S82/YT29S air leg pneumatic rock drill
Scope of application:
Model S82 air-legged rock drills are heavy-duty air-legged rock drills with high efficiency and low consumption, which are especially suitable for use in the construction of railroads, highways, hydropower, etc. They are also a substitute product for metallurgy, coal and other mining roadway boring and various rock drilling operations.
S82 air-leg rock driller is suitable for drilling horizontal and inclined holes in soft to hard rocks, the diameter of the gun hole is generally φ34-45mm, and the effective and economic drilling depth is 5m, and it can be equipped with FT160A air-leg, FT160C long air-leg and FT160B air-leg according to the size of the roadway section and the operating conditions, and it can also be equipped with drilling car or drilling frame for dry and wet rock drilling
S82 Rock Drill-Torque is more than 10% higher than the YT series
1、Strong gas control system: enhanced sealing, generating stronger rock drilling impact energy, and the field test shows that the feed efficiency is 10%-25% higher than YT28 under different rock conditions.
2、Advanced rotary structure (won the national utility model patent): the torque is more than 10% higher than that of the YT28 product, which can be used smoothly in all kinds of complex rock conditions and exerts fast rock drilling efficacy.
3. Unique cooling and lubrication system (patented by the State Utility Model): two new cooling and lubrication systems are added to improve the operation efficiency of the machine, enhance the service life of the piston, brazing sleeve, and brazing rod, and reduce the replacement cost of parts and accessories.
4、Innovative flushing structure (national utility model patent pending): when the water pressure is higher than the wind pressure, the water injection valve automatically decompresses to prevent the water from backing up to the machine body to produce a stoppage, simple operation and more efficient operation.

Before using the S82 rock drill
1、Check the integrity and rotation of all parts (including rock drill, bracket, or rock drill cart) before drilling, fill necessary lubricant, and check whether the wind and waterways are smooth and whether the connection joints are firm.
2、Knock on the roof near the working face, i.e. check whether there are live rocks and loose rocks on the roof and second gang near the working face, and make necessary treatment.
3, the working surface of the flat shell hole location, is to be pounded flat in advance before allowing rock drilling, to prevent slippage or shell hole displacement.
4. It is strictly forbidden to drill dry eyes, and we should insist on wet rock drilling, turn on the water first and then the wind when operating, and turn off the wind and then the water when stopping drilling. When opening the hole, run at low speed first, and then drill at full speed after drilling to a certain depth.
5、No gloves are allowed to be worn by the drillers when drilling.
6、When using the air leg to drill the hole, pay attention to the standing posture and position, never rely on the body to pressurize, let alone stand in front of the rock drill under the work brazing rod, to prevent injury from broken brazing.
7、If abnormal sound and abnormal water discharge are found in rock drilling, stop the machine for inspection and find out the reason and eliminate it before continuing to drill.
8、When withdrawing from the rock drill or replacing the brazing rod, the rock drill can run slowly and pay practical attention to the position of the rock drill braze.
We are one of the famous rock drilling jack hammer manufacturers in China, specializing in the production of rock drilling tools with exquisite workmanship and superior materials, manufactured in strict accordance with industrial quality standards and CE, ISO9001 quality management system certification. These drilling machines are easy to install, operate and maintain. The drilling machines are reasonably priced and easy to use. The rock drill is designed to be sturdy and durable, not easily damaged, with a full range of rock drill accessories
