Pourquoi les excavatrices ont-elles besoin de beurre, Et à quelle fréquence

Pourquoi as-tu besoin de beurre?
Lorsque les pièces de la pelle fonctionnent, il y a des dizaines de positions sur l'avant-bras et le seau qui auront un mouvement relatif, et les broches et bagues de ces pièces ont subi des frictions lors du travail, et en raison de la charge de travail importante de la pelle, la force exercée sur ces pièces est également très importante.
Le 4 pins on the excavator bucket need lubrication

This can be real steel and iron, such a large work intensity if allowed to “dry grinding”, the shaft pin and sleeve will have serious wear, with a few days of gap is very large, affecting the work of the excavator and high maintenance and replacement costs. In order to reduce this part of friction, le PC60-7 track roller/ bottom roller has designed lubricant injection and retention channels in these moving parts, so that an oil film can be formed in the middle of each two moving parts during work to reduce wear. And that lubricant is butter, the technical name for grease.
How often should I beat the butter?
In order to make the digger parts work better, each DH220 Carrier roller has marked the maintenance time of each part on the instruction manual, and the butter is generally filled once every 5-8 hours during the working time, which means that the butter needs to be filled at least once during the work every day.
Can you use gear oil or oil instead?

En fait, this is due to the characteristics of the excavator when working, these working parts of the digger parts are “low speed and heavy load”, and the sealing is not good, if the use of liquid lubricating oil in the work is easy to miss and can not form a good oil film. Donc, the shaft pin of the front-end working device of the Pignon d'excavatrice Komatsu PC300-6 needs to be filled with grease, which has a long retention time and can be glued to each lubricating part to form an oil film to maintain good lubrication.
Finally, the benefits of butter to the digger parts are really great, the speed of wear of the pin and shaft sleeve will be much slower, and the working gap of these parts will be small. Excavators also work with much better noise and accuracy.
