Reliable HY18 Rock Drill Equipment

The HY18 rock drill is a high-practicality equipment tailored for medium-to-high hardness rock drilling scenarios, with core advantages focusing on "broad hardness adaptation + stable efficient operation". Its **rock hardness adaptation range of F=6-20** covers most industrial rock types—from relatively soft sedimentary rocks (F=6) in shallow mines to hard metamorphic rocks (F=20) in deep tunnels. This eliminates the need for frequent equipment replacement when facing different strata, greatly improving on-site operation flexibility. Its structural and performance parameters are precisely designed for efficient rock drilling. The 51mm piston stroke and 58mm cylinder diameter form a balanced power transmission combination: the longer piston stroke enhances the impact force of the drill bit, ensuring effective rock breaking; the matching cylinder diameter optimizes air flow, reducing energy loss during impact. This structural design directly translates to faster drilling speed—compared t…
