During the use of the mini mucking loader, butter is the most frequently used oil and is used in almost every shift. So when customers purchase a tunnel mucking machine, they need to have a detailed understanding that the lifespan of the mucking machine with and without butter can differ by 3-4 years, and the maintenance cost can differ by tens of thousands.
So, a good mini mucking loader operator is one who frequently pours butter, and a good on-site manager is one who strictly demands in pouring butter. Our scraper uses No. 3 butter and is equipped with a butter gun at the time of departure, making it convenient for customers to apply butter. There are butter cups at the locations where butter needs to be poured, mainly at the pin shaft of the excavator, the copper sleeve on the hydraulic cylinder, and the axle of the chassis.
The mucking machine manufacturer requires butter to be applied every shift to ensure lubrication and improve service life. Based on the calculation that butter is used on each bus, 25 kilograms of butter can last for approximately 2-3 months.
