openair DTH drilling machine

1.High quality instrument,real-time monitoring the machine running state with the function of high temperature stop by the coolant.

2.Cummins supercharged engine,high-efficient and fuel-efficient. High flow dryer air filter match with oil-bath air filter each other perfectly to insure the clean air passing through the engine ,safe and easy to clean.

3.Turret head with big gear wheel and double motors,bigger rotary torque;winch type lifting motor can prevent the drill rod from getting stuck.High polymer material guide rail sliding plate, wear-resisting,self-lubricating,easy to change.guide rail with permanently wear-resistance.24A high strength lifting chain with long service life.

4.Imported hydraulic oil pump with high pressure resistance,large displacement and reliable quality.Original imported travel motor equip with two speed running system;Stable chassis and floating system before and behind the carriage,with the strong off-road capability.

5.Remote driver's seat with broader view and simple operating system.Control valve with compact arrangement is easy to operate and adjust.
