It is well known that the lifting chain needs to be lubricated regularly, which is conducive to safe and efficient operation, saving labor and improving work efficiency. However, do you know how to lubricate the lifting chain? Here are some lubrication methods for you.
The first is to lubricate the lifting chain with grease. After heating, the butter flows into the friction surface of the bypass drive. This method is more thorough, and the butter has strong adhesion and long service time; Second, lubricate the lifting chain with a brush, and fill the lifting chain with lubricating oil with a brush or oil filling pot; The third is drip lubrication chain or spray lubrication chain. The lifting chain shall be lubricated regularly to prevent accidents, effectively reduce the downtime for maintenance, and improve the working efficiency and service life of the lifting chain. How to relieve the use pressure of Grade 80 lifting chain? Grade 80 lifting chain is made of high-quality alloy steel, with strong toughness and strength. It can often be encountered in some large projects. How can it be used to relieve its pressure? First, develop correct lifting habits, plan how to hang, mark lifting points and data, and confirm the center of gravity before use; Second, the weight of suspended objects should not be full or even overloaded; Third, Grade 80 lifting chain and hook shall be hung vertically above the center of gravity of the lifted object; Fourth, the lifting of lifting objects should not only avoid damage to the lifting objects, but also prevent damage to the level 80 lifting chain itself. To avoid rotation or falling, the following premises should be observed: 1. For single-leg rigging, the lifting point should be vertically above the center of gravity of the lifting object. 2. If it is a two-leg rigging, the suspension point should be on both sides of the lifting object, and the lifting point should be above the center of gravity. 3. In case of three-leg and four-leg rigging, the suspension point should be evenly located at the level of the center of gravity of the lifted object and above the center of gravity of the lifted object. Compliance with the above requirements can greatly relieve the service pressure of Grade 80 lifting chain and extend the service life of Grade 80 lifting chain.
