Topic: Crane knowledge: crane lubrication
The lubrication of crane machine is an important part of crane daily maintenance. The quality of crane lubrication not only affects crane operation but also influences the working life of crane parts and components. What’s more important, it affects crane safety and operation efficiency Therefore, the crane maintenance personnel should check the lubrication condition of the crane frequently and refill the lubricant timely.
On the crane machines, there are lots of places that needs to be lubricated. Generally, all contact surfaces of holes and shafts as well as mechanical friction surfaces requires lubrication. There are two ways for lubrication: manual decentralized lubrication and auto centralized lubrication.

Manual decentralized lubrication
Manual decentralized lubrication is usually used by medium and small crane equipment. Manual lubrication is to use lubricating screw or grease cup to refuel the lubrication points separately. The manual lubrication is simple and low cost however it takes longer time for lubrication personnel to lubricate each and every lubrication points, and also, the lubrication holes are easily blocked due to the exposure to dusts. What’s more, it is risky to lubricate some lubrication points manually. Therefore, the centralized lubrication system is used.

Centralized lubrication system
Centralized lubrication system takes the advantage of lubrication pump. When lubrication is needed, the maintenance personnel only needs to refill the lubrication pump, and then the lubricant can be pumped to each lubricant points. It is reliable and safe. Besides, the monitoring system can be installed to monitor the lubrication condition of lubricating points. Because it does not need to stop the crane to be lubricated, the centralized lubrication system is widely used on cranes which are used in the production lines, such as, steel-making production lines, which can largely improves the working efficiency, and also provide a good working environment for the maintenance workers.
