Different specifications of different materials of the lifting chain are not allowed to mix and match the use, because there is a great load

difference between them, which will lead to different force consumption of both in the process of lifting, and it is likely to occur one party fracture.  So

 in addition to this case, Is it possible to mix old and new chains of the same specification and material? Concerning this problem，

    First of all, we can tell you that the old and new lifting chain is not recommended to mix and match the use, especially the use of a long time of lifting chain is strictly prohibited with the new chain mix and match. Many people save the trouble and cheap not to replace the chain, but the old and new chain together with the use, so there is a great potential safety hazard. 

    It is necessary to know that the use of the chain is a process of loss, and the longer the use of time, the greater the loss, when a larger loss of the lifting chain and a lossless chain collocation is used, The load capacity of the former will be reduced and the safety factor will be reduced. If the two do not match, one side of the old chain may be broken. At the same time with the new chain collocation together, the load of the new lifting chain will be greater, accelerating the loss of the new lifting chain, and shortening the service life of the lifting chain. 

    Combined with the above points, we can draw the conclusion that the old and new lifting chains must not be mixed to use, when the lifting chain appears to have greater wear or fracture, we must replace the whole chain, to ensure that the lifting chain longer and safer operation.
