Foot chain hoist hook material

Electric  wire rope hoist  lifting heavy mainly used for the connection between the hoist and the weight is particularly important piece, electric chain hoist connections greatest advantage is unmatched selection and workmanship, the following detailed description of electric chain hoist foot hook material, allowing you to learn more about.

Forging chain hoist equipment  hook generally use DG20 steel and DG34GrMo other alloy steel, forging and stamping, annealing and then machined made ​​with high strength, ductility and good toughness. Jun sheet generally used for large tonnage by intense physical blazing hot grill place. Usually a thickness not less than 20mm A3, 20 # 16Mn steel plate or sheet-hook, a sudden rupture does not occur, and high reliability.
Fracture due to defects confined to individual plates, and the remaining still supporting lifting plate, the individual plates can be simply replaced, so it has greater security. But only create a rectangular sheet-like section of the hook, the hook material can not be fully utilized. Because there are more quality casting material defects, so electric chain  lift hoist  shall not use steel hook, the hook can not be welded, nor can the high intensity, low impact toughness of steel manufacturing.
Forged hook should be printed in low stress areas marked with a nominal weight, factory standard, inspection mark, date, number, etc. marked by forging surface inspection and load tests, to provide qualified documents.
