Product Introduction

The CMJ1‑14Y mining crawler hydraulic drill jumbo is independently developed and manufactured by Jiangsu AnNeng Drilling Equipment Technology Co., Ltd. It is designed for blast hole drilling in small roadways, tunnels and underground projects including non‑coal mines, metal & non‑metal mines and water conservancy projects. Applicable section size: 2.0m×2.0m ~ 4.0m×4.0m. Equipped with full‑vehicle wireless remote control, auto‑leveling drill arm, anti‑jamming & anti‑empty striking hydraulic system, cable towing device, and compatible with multiple brands of hydraulic rock drills, it delivers accurate and multi‑angle drilling in narrow roadways. It replaces labor‑intensive manual pneumatic drills and bulky conventional jumbos to realize full mechanization for small tunnel excavation.

Product Advantages
