Electric hoists represent their own machinery, strength, and toughness, while the stage is elegant, flowing, and soft, with conflicts and collisions between the two.

  What are the requirements for the shape of the lifting chain

  The lifting chain is made up of chain links spliced together, and each link we see is elliptical. So why is it elliptical? What is the reason for this? Next, we will reveal to you

  That's because the elliptical structure has an advantage in terms of operating feel and performance:

  1. The elliptical structure has no edges and corners, and the user's feel is also comfortable. Otherwise, it may feel prickly and even scratch their hands during operation.

  2. The elliptical structure has a smooth surface without any edges, making it smoother to operate and reducing wear on the wheel axles.

  3. The circular surface is smoother, and the reason why ellipses have an advantage is that ellipses can achieve a stable effect and save volume, making collection relatively simple.

  The above is an explanation of why the design concept of lifting chains is circular. Do you understand?

  Key points during lifting chain inspection

  During the use of the lifting chain, when we need to inspect it, we need to carefully observe and check if there are any of the following phenomena in the chain.

  1. Is there any abnormal noise or vibration during operation, and is the lubrication status of the lifting chain in good condition;

  2. The allowable wear value of the chain shall not exceed 10% of the diameter of the circular ring chain rod or the thickness of the auxiliary tool;

  3. Starting from the non curved plane of the main ring, if the main ring is twisted more than 10 degrees, it should be scrapped;

  4. Whether the inner/outer chains are deformed, cracked, or corroded;

  5. Whether the pin is deformed, rotated, or corroded;

  6. Whether the rollers are cracked, damaged, or excessively worn;

  7. Whether the joint is loose or deformed;

  8. Cracks, bending, or twisting in any part of the chain, as well as jamming or stiffness between the ring hinges that cannot be ruled out, are prohibited from use;
