Lubrication of large crane
Lubrication is necessary for large crane. It can control friction, reduce weariness, down crane temperature, avoid rust and form seal. These functions rely on each other and influence each other. If the friction can’t be controlled, the weariness can/t be reduced, this will lead much friction heat and items high temperature, thus to damage the friction surface lubrication and lubricating material.
Some parts should be lubricated regularly, such as shafts, holes and friction surface with relative move. Due to different working condition, the lubricating points are different. For various kinds of cranes and different lubricating parts, every lubrication should meet the standards and requirement of instructions. It is good for crane to make regular lubrication and check. Lubricating with qualified oil can ensure the crane work normally and avoid early weariness. Bad oil can lead mechanical accident, even damages equipment, influences safe producing.
Lubrication plays an important role in crane’s maintenance. The lubricating oil can influence the effect directly.
