Portable Gasoline Powered Jack Hammer YN27C
Application
YN 27 Portable Petrol Rock Drill is a very efficient machine,composed of gasoline engine, Air pump, rock drill. It adapts to these outside situations without water and electronic power. Meanwhile it is a hand- held drill, during operation,rock power is blown away by the compressed air produced by the machine itself. .Its 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.
Available for drilling, splitting breaking, ramming, shovelling. And widely used in mining,road-construction, quarrying and national defense construction, etc.
Characteristics
• Needless to replace the internals of the engine head, just handle
the handle to operate it.
• Easy to operate. More time-saving and effortless. Drilling faster
and more efficient.
• Have reached the Tip-top level of the same field now, and allow
to be replaced with the same kind of the domestic products.
Engine
The engine is a hand operated,single cylinder and two stroke petrol
engine with air cooling,reflux airconversion,no contact
ignition,and no floating-type carburetor.It is composed of control
parts,starter parts,oil tank parts,flywheel
parts,crankshaft,connecting rod,crankshaft case parts,magneto
parts,and piston parts and cylinder parts.
Air Compressor
The engine piston and hammer piston are mounted separately in the
upper and lower place of the cylinder.These two pistons move up and
down synchronously.The hammer piston and the bigger bore of the
cylinder forma compression chamber,which together with air inlet
and outlet valves and ventilator valves,form the air compressor.It
is composed of hammer piston parts and cylinder parts.
Rock drill
It is composed of hammer piston parts,rotation mechanism
parts,drill shank housing parts.
