 XY-1 Core Drilling Rig
is a light type machine at high speed with hydraulic feeding. XY-1 are designed on the basis of XY-1
Applications:
1. Drillings for the general exploration and investigation of solid mineral deposit, engineering geotectonic survey and concrete structure inspection holes.
2.Diamond drill bit, alloy drill bit and steel roller drill bit and so on are available for drilling according to different geological structures.
 3.When the final holes are respectively 75mm and 46mm in diameter, the rated hole depths are separately 100m. The maximum of depth may not exceed 110% of that drilled in each hole. The maximum allowable hole diameter is 150 mm.
Features:
1.With hydraulic feeding device, elevated drilling efficiency, reduced labor strength.
2.The rig is equipped with an upper spherical jaw holding mechanism and hexagonal drive drilling rod which can be replaced without shutdown, high efficiency, safe and reliable.
3. A hole bottom pressure gauge is mounted indicating the pressure in order to control the status inside the hole.
4.Compact structure, small volume, lightweight, high detachability, easy transportation and suitable for the operations in plains or mountain areas.

Technical Specifications
 

Used for general investigation, geophysical exploration, high-way and building construction, and blast-hole drilling etc.With hydro-automatic feeding device, and high drilling efficiency.Designed with hydro-chucking unit instead of slips to ensure drilling from stop when changing pipes.Close levers, convenient to operate, safe and reliable operations.Compact in structure. All the drill, water pump and diesel engine installed on one base frame result in space-saving.Light in weight, easy disassembling for transportation and applicable to working conditions in plain and mountain areas.
