3, can be at the minimum distance of the hook opening to select two suitable locations to print easily wear marks, measuring the distance of the mark, as the use of the detection of the basis of the change in the opening.

4, the hook material can choose 20 high quality carbon steel or hook special material dg20mn, Dg34crmo and so on forging, prohibit use casting hook. Hoist Hook The material of the hook is generally used A3, C3 ordinary carbon steel, or 16Mn low alloy steel

5, the technical conditions of homemade hook should conform to GB 10051.1-88~GB 10051.5-88 (New standard: GB10051.1-2010~GB 10051.5-2010)
