YT28A air leg rock drill

Product Details

YT28A air leg rock drillWidely applicable, it is most suitable for drilling horizontal, inclined, or vertically upward boreholes on medium hard and hard (F=8-18 levels) rock formations. The diameter of the borehole is 32-42 millimeters, and the effective and economical drilling depth can reach 5 meters. This machine can be used in conjunction with FT160BD short air legs or FT160BC long air legs according to the size of the tunnel section.

The YT28 pneumatic rock drill is the most modern rock drill product, which adopts the design technology of modern rock drills. Compared with similar products, it has the advantages of high efficiency, low noise, light weight, good economic effect, and fast footage speed. It has superior performance and is the most reliable to use. The most efficient rock drill. It is most suitable for rock drilling operations in large mines, medium-sized mines, and tunnels, and has received the best response from domestic users. Its market share in North Korea has reached over 70%. Adopting mechanisms such as air-water linkage, quick retraction of air legs, and air pressure regulation Concentrate the control handle with the handle body. The institution is innovative and easy to operate. The accompanying soundproof cover can effectively reduce noise and change the exhaust direction at will, improving on-site working conditions. Compared with similar rock drills, it is lighter in weight, quieter, more efficient, and has better economic benefits.
The YT28 pneumatic rock drill is widely used in mining, tunnel excavation, and various rock drilling operations. It is an important tool in metallurgy, coal, railway, transportation, water conservancy, infrastructure and national defense rock engineering This machine is used for wet drilling operations on medium hard or hard rocks, with a muzzle diameter of 34-42mm and a drilling depth of up to 5m. It can be paired with FT160BD short air legs or FT160BD long air legs to drill horizontal and inclined boreholes; It can also be installed and operated on a trolley or bracket.

Product features:
The YT28 air leg rock drill is a small rock drill powered by compressed air; Used for drilling in medium and hard rocks. The mechanism is simple and easy to operate, with two types of operation modes: dry or wet. Wet drilling can effectively reduce dust and provide certain labor protection. The body is made of high-performance Austenitic ductile iron castings. Make the body not only have the high strength of carbon steel forgings, but also have higher wear resistance than carbon steel forgings; Effectively extend the service life of the product.
