yt28 portable breaker grouting drilling
yt28 hilti drill machine is suitable for hard or harder in the (f = 8 ~ 18) of the rock drill hole horizontal or inclined direction, but also vertically upward to drill bolt holes on the roof. Inch hole is generally φ34 ~ 45 millimeter, drilling and effective depth of up to 5 meters.
the machine can tunnel cross-section according to the size and type long-winded ft160bc legs, ft160bd short legs supporting the use of gas can also be mounted on cars or diamond drilling rack use.
the machine is equipped with fy200b-type injector, operating time can provide self-lubricating, its outside the use of transparent polycarbonate shell material, easy to observe the oil surface, regulate oil, rock drilling machine at work to ensure good lubrication.
works:
yt28-type rock drill to use compressed air as a driving force to promote the pistons reciprocating motion. Stroke, when, pistons impact drill with chisel rock fragments; return trip, pistons lead solder with a certain rotation angle, continuous shocks, turning so that brazing with round-shaped carved into the rock hole.
features:
operating mechanism to focus, start a flexible, gas-water interaction, use and maintenance easy; noise, vibration small, energy-saving high efficiency, long life wearing parts, blowing hole cleaning ability, and high reliability.
