The tongue on the chain sling hook (usually referred to as a safety tongue or anti slip tongue) plays a crucial role in lifting operations. Here are several key points of its importance:

1. Prevent heavy objects from falling off

Blocking effect: The main function of the safety tongue is to prevent heavy objects from falling off the hook during lifting. It utilizes the self-locking principle of spring contraction to automatically block the opening of the hook when the heavy object shakes or tilts, ensuring that the heavy object will not accidentally come out.

Closed ring: The safety tongue piece forms a closed ring when the hook is closed, increasing the safety during the lifting process.

2. Ensure work safety

Reduce the risk of accidents: In lifting operations, if heavy objects accidentally fall off, it can not only cause equipment damage, but also potentially cause serious injuries to workers. The presence of safety tongue significantly reduces the risk of such accidents.

Improving work efficiency: When the safety tongue is intact and working properly, workers can focus more on the lifting operation itself without constantly worrying about heavy objects falling off, thereby improving work efficiency.

3. Easy to operate and maintain

Easy to pick up and hang: Safety tongues are usually designed as pushable. When heavy objects need to be picked up or hung, simply gently press the tongue to open the hook opening, which is convenient and fast.

Inspection and replacement: Regularly inspecting the safety tongue to ensure its integrity is an important step before lifting operations. Once damage or failure of the tongue is found, it should be replaced promptly to ensure the safety of subsequent operations.

4. Material and Performance

Material selection: Safety tongue plates are usually made of high-strength materials such as cast steel to ensure sufficient load-bearing capacity and durability.

Performance requirements: Although the hardness and strength of the safety tongue are not as good as the hook body, it still needs to meet certain performance requirements to play a blocking role at critical moments.

5. Follow norms and standards

Industry regulations: In the lifting industry, there are strict regulations and standards for the design, manufacturing, installation, and use of safety tongue plates. Following these regulations is an important guarantee for ensuring the safety of lifting operations.

Manufacturer's advice: Different manufacturers may provide different usage and maintenance recommendations based on the characteristics and performance of their products. Following these recommendations can extend the lifespan of the safety tongue and ensure its proper functioning.
