Explosion-proof chain block is also made of different materials, and explosion-proof chain block is mostly made of copper. Why doesn't it make sense? The main materials of explosion-proof chain block include aluminum bronze and beryllium bronze. Aluminum bronze chain block is more common and widely used, while beryllium bronze is suitable for occasions with higher working hardness because of its higher hardness. When in use, the chain pulled by hand drives the driving pinion to rotate, and the pinion drives the big gear to rotate, and the amplified torque is output, thus lifting the heavy object. There is a ratchet and pawl mechanism on the inner side of the zipper strip, so that the sprocket can only rotate in one direction.
