Shark pliers are an important part of the marine ship deck machinery. The main function is to clamp the towline wire rope and avoid the steel wire rope swinging left and right during the navigation of the ship to avoid damage to the ship's side and wire rope. Its design and manufacture have long been a foreign monopoly. Based on the successful development of small-tonnage shark tongs in the early stage, Wuhan Shipbuilding has repeatedly carried out simulation analysis through repeated verification of design, and overcome the difficulties in the structure, performance, safety and simulation test of large-tonnage shark tongs, and completed the first 500 in China. Tons of shark pliers and retaining piles.

Effect of dry air on human body
People can easily distinguish the cold and heat of their environment, but the air humidity cannot be clearly perceived. We can't give immediate feedback on the water content of the air we breathe into our lungs or in contact with our skin and body.
However, air humidity will have a significant impact on us. If we are in extreme environment for a long time, it may cause damage.
Dry air draws water from any source it comes into contact with, including our bodies. Water can evaporate from our eyes, skin, hair, nails and any other body surface. This dehydration may initially cause discomfort, such as eye soreness or contact lens irritation, but it may also lead to more serious symptoms, such as dry skin, itching and dermatitis.
What's more, it affects our respiratory and immune systems. When the relative humidity of the air we breathe is less than 40%, the mucous membranes in the nose, throat and bronchus will become dry, and these elements play a vital role in our body's resistance to airborne pollutants (such as viruses and bacteria).
These moist mucous membranes trap airborne particles before they enter our lungs. Tiny hairs called cilia transport these contaminants to our throats, which are then coughed up or swallowed and destroyed. This process is called mucociliary clearance.
When our mucous membranes become dry, this natural defense mechanism will be inhibited, making us more vulnerable to airborne viruses and bacteria.
scientific basis
Over the years, a large number of studies and investigations have been carried out to demonstrate how humidity affects the human body. The following is a summary of these studies. These famous examples illustrate the benefits of maintaining an optimal humidity value for physical health and well-being
