The conventional down-the-hole drill rig can be configured with a modular diesel-powered unit, making diesel engine transfers more convenient and electric motor operations more energy-efficient and environmentally friendly. Equipped with a low-profile propulsion unit, it can adapt to perforation operations in low-height and narrow spaces.

Technical Features

Bidirectional Shock-Absorbing Power Head

A flexible connection is adopted between the power head and drill pipe, effectively isolating the impact from the impactor and rotary vibrations transmitted to the rig, resulting in higher operational reliability.

New Dust Collection Hood

The new two-stage sealing structure and elastic ground-pressing hood body effectively prevent rock debris from spraying toward the rig, making operations safer.

Wide Operating Range

360° annular operation with variable angles, covering hole diameters from Φ76–Φ165mm.
