Check the lifting chain, the first check whether the lifting chain deformation, whether there are small cracks, rust, etc. Qualified lifting chain without defects affecting appearance.
In order to check the lifting chain manufacturing details, we can check from the lifting chain wrapping paper welding opening. The paper extends a circle from the chain lifting chain, lifting chain is smooth when touched, no burrs, scratches, etc., this is qualified for lifting chain.
There is no abnormal sound or vibration when used.
Selected for high quality lever lifting chain all made of high quality alloy steel. However, some small lifting chain manufacturers or informal enterprises with rough process or simple materials, the production of lifting chain in the appearance of some deviations or defects.
How to slow down lifting chain wear:
Lifting chains are usually used in lifting operations. However, due to the material problem of lifting chain, lifting chain is easy to wear, coupled with irregular use, leading to many of the original good quality lifting chain was scrapped in advance, increasing the cost of use.
What should we do to slow down the lifting chain wear?
First of all, should firmly grasp the lifting chain tightness. Many companies use elastic or loose lifting chains. Too tight will increase the lifting chain strength and eventually wear. Too loose will lead to lifting chain jumping, unable to achieve the use of the effect.
Secondly, in the process of using the lifting chain, the lifting chain should be regularly injected with oil, which can not only extend the service life, but also greatly improve the work efficiency.
Finally, the storage of lifting chain is also very important. Usually, the lifting chain stored in a dry and ventilated place, should be regularly checked not often used lifting chain, so as not to corrosion.
