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.
Applications:
Available for drilling, splitting breaking, ramming, shoveling. And widely used in mining, road contruction, quarrying and national defense construction, etc.
The pneumatic pick is a tool with compressed air as its power. The compressed air is distributing alternatively through the tube-shaped distributing valve into either end of the cylinder, so that the hammer is reciprocating motion in it, which impacts the tail-end of the pick rod and drives the pick rod into the rock or strata of mine, thus causing them to split into pieces.
