1. The crawler down-the-hole drilling rig is novel in design and reasonable in structure. Drilling rig travel, drilling tool rotation, axial propulsion, etc. all adopt hydraulic transmission mechanism. Easy to operate, easy to maintain, low energy consumption and high efficiency, it is a new high-performance and economical down-the-hole drilling rig in my country.
2. The crawler down-the-hole drilling rig is suitable for drilling blast holes in small and medium-sized open-pit mines. It is also suitable for perforation and blasting construction in areas without power supply such as highways, hydropower, building materials, chemical mines, and railways. At the same time, it can also be used for construction in areas with power supply.
3. The crawler down-the-hole drilling rig can be equipped with different types of impactors according to the needs of users, which can be used for low-pressure and high-pressure down-the-hole drilling operations.
