Uses of the DTH Drilling Rig:
The DTH Drilling Rig is useful for drilling and excavating rock anchor cable holes, anchor rod holes, burst holes, and grouting holes in urban construction, railway, highway, river, and hydropower projects, among others.
Features of the DTH Drilling Rig：
1. The rotary power for the DTH Drilling Rig is provided by an electric motor through a high-performance reducer, and the propulsion power is provided by a cylinder. Since there is no hydraulic system, the mechanical efficiency is excellent, the cost is low, and the performance is consistent.
2. The reducer and motor are less likely to be scorched and damaged when the DTH Drilling tool becomes stuck thanks to anti-seize protection.
3. The machine is lightweight and simple to move; its total weight is less than 500 kg, and it can be disassembled into three pieces, making it simple to move and store.
4. The use of rolling dragging plates makes it difficult for the track to become worn out.
5. The DTH Drilling Rig uses semi-automatic cloud technology to break apart the drill pipe, which has a high working efficiency.
