As a professional rock drilling machinery factory with years of experience, Xianghe Shenli Pneumatic Machinery Co., Ltd. specializes in manufacturing high-quality pneumatic tools, including the YT29A air-leg rock drill—a core equipment for mining operations designed to solve inefficiencies of traditional drilling machines. The YT29A is a heavy-duty air leg rock drill powered by compressed air, featuring centralized operation mechanisms, flexible startup, and air-water linkage for easy use and simple maintenance. It weighs only 29kg, with a drilling diameter of 34-42mm and a maximum drilling depth of 5m, suitable for drilling horizontal, inclined and anchor holes in medium-hard to hard rocks (f=8-18) in mines, tunnels and other projects.
Using the YT29A is straightforward: ensure the air pressure is 0.45-0.55MPa (efficiency drops below 0.4MPa, and parts wear accelerates above 0.55MPa) and water pressure is lower than air pressure to avoid water backflow. Before use, blow out moisture and impurities in the pipeline, and inject 3-4ml of qualified lubricating oil per minute to protect internal components. Regular replacement of wearing parts and keeping the air source clean can maintain its optimal performance.
Compared with ordinary rock drills used in mines previously, the YT29A brings revolutionary improvements. Traditional rock drills have low energy utilization, slow drilling speed, high noise and frequent failures, requiring 2-3 workers to operate alternately and completing only 15-20 meters of drilling per day. In contrast, the YT29A’s optimized internal structure increases impact frequency to over 2000 times per minute, improving energy utilization by 15% and drilling efficiency by 40%—completing 25-30 meters per day with only 1 worker, greatly reducing labor intensity and operational costs.
Choosing Shenli Pneumatic Machinery means choosing reliability and efficiency. Founded in 2005, our factory covers 23.5 mu, adjacent to Beijing with convenient transportation, and has passed ISO9002 quality certification. We cooperate closely with international brands like Japan Toku and US Gardner Denver, adopting advanced technologies and first-class production processes to ensure product quality. The YT29A not only boosts drilling efficiency by 40% but also reduces failure rate by 60% and noise by over 40%, with modular design for easy maintenance and 30% longer service life than ordinary drills. It saves energy, improves working environment and ensures continuous operation, creating greater value for mining enterprises.
