Main Application:

This core drilling rig is widely used in geological general investigation and exploration, road and tall building foundation detection, concrete structure cavity detecting, river levees, subgrade, grouting early detection, civil wells, earth temperature, hydroelectric power-station, highway, roadway, harbor and drilling pile grouting etc.

Main Features:

1. Equipped with wheel undercarrigae device and hydraulic suppeot cylinder, this core drilling rig is very convenient for transport and adjusting the drilling rig level.
2. Hydraulic oil pressure feed device, improves core drilling efficiency.
3. Equipped with normally closed hydraulic chuck, core drilling operation is flexible and reliable.
4. Pressure gauge display the condition of the bottom of the drill hole
5. Drill mast controlled by hydraulic cylinder, improve the core drilling efficiency
6.Diesel engine adopt the electric starter, to reduce the labor itensity.
