The 10T crane hooks blocks produced by our company is reliable in quality and welcome to purchase
crane hook blocks can be divided into the following forms according to different purposes and weight:
1. Forged hook:
Forged hooks are divided into single hooks and double hooks. It is generally forged from 20, 20MnSi steel. Because the single hook is eccentric, the force is less than the symmetrical force of the double hook. Therefore, the small and medium-sized tonnage cranes under 75 tons use a single hook, and the cranes with a large tonnage of 75 tons or more use double hooks. This type of hook is widely used and has been formed into a series. When the wire rope is in danger of being unhooked, it is safe for the device.
2, the chip hook:
The chip hooks are also divided into single hooks and double hooks. Generally, a plurality of C3 and 16Mn steel plates are repeatedly riveted. The hook has a simple structure, reliable work and convenient maintenance. Single hooks are used in casting cranes, and double hooks are used in general cranes of more than 100 tons. Their structural dimensions have also formed a series.
3, lifting ring:
The lifting ring is more favorable than the hook. When the lifting weight is the same, its self-weight is lighter, but it is convenient to use without the hook, so the use of the lifting ring is far less common than the hook. It is mainly used on cranes that work frequently and carry heavy loads. Its structure is divided into two types: integral and articulated, and the latter is used more.
