2. The crane hook block is generally made of A3, 20# or 16Mn steel plate, the thickness is not less than 20mm, without sudden break, and the reliability is high.

3. Flaps of hook block are generally used in places with large tonnage in high temperature environments.

4. . All hooks will be equipped with safety latch to prevent the load from unhooking.

5. Ratio of pulley diameter and wire rope diameter is greater than 20 to ensure service life of rope.

Application of Flagcrane Crane Hook Block

  • The single hook is simple to manufacture and easy to use, but the force is not good, and it is mostly used in the workplace with a lifting capacity of less than 80 tons.
  • When the lifting capacity is large, double hooks with symmetrical forces are often used.
  • Laminated hooks are riveted from several cut and formed steel plates. When individual plates have cracks, the entire hook will not be damaged. The safety is good, but the self-weight is large. Most of them are used for large lifting capacity or lifting molten steel ladle on the crane. The hook is often impacted during the operation and must be made of high-quality carbon steel with good toughness.
