The excavator goes through the rainy season, and slight carelessness will affect the condition and depreciation of the machine. This page will describe the matters needing attention of excavator in rainy days.
1. The vehicle body shall be cleaned in time
Combined with machine construction sites, most of them are in a harsh environment of dust and flying sand. After heavy rain, they will not be clean as new, and even full of dirt. In particular, some important structural components, such as bucket oil cylinder, have long-term residual dirt and dirt, but can not be thoroughly cleaned, so the probability of oil seal damage is very high, which will lead to cylinder pulling, oil cylinder discoloration and other faults. Therefore, it is necessary to thoroughly clean important structural components in time after heavy rain.
2. Paint waxing
When selling second-hand mobile phones, the paint is a part of the investigation of many machine owners. Before going through the rainy season, it is still necessary to protect the paint in advance to prevent damage to the paint caused by some acidic components in the rain. The most effective and easy way is to wax the excavator or seal the glaze with high cost but more lasting effect. This investment may not see specific results in the short term, but after a few years, you will find that when other people's machines are old and new, but your own machines are still brand-new.
3. Chassis care
Because the chassis parts are in the situation of rough work and hard work for a long time, their cleaning and rust prevention are very easy to be ignored. Unlike other seasons, the rainy season will bring huge mud problems to the chassis parts due to the uneven road conditions and muddy environment after the rain. Obviously, if there is too much mud, rust, looseness and perforation of screws and other parts related to chassis parts are common disadvantages. Therefore, it is very important to clean the chassis, check whether the screws are loose, and clean the accumulated water and mud, which can not be ignored.
4. The connector is damp
If the first three inspection and cleaning can be delayed, the inspection of the connector must be carried out in time. Once the machine is stopped in rainy season, it will often be weak or more difficult to start, because the ignition system is wet in rainy season. Therefore, before the rainy season, dry towels, newspapers, paper towels and other items should be prepared in advance. Do not rush to start the excavator construction, but wipe the wires, terminals and other positions with dry towels.
In fact, the above points are far from enough. For example, it is necessary to strictly prevent water from entering the air filter element from affecting the air inlet, keep an eye on the position of the oil dipstick to prevent rainwater from mixing into the oil, clean the dirt of the radiator after rain, and pay special attention to the mode and position of shutdown in rainy days.
Therefore, I would like to remind you that the maintenance of excavators is definitely not just the replacement of maintenance parts, and there are many points that need to be paid attention to in the maintenance of excavators all year round. Therefore, every maintenance and precautions of the excavator shall be carefully done, so as to ensure that the price of second-hand machines can be increased on the premise of ensuring that the machines are in good operation.
