After the appearance of Separated Construction DTH Hammer Drill Rigs design, the design makes the whole vehicle relatively simple in structure, with high cost performance, high requirements for on-site management, and unable to move quickly. At the same time, it is different from the whole vehicle power source, and needs to be additionally bridged with the air compressor driving rock drilling system; In addition, compared with integrated drilling rig, its energy consumption is relatively high.

Usually used in various mines and rock excavation projects such as national defense, transportation, hydropower station and so on.
The split crawler drilling rig is a new type of drilling and construction equipment for gas extraction.The industrial test showed that the split crawler rig has moderate dimensions, high flexibility at underground, high comprehensive drilling efficiency, and wide adaptability. It has a good prospect in mines with complex conditions.
