YN27C Internal Combustion Rock Drill
1.Introduction of YN27C internal combustion rock drill
The YN27C internal combustion rock drill has various functions such
as mining, drilling, building construction, geological exploration,
cement pavement, asphalt pavement and other functions such as
splitting, crushing, compacting and shovel. It is widely used in
mining, road construction, quarrying, construction, railway
tamping, geological survey, national defense engineering, etc.
2.Features of YN27C internal combustion rock drill
You only need to move the handle as required to complete the
drilling or crushing operation.
The machine is easy to operate, saves time and labor, and has the
characteristics of fast cutting speed and high efficiency.
The machine has reached the first-class level of similar products
and can be completely interchanged with international similar
The drilling can be vertically downwards, horizontally upwards less
than 45°, and vertically drilled up to six meters.
The weight of the main machine is only 27 kg. Only one person can
operate it. It is easy to carry. It is suitable for areas with high
mountains, no power supply, no wind pressure equipment and
temporary projects with large mobility.
This machine has wide adaptability in both high mountains and flat
land, regardless of the extreme heat of 40° or the cold region of
This machine adopts export packaging, and all the indicators meet
the export standards. This product is exempt from inspection and
does not require commodity inspection for export. Since only
gasoline needs to be added to work, no other auxiliary equipment is
This machine is suitable for mining of various mines such as iron
ore, copper mine, nickel mine, lead-zinc mine, gold mine, gemstone
mine, granite, bluestone and jade.
