Product Details

The crawler type DTH drilling rig, also known as the DTH drilling rig, is mainly used for rock drilling work in open pit mining, road construction, water conservancy, power station and other projects. Adopting new hydraulic technology, the air consumption is low, the turning torque is large, the shifting hole is convenient, and the propulsion carriage has the telescopic function. When the drilling is carried out, the carriage is supported on the ground with good stability.
