As we all know, explosion-proof chain block is mainly used in flammable and explosive environments. Because of its special material, it will not produce mechanical sparks when colliding with each other, thus cutting off the explosion source from the source. The lifting belt is made of synthetic fiber, and it is impossible to produce mechanical sparks. Is it possible to lift it in flammable and explosive places at will?
That's not the case. If the lifting belt is used for lifting operations in flammable and explosive places, explosion-proof treatment is also required. Of course, the explosion factor is not mechanical sparks, but static electricity. We should be very familiar with static electricity, which is a kind of physical phenomenon commonly existing in nature and has similarities with mechanical sparks.
The so-called static electricity is a kind of charge in a static state or a charge that does not flow. When the charge gathers on an object or surface, static electricity is formed, and the charge is divided into positive charge and negative charge, that is to say, the static electricity phenomenon is also divided into positive static electricity and negative static electricity. Positive static electricity is formed when positive charges gather on an object, and negative static electricity is formed when negative charges gather on an object.
However, the hazards of static electricity are the same as mechanical sparks, so do not assume that lifting belts will not produce mechanical sparks, so you can carry out lifting operations in flammable and explosive environments at will. The lifting belts used in flammable and explosive environments are also anti-static lifting belts with special treatment.
