Classification and advantages of hook groups
Single hooks are simple to manufacture and easy to use, but the stress is not good, and they are mostly used in workplaces with a lifting weight of less than 80 tons; when the lifting weight is large, double hooks with symmetrical force are often used.
The stacked hook is made of a steel plate cut and formed by several pieces. The entire hook will not be damaged when cracks occur in some plates. It is safer, but has a large weight. It is mostly used on cranes that lift large lifting weights or lift steel buckets.
The hook is often impacted during operation and must be made of high-quality carbon steel with good toughness.
Hooks often work in the form of hook sets, because individual hooks sometimes cannot bear such heavy items, and in this case they must be used in the form of hook sets.
The hook group has a semi-enclosed hook group and a closed hook group. So what are the advantages of the hook group?
What are the advantages of a fully enclosed hook group?
The fully enclosed hook assembly has the following characteristics:
1. The cover of the hook assembly is made of steel plates, and the pulleys are all sealed inside. The cover is rigid, which completely eliminates the phenomenon of wire ropes being unrotated and the pulley being stuck.
2. Using a combined closed structure, the pulley is not affected by external collision and will not break; the pulley's structural strength design is enhanced, and its wear resistance generally has the same life as the entire hook group.
3. The cross beam (axis) and side plates of the hook group have enhanced strength (from the working environment), which is more reasonable than the ordinary hook group, has a greater strength, stable and reliable work, and has a service life of 5-10 times that of the original product, and the strong life of the steel wire is the original3-5 times the product, except for replacing wearable parts such as bearings and hooks, the general maintenance cost is zero.
4. This hook group has another valuable advantage. Even if it is "rushed to the top", (the rising limit fails, the collision accident of the dynamic and static pulley set) will only break the static pulley. Due to the good rigidity of the shell, it will not damage the hook group.
5. Starting from the overall structure of the hook combined with reality, except that the hook and hook nut are standard parts (standard of Dalian Heavy Machinery Factory) are interchangeable, the other main stress-bearing parts are not interchangeable with national standard parts.
