The shank adapter plays a crucial role in rock drilling tools, serving as a vital component that directly withstands the intense impact and torsion generated by the rock drill. It facilitates the transmission of impact energy from the piston movement of the rock drill to the drill rod and ultimately to the drill bit, enabling efficient rock drilling. The inner hole of the shank is exposed to rapid water flow and the damp conditions prevalent in mining and rock drilling environments, subjecting the shank to mineral water corrosion.
Hydraulic rock drills typically operate at working pressures of around 20Mpa, with some reaching as high as 25Mpa. The frequency of impacts per minute can range from 3000 to 4000 times. Consequently, the shank operates in an environment characterized by high speed, high frequency, and robust impact, making it a critical component of the hydraulic rock drill.
In meeting the working conditions and performance requirements of shank adapters, the core material must possess not only excellent toughness but also sufficient strength to withstand high-impact contact fatigue. Additionally, given the unique and complex shape of the shank, material selection must consider the bending fatigue strength of the shank, necessitating a material with adequate hardenability.
In the world of top hammer drilling, where reliability, strength, and performance dictate success, professionals demand components that can handle the toughest conditions without compromise. That’s why experienced contractors and mining engineers rely on the Shank Adapter HL RD HLX—a premium-grade connection engineered for HL, RD, and HLX rock drills.
Whether you're working on a mine face, tunneling project, or large-scale quarry, the Shank Adapter HL RD HLX ensures maximum impact energy transfer, minimal wear, and extended service life.
