Yt28 Air Leg Drill for Rock Drill for Mine Tunnel Drilling Operation and Rock Mining Hand Held Rock Drill Pneumatic Rock Drill

Product Description

Introducing the YT28 Air-Leg Rock Drill, an epitome of high-efficiency, energy-saving, and eco-friendly rock drilling technology. The YT28 stands out among pneumatic products with its remarkably low failure rate, rapid rock drilling speed, and extended lifespan of wear parts. Additionally, it boasts low noise levels, lightweight design, and user-friendly operation.

Product Description

 

1. The YT28 features a moderate height and extensive stroke range, enabling it to drill anchor holes perpendicular to the roof surface. This unique capability addresses the long-standing issue of non-perpendicular anchor holes in roadways, ensuring enhanced project quality and progress while reducing construction costs and boosting efficiency.
2. Offering stellar rock drilling performance, the YT28 is adept at drilling in medium-hard rocks and rocks with a hardness coefficient of f≤6. Its versatility makes it suitable for both rock roadways and quasi roadways.
3. With a simplified structure, the YT28 is notably durable and easy to maintain, leading to lower maintenance costs.
4. The YT28 features a flexible start mechanism, air-water linkage, fast air-leg return, and air pressure adjustment systems, ensuring operational efficiency.
5. The control handle is integrated with the shank body, offering a novel and convenient operation. The muffler cover effectively reduces noise and allows for directional adjustment of exhaust, enhancing field operation conditions.
6. The YT28 Rock Drill is ideal for wet drilling in medium to hard rock conditions.

Application Areas:

Mining, transportation ,tunnels, water conservancy projects, quarries, and various other construction works.

YT28 pneumatic air leg rock drills before use

1. Inspect the integrity and rotation of all parts (including rock drill, bracket, or rock drill cart) before drilling. Fill necessary lubricant, and ensure wind and waterways are smooth and connections are firm.

2. Check the roof near the working face for live rocks and loose rocks, and perform necessary treatments to ensure safety.

3. The working surface for shell hole location should be pounded flat in advance to prevent slippage or shell hole displacement.

4. It is strictly forbidden to drill dry holes. Always insist on wet rock drilling: turn on water first, then wind when operating, and turn off wind first, then water when stopping. Start drilling at low speed and increase to full speed after reaching a certain depth.

5. Drillers must not wear gloves while drilling to avoid safety hazards.

6. When using the air leg to drill, pay attention to your stance and position. Never rely on your body to pressurize, and avoid standing in front of the rock drill to prevent injury from broken brazing.

7. If abnormal sounds or water discharges are detected during rock drilling, stop the machine for inspection. Identify and resolve the issue before continuing.

8. When withdrawing the rock drill or replacing the brazing rod, operate the rock drill slowly and pay attention to the position of the brazing rod.
