IntroductionShip launching airbags are to be constructed of a cylindrical body and two conical heads (one at each end). Ship launching airbags with lots of advantages, such as easy to operate, time saving, saving investment safety, etc.
Major Strengths of Ship Launching Airbags:
High level of safety: Equipped with a reliable safety valve, our airbags can stand the maximum pressure up to 4 times that of the operating pressure.
Good air tightness: Pressure decreases less than 10% for a period of 24 hours.
Long lifespan: It is guaranteed that our airbags can sustain their designed operating pressure for 3 years.

Air picks are tools driven by compressed air.The compressed air is distributed into two ends of the cylinder in turn by the tubular distributing valve to make the hammer conduct reciprocating impact movement and impact the tail of the pick, so that the air picks are driven into the rocks or the strata of ores, splitting into pieces.Pneumatic air picks are applied mainly in crushing reinforced concrete buildings, cement, permafrost, icy sheets of layers, soft ores, soft rock, pavement construction. We have five models of pneumatic air picks: G10, G11, G15, G16 and G20, in which G11 and G16 are anti-freezing pneumatic air picks.
