Safety technical standards for the use of shackles

Shackles are actually called armor removers and snap rings. They are a kind of sling tool, which are mainly used to connect rope buckles or components or rings. Because the shackle has the characteristics of small size and large carrying capacity, it is widely used in the field of crane equipment.

To ensure the safety and reliability of the shackle, the following technical standards for the use of the shackle should be met:

The raw materials of the shackle used for lifting can not be cast iron or cast steel. Pay attention to the maintenance of the shackle and not drill holes in the shackle. When the shackle is used, it should be ensured that its surface is smooth and flat, and there should be no serious defects such as cracks and overburning. When the shackle has cracks and other defects, it is not allowed to recycle it by welding repair and other methods. The shackle body or the shaft pin is permanently deformed or the damage reaches the scrap standard and should be replaced in time.

During the construction process, avoid serious friction, fatigue damage, deformation and other abnormal conditions of shackle parts. Please pay attention to the use of shackles: the transverse distance is not allowed to be tensioned, and the safety pin must be inserted into the shaft pin to ensure the safe operation of the equipment. When installing the shackle components, follow the correct installation steps and methods to avoid serious early wear and tear of the shackle due to installation errors. In addition, remember that the use of the shackle is strictly prohibited from exceeding the rated load.
