The production of hand -to -hand gourds lies in the quality of parts, good quality in components, saving effort and long service life. The hood of the gourd hood is selected into one -to -mold thick alloy steel hood to resist the durability. Metal steel hooks can be rotated at 360 degrees. It can be used both to use it, or it can be used vertically like a gourd. The streamlined card slot design is sturdy and durable, and the chain is smooth. The chain uses G80 manganese steel to stand up to the chain, with high strength and strong toughness. Even if it breaks, it will not break immediately, but there will be a certain extension. However, you don't have to worry about the chain break at all, because the dedicated lifting chain is 2.5 times the test load and 4 times the broken load.
