Description

Technical Field

[0001] The utility model relates to a safe anti-skid lifting device for a crane, belonging to the technical field of crane equipment in the metallurgical industry. Background Art

[0002] Crane slings are devices used to lift heavy objects during lifting operations. The most commonly used slings are hooks, and others include lifting rings, lifting suction cups, clamps, and lifting beams. Lifting suction cups, clamps, and lifting beams can be used as special slings on cranes for a long time, or as replaceable auxiliary slings hung on hooks for temporary use. They are often used in warehouses and yards with multiple types of goods to improve work efficiency. The slings for grabbing bulk materials are generally grabs with jaws that can be opened and closed, and electromagnetic suction cups can also be used to absorb magnetic materials such as metal chips; the slings for lifting fluid materials are commonly used barrels and hanging pots. Generally, molten steel or chemical solutions are unloaded by tilting or pulling out the bottom plug, and fluid materials such as concrete are unloaded by opening the bottom door of the hanging pot.

[0003] The crane sling has the following defects during the use of lifting: first, the suspended object is easy to slip out of the hook mouth of the hook, which poses a safety hazard; second, when working in a dark place, the sling is equipped with a lighting device, and after working for a long time, dust is easy to adhere to the lighting device and it is inconvenient to clean, affecting the lifting operation. Therefore, a crane safety anti-slip sling is proposed to solve the above problems. Utility Model Content
