The S shape Forged sling hook is made of alloy material, so that it will not break when working under external overload, but will gradually deform, with a higher Factor of safety; The new design at the hook head ensures that the goods do not unhook. The hook is often hung on the steel wire rope of the lifting mechanism with the help of components such as pulley blocks.
1. Features: High strength and high-quality alloy steel die forging.
2. Suitable for use with grade 80 rigging accessories.
3. The manufacturing inspection tension is 2.5 times the rated load. Sample 20000 cycles of cyclic fatigue testing at 1.5 times the rated load.
4. Conduct magnetic particle testing 5 The minimum breaking force is 4 times the rated load.
What precautions must be taken when using the S shape Forged sling hook
For cranes, the hook is a very important equipment and directly affects the lifting compliance. Below, we will learn about the application method of the S shape Forged sling hook.
(1) The S shape Forged sling hook cannot be forged, and the difficulty of forging has quality drawbacks, which cannot ensure the mechanical properties of the material.
(2) Usually, the S shape Forged sling hook is forged from a whole piece of steel. The surface should be lubricated and free from defects such as cracks, nicks, peeling, and sharp corners. It is prohibited to weld and repair absolutely worn or cracked hooks, as the repaired hooks may become brittle. Causing a rupture after being subjected to force, resulting in an accident.
(3) Welding hooks and steel hooks cannot be used. Due to the significant impact load on the S shape Forged sling hook during retraction and braking. Therefore, excessive strength cannot be used. Made of materials with low impact toughness.
(4) When using a rope buckle to hook, the rope buckle should be hung to the bottom of the hook. When using an S shape Forged sling hook to hook the lifting ring of a component. The S shape Forged sling hook should not be hard or twisted to avoid deformation or straightening of.
