1. Core drilling machine is a medium-shallow hole core drilling machine. It is a vertical shaft core drilling machine which is mainly engaged in diamond drilling and is suitable for various drilling process requirements. It can be matched to the corresponding motor or diesel engine. The rig structure is simple to disassemble and easy to operate. 2. Geological survey exploration, road and high-rise building foundation exploration, various concrete structure inspection holes, river dykes, roadbed grouting hole drilling and direct grouting, civil water wells and ground temperature central air conditioning, etc. 3. The drilling machine adopts automatic telescopic rig, which is supported by two high-strength oil cylinders. A group of hydraulic valves control the rig to sit on the back, which saves time and labor, is safe and reliable, and maximizes the benefits for users. 4. The chassis adopts rubber track, which is light in weight and low in life cycle cost. It can reduce the noise of the vehicle running mechanism, reduce the vibration of the vehicle body, and greatly reduce the fuel consumption. It can walk on urban roads without hurting the road surface. 5. The chassis comes with four high-strength threaded legs (or hydraulic high-legs) installation and adjustment is quick and convenient, can be used for work plane leveling, loading and unloading vehicles to reduce lifting costs and improve efficiency, can be used as an auxiliary support during work.
