1.Forging hook material adopts high-quality low carbon killed steel or low carbon alloy steel, such as 20 high-quality low carbon steel, 16Mn,20MnSi,36MnSi, which is annealed after being forged.
2.Strap type hook: riveted through several pieces of cutting forming steel; When individual plate has flaws, the whole hook is not damaged. Good safety ,heavy dead weight; mainly equipped with big lifting capacity cranes or cranes lifting molten steel ladles.
Semi-circular guard in shell over sheave prevents wire from slipping between shell and sheave. This feature also greatly strengthens the plate in the shell.
Steel sleave over center pin gives a bearing surface of large diameter.
This sleeve is held tightly between the plates and makes the block extremely rigid.
