Good quality: 1) The material of the hook is 20Cr, which has a strong pulling force and is not easy to deform; 2) The material of the main shaft, gear, and lifting wheel is 20CrMnTi, with a working life of 1500 hours; 3) The chain is made of 20Mn2 G80 standard material, which has 4 times the breaking force; 4) The hand zipper is 5mm thick. It has the advantages of long service life, light hand pulling force, and safety guarantee when lifting.
Poor quality: 1) The hook is made of A3 steel, which has a low tensile force and is easy to deform; 2) The main shaft and accessories are made of 45# carbon steel, with a working life of only 200 hours; 3) The chain is made of A3 steel, which is relatively thin, only 0.8~ 1.2 times the breaking force; 4) The hand zipper is 4mm thick. The service life is short, the chain will be stuck, and the hand pull is laborious when lifting, and there is no safety guarantee.
