Features Introduction

Product Description

The JCM290 Ultra-Deep Hole Full Hydraulic Anchoring Drilling Rig is purpose-built for large-diameter and deep anchoring construction requiring high accuracy and efficiency. Featuring an extended drilling mast with a 10,500 mm rotary head stroke, the rig enables one-pass vertical drilling of up to 10 meters, greatly reducing rod handling time and improving overall construction efficiency. Its extra-large clamp system supports diameters up to 430 mm, making it ideal for heavy-duty anchoring and foundation reinforcement projects.
Designed for flexibility in complex working conditions, the JCM290 adopts a two-section detachable mast structure that allows vertical, horizontal, and inclined drilling configurations. With low-speed high-torque output up to 17,000 N·m, rotary–percussive drilling capability, and precise drilling angle monitoring, the rig ensures stable penetration and accurate borehole positioning in hard rock and deep formations. The swingable operation panel further enhances operator comfort and control, making the JCM290 a reliable solution for demanding civil engineering, mining, and geotechnical applications.
