DTH drillingrig is a self-designed new energy-saving and efficient rock drilling device and essential to open-pit mining. It is extensively used in mid-depth blast hole drilling operation in small and medium mine and road building, national defense, water conservancy and rock excavation projects and especially suitable for rugged area where other drills are unable to operation. It is of compact structure, easy to operate and handle, and completely dismantled with fast drilling speed and high efficiency.

Characteristics of DTH drilling rig

It is the first product of its kind in China to use hydraulic design technology into light DTH drill innovatively to realize high efficiency and energy-saving.

Driven by hydraulic motor, it has large rotation torque and is free of rod sticking.

Its unique drilling rig locking structure ensures that the drill holes have accurate and consistent angle.

Its unique counterweight device enables the drill to operate stably and reliably without Capacity.

The control mechanism is concentrated for easy and fast operation.

It is economic, efficient and energy-saving to use motor as the turning power.

It adopts cycloidal pin wheel speed reducer with straight-tooth transmission to realize large rotation torque and high drilling efficiency.

Novel overload protection enables the drill to operate stably and reliably.

Feed, rotation and impact are all powered by the compressed air, thus it is easy to move with simple structure and single power.

Unique dual muffler provides good performance and reduces environmental pollution.

Partial types of DTH drill have three optional supporting structures, such as single center, double-center and bearing type to be adapted to any landform.
