The biggest advantage of the down-the-hole drilling rig is its ability to minimize energy loss during rock drilling. Unlike conventional drilling rigs, the down-the-hole rig utilizes an impactor that directly dives into the hole, reducing the impact energy transmitted through the drill pipe. This design effectively mitigates the negative impact of hole depth on rock drilling efficiency. By reducing energy loss, the down-the-hole drilling rig enhances drilling performance and improves overall efficiency.

Main feature:

1. The down-the-hole drilling rig is equipped with dual hydraulic rotary motors, enabling fast drilling speed and improved efficiency in rock drilling operations.

2. The compact structure design of the rig results in a small overall footprint, making it suitable for constrained work sites where space is limited.

3. The rig is mounted on a crawler platform, ensuring stability and allowing it to operate in diverse and challenging working conditions. Its adaptability to various terrains and harsh environments makes it a versatile choice for different drilling applications.
