1.Application Range

(1)Geological exploration, physical geography exploration, road and building exploration, and blasting drilling holes etc

(2)Diamond bits, hard alloy bits and steel-shot bits could be selected to meet different layers

(3)Suitable for 2 to 9 stages siliceous skin clay and bedding course etc. layers

(4)The nominal drilling depth is 100 meters; the maximum depth is 120 meters. The nominal diameter of initial hole is 110mm, the maximum diameter of initial hole is 130 mm, and the diameter of final hole is 75 mm. The drilling depth depends on different conditions of stratum

2.Main Features

(1)Easy operation and high efficiency with the hydraulic feeding

(2)As the ball type chuck and the driving rod, it can complete no-stopping rotating while the spindle relit

(3)The pressure indicator of bottom hole can be observed and the well conditions controlled easily

(4)Close levers, convenient to operate, safe and reliable

(5)Compact size and use same base for the installation of rig, water pump and diesel engine, just need small space

(6) Light in weight, easy to assemble, disassemble and transport, suitable for plains and mountain area
