Audited Supplier
The Air-Legged Rock Drills from Xianghe Kaituo Mining Machinery Co., Ltd. represent the pinnacle of heavy-duty, air-legged rock drilling technology. Engineered for low energy consumption, these drills excel in creating horizontal or inclined boreholes in medium-hard to hard rocks (f=8-18). They are versatile enough to drill anchor holes either upwards or downwards. Adaptable to various roadway section sizes and operating conditions, the YT29A can be paired with FT160A (or FT160B, FT160C) or used on drill trucks and frames for both dry and wet rock drilling. Additionally, our comprehensive range of YT29A rock drill parts includes pistons, rotating sleeves, spiral rods, brass nuts, valve sets, ratchets, tower springs, manipulation valves, shank bodies, cylinder bodies, main bodies, brazing sleeves, brazing cards, brazing card bolts, oilers, water injection valve bodies, fastening pins, ratchet pawls, air pipe nuts, air pipe elbows, water needles, and more.
1. Enhanced Output Power: Delivering top-tier performance with increased efficiency.
2. Swift Rock Drilling Speed: Experience faster penetration rates for maximum productivity.
3. Superior Lubrication System: Ensures prolonged operation of moving parts, reducing wear and tear.
4. Optimized Machine Design: The perfect balance of impact energy and frequency makes this the ideal tool for rock drilling.
5. Advanced Gas and Water Linkage: Features quick gas-leg return, air pressure adjustments, and more for enhanced operational efficiency.
6. User-Centric Control: The control handle is centralized with the back head for novel and convenient operation, while the muffler cover effectively reduces noise and allows for adjustable discharge direction, improving field working conditions.
Application Areas:
Ideal for mining, traffic tunnels, water conservancy construction, quarries, and more.

Before Using the Rock Drill:
1. Ensure all parts (including rock drill, bracket, or rock drill cart) are intact and well-lubricated. Check for smooth wind and water pathways and secure connection joints.
2. Inspect the roof near the working face for live or loose rocks and address any issues before starting.
3. Ensure the working surface is flat before drilling to avoid slippage or displacement.
4. Always drill with water to avoid dry drilling. Start with water, then wind when operating, and reverse the sequence when stopping. Begin at low speed and switch to full speed once a certain depth is achieved.
5. Drillers must not wear gloves when operating.
6. Pay attention to standing posture and position when using the air leg. Do not pressurize with your body and avoid standing in front of the rock drill to prevent injury from broken brazing rods.
7. If abnormal sounds or water discharge occur, stop the machine, inspect, and resolve the issue before resuming.
8. When withdrawing the rock drill or replacing the brazing rod, operate the drill slowly and be mindful of the brazing rod position.
Price advantage
As an integrated industrial and trade enterprise, we offer factory-direct pricing!How long will it take to deliver?
Being the manufacturer, we arrange production immediately upon order confirmation. For items in stock, expect delivery within 15 days; for larger orders, delivery may extend up to 30 days.
