Air-Hydraulic DTH crawler drill KGH8 is our smallest crawler mounted, down the hole pneumatic drill rig, and is ideal for work in confined areas. It is a fully mechanized, self propelled, heavy duty drill. It is a simple one-man operated rig, easy to operate and easy to maintain. The tramming controls are located beside the left track, and both tramming and drilling are powered by hydraulic motors.

　　Features & benefits

　　Hydraulic tramming, positioning and feeding system

　　Equipped with hydraulic system, making it efficient

　　Compact rugged crawler

　　Powerful and reliable engine

　　It using 4-cylinder diesel enging for power,traction power larger and Climbing Ability,libration smaller and Working Stability

　　New boom

　　It using the better trolley travelling mechanism and the circular boom, novel structure, convenient adjustment, expands the range of drilling,It can drill the hole low level.

　　Safe and stable travelling system

　　Low gravity center,high ground clearance,It can travel on the rough terrains.Special wheel motor drive, strong climbing ability, low failure rate

　　Advanced automatic balancing and braking system make the dill can travel stability,driving safety.

　　Prevent to take off the chain set is improve the properties of dirll.

　　It can travel without compessor.

　　Powerful feeding and rotating system

　　New slewing mechanism is composed of cycloid hydraulic motor and the planetary gear reducer, provides a powerful torque, reduce the rate of drill

　　High power hydraulic motor drive feed mechanism can produce 20 kn lifting force, to adjustregulating valve for the best propulsion.
