The PVT PDR391RH is a professional mine hydraulic mining drilling vehicle specially designed for narrow roadway mining operations , featuring high stability, high productivity and low operating costs as its core advantages. Equipped with the high-performance LD120SH 22kW rock drill, it supports a borehole diameter range of 60-127mm and is matched with a precise 360° rotatable orientation system, realizing accurate and efficient drilling construction. The product adopts a compact structural design, adapting to the narrow roadway working environment with a minimum roadway size requirement of 3,000×3,000mm, and its optimized transportation size ensures convenient transfer in mines. Integrated with complete hydraulic, wind & water, and electrical systems, it is equipped with multiple safety protection functions (FOPS standard safety roof, low oil level alarm, phase sequence protection) and a humanized operating system (wired remote control, adjustable seat), fully meeting the safety and efficiency requirements of modern mine drilling operations.
