Maintenance of double beam driving hook group

Everyone knows that the lifting device will use the double beam driving hook group when lifting various items. In fact, the type of double beam driving hook group is more than we imagined. There are single and double beam driving hook sets. Beam driving hook sets can also be said to be linked together with different products.

Let me introduce the classification and use of the double beam crane hook group:

1. The double beam driving hook group is forged by the whole piece of key material (usually using No. 20 high quality carbon steel), and needs to be annealed, and the hardness requirement is 95-135 (HB).

2. The surface of the double beam driving hook group should be smooth, and there should be no defects such as cracking, nicking, sharp angle, crack, etc. The well is not allowed to repair and repair the damaged double beam driving hook group to avoid accidents.

3. The sling should be hung to the bottom of the hook when lifting; if the double beam driving hook group is directly hooked into the lifting ring of the component, the double beam driving hook group cannot be hardened or twisted.

4. The double beam driving hook group has a single hook and a double hook type. The hoisting work generally uses a single hook, the main size and lifting weight of the double-beam driving hook set with ring.

5. If the double beam driving hook group has permanent deformation and cracks, it should be scrapped. When the wear reaches 10%, it should be downgraded or replaced.
