The very essence of our economic life and growth depends largely on the continuous improvement and development of electronic and mechanical fields. To help these fields, we have MOBILE PNEUMATIC CRANE, mechanical type, which can be widely used to lift the products as less weight or heavy weights blocks, machines, work pieces and etc....
Pneumatic systems in fixed installations, such as factories, use compressed air because a sustainable supply can be made by compressing atmospheric air. Air usually has moisture removed, and a small amount of oil is added in the compressor to prevent corrosion and lubricate the mechanical components. Pneumatic power pneumatic users need not worry about poisonous leaks, since the gas is usually just air. Smaller or standalone systems may use other compressed gases which present a choking hazard, such as nitrogen, often referred to as OFN (oxygen free nitrogen) when supplied in cylinders. Any compressed gas other than air is a choking hazard - including nitrogen, which constitutes 78% of the air. Compressed oxygen (approximately 21% of air) is not asphyxiated, but is not used in pneumatically operated devices because it is a fire hazard, more expensive and offers no advantage over the air. Portable pneumatic tools and small vehicles such as Robot Wars machines and other amateur applications are often powered by compressed carbon dioxide because containers designed to keep it as soda containers and fire extinguishers are readily available and the phase change between liquid and gas makes it possible to obtain a larger volume of compressed gas from a lighter container than the compressed air requires. Carbon dioxide is an asphyxiation and can be a freezing hazard if improperly ventilated.
