YT29A air leg rock drill quality performance that is not ugly in downtown Blowing no one asked the United States in the mountains chasing someone. Masters YN29A internal combustion rock drill, although far in Jining, you can still find! For more information, please call ①⑤ zero ⑨②⑥⑥ ②⑨①①. YT29A type air-leg rock drill is a heavy-duty air-leg rock drill, with high efficiency, low consumption characteristics, especially for railways, roads, utilities and other building construction use, but also metallurgy, coal mine roadway excavation and various drilling operations replacement. YT29A type air-leg rock drill suitable for medium-hard and hard (f = 8 ~ 18) horizontal and inclined drill holes can be drilled meow rod hole up on the rocks, blast hole diameter is generally 34-45 mm, effective drilling economy hole depth of 5 meters. According roadway size and operating conditions can support FT160A type gas leg FT160C type long-winded leg, FT160B Short FT170 air leg or leg-type gas, but also with drilling rigs supporting car or dry, wet rock.
