High torque Separated Down-the-Hole Drilling(YRSD-750) drilling rig is a multifunctional drilling rig with the highest level in the current split machine. The reinforced design of the drill arm can carry a maximum of 3 tons of guide rail components. The longest guide rail can be drilled up to 6 meters in one time. It solves the trouble of changing rods in some processes. The Sanlian iron pump adopts a well-known domestic brand to ensure the long-term operation of the machine. The installation of a winch is suitable for steep slope operations. High torque Separated Down-the-Hole Drilling is especially suitable for large-aperture operations such as foundation pit drilling and photovoltaic holes of about 300mm.
