1, excavator parts in the use, transportation and replacement process, often bump, paint, rust, etc., especially heavy iron parts, as long as the parts themselves are normal and do not delay the use, most owners will consider it normal.
In fact, it is best to apply a paint film after these parts have lost their paint and rust. Surface painting is a convenient, quick and inexpensive method of protection. If the metal parts have been damaged, the damaged parts must be removed first and then brushed with a rust-proof coating. Do so even if the parts are often used, the possibility of rust is much smaller.
2, the choice of rust-proof layer and lubricant is also a learning curve. For example, old drivers will directly buy calcium-based grease and lithium-based grease, because the long-accumulated experience tells us that these greases can achieve twice the effect with half the effort. The first point goes without saying that they can make the parts achieve the expected use and condition. In addition, if the owner wants to replace the new grease, the original grease can be replaced quickly and easily cleaned.
3, for special cases of rust prevention treatment, for example, in the summer, more rain, high temperature, many owners will choose to stop work for a period of time, because the huge body of the excavator can not be stored in a closed environment such as a garage like a car, so the anti-rust work should be paid special attention.
For example, before the excavator needs to be parked for a long time, the engine antifreeze must be updated and refilled, and must be replaced with the same brand of quality assurance antifreeze, which is to prevent the engine waterway from rusting after a long time of parking.
For example, before stopping, the fuel tank should be filled with oil to prevent the tank from rusting due to long-term storage, air, rain and other corrosion.
4, excavators in the construction process, easy to scratch the left and right butt. When the paint is scratched and peeling, the old driver will repair the paint and spray paint before work to prevent rust and other problems in the scratched parts.
