mm End hole caliber 75mm Drilling rod diameter 50mm Drilling angle 90°-75° Drill weight 950kg Spindle  Spindle speed 142 285 570r/min Spindle stroke 450mm Windlass Maximum lifting weight of single rope 1600kg Single rope lifting speed 0.41 0.82 1.64m/s Drum diameter 140mm Wire rope diameter 13mm Wire rope capacity 27m Mud pump Type Horizontal single cylinder double action Displacement diesel engine / motor 95/77 l/min Maximum pressure 1.2mpa Work pressure 0.7mpa Drilling depth 130m Max open hole caliber 220mm End hole caliber 75mm
