Gasoline Rock Drill Jack Hammer for Construction(YN27C)
The internal combustion drill is a tool used to directly extract stone. It drills holes in the rock formations so
that they can be put into explosives to blow up the rock to complete the excavation of stone or other
stonework. In addition, the rock drilling machine can be changed into a breaker, used to break the hard
layer of concrete.
YN27C Gas Powered Jack Hammer Rock Drill for Mining Equipment Introduction
The internal combustion rock drill is a drilling machine with fuel combustion as its driving force, and is a hand-held
rock-drilling tool composed of small gasoline engine, compressor and rock drilling machine. Mainly used for drilling
down, horizontal and up to less than 45 ° hole, replace a few parts, can be changed to crusher or tamping machine,
used for a variety of shovel chisel, crushing, digging, splitting and ramming work. Since the machine has its own
power, the production of compressed air to blow the hole, it is particularly suitable for high mountains, no power, no
pressure gas equipment areas and large liquidity of temporary works. Widely used in Open-pit mining, excavation of
frozen soil, road construction, cable laying and water conservancy.Application of YN27C Gas Powered Jack Hammer Rock Drill
YN27C Inter Combustion Rock Drill suited to work on high mountains, plains, hot and cold area with no power and
no water supply and air compressing equipment, and especially suits the projects that the machine has to be carried
at any time and in any area.

Working principle:
Internal Combustion rock drill is a kind of new rock drilling machine powered by small power internal combustion
engine (two-stroke gasoline engine), which is suitable for field operation without power supply and air compressor.
According to the needs of the work, internal combustion rock drills in addition to rock drilling operations, generally
equipped with more than 10 kinds of tools (such as grinding wheel, picks, spades, shovel, etc.), can be broken,
shovel chisel, digging, splitting, ramming and so on operations.
