Product Description

Hl820st Hydraulic Top Hammer Rock Drill

Robust Rock Drill

The main body modules are connected by four side bolts, minimizing the number of joint faces and large contact surfaces. Its simple percussion module has only two moving parts: the piston, distributor sleeve and moving parts are never in contact with the drill body modules.

Two Rotation Motor Variants

To meet the torque and RPM requirements of different hole diameters and rock formations, the rotation motor comes in two types.

Patented Power Extractor (Option)

The drill offers the optional power extractor for manual or automatic opening of rock tool joints when using one-hole or fan automation.
