The air winch is a kind of winch that uses the compressed gas provided by the air compressor as the power source. Compared with the traditional electric winch, the air winch has the characteristics of explosion-proof, dust-proof and liquid splash proof, which is more suitable for working in harsh environments. Therefore, the air winch is widely used in ships, oil mining, mining and electric power industries.
