In this article, we will review the maintenance tips for road construction and mining machines such as excavators, mini shovels, loaders, graders, bulldozers, trucks, shovels, etc.
In summer, we definitely see a lot of heat, this is just It is not the workers who suffer under the heat. Extreme temperatures can also affect your equipment and heavy machinery, leading to overheating and even complete failure. In the following, we refer to 12 steps to maintain our machines:Inspection on a regular basis
Out of the discussion of maintenance only in the summer season, you should pay attention to the things that make your car perform better in other seasons. Things like:
* rubber (which can expand in too much heat), * Checking fasteners * Brake check * Level of liquids and fluids such as water and oil * Check for leaks * Regular lubrication * General cleaning of equipmentClean the radiator
Dust, dirt, pollen and other particles can form a thick layer on your machine's radiator, preventing the heat exchange needed to keep the engine and other systems at the right temperature. Clean the radiator of your backhoe, loader, bulldozer and grader regularly by blowing air (you can use a water hose to direct particles down the radiator).
Keep the surface of the cooling liquids
At the beginning of the summer season, change your coolant or radiator water to make sure there is no sludge or debris inside the system and check your cooling hoses. Then, be sure to check each unit's antifreeze/coolant (AF/C) level at the start of each day during the summer, using the fluids specified by the OEM in the owner's manual. An unbalanced ratio of coolant to water can cause a variety of engine problems, so maintain the proper level to keep your equipment cool this season.
Inspecting fans and clamps
Heavy equipment often moves slowly or stays completely in place, meaning natural airflow through the engine can be non-existent or very poor. To accommodate this fact, many equipment have large fans that blow air through the car's cooling system. At the beginning of summer and regularly throughout the season, inspect the fan and its fasteners to ensure they are working properly and protecting your machinery from extreme heat.
Recharge batteries
With many other components that are affected by the summer heat, such as tire inflation and cooling, it is easy to forget about the mining machinery battery. However, extreme heat can cause batteries to malfunction. Avoid possible battery problems in the summer by keeping the batteries and electrolytes charged at the right level.
Avoid working in the hottest hours
The peak hours of the day in the middle of summer are not only dangerous for your workers, but the operation of the equipment during this time can create potential risks for your road construction machinery.
Do not work more than the capacity of the device
On summer working days, most of the time your machines reach the maximum working capacity. Each part in road construction and mining machinery is designed to withstand a certain pressure. If you force the machines to work extra; For example, apply additional pressure to them, this pressure will exceed the breaking point of the part and the parts will go out of the tolerance threshold. This action greatly reduces the useful life of the parts. For example, your excavator spare parts may fail prematurely if used beyond their capacity. In any case, especially during extreme heat, only use your heavy equipment to the extent of your desired capacity.
Check the A/C system or the same air conditioner
Before the summer heats up, check the cooling system and repair your car's A/C systems if necessary. Then, every week during the season, do a quick check to make sure your cabin air intake filters are clean. During operation, avoid having the door open or the window down when running the air conditioning system, as this will cause more pressure to enter the cooler system.
Look the displays regularly.
When working in the hottest summer heat, pay close attention to the displays of your road construction and mining machinery and pay special attention to any temperature indicator. These displays are often the first indication that equipment is approaching overheating. If you need to cool down, stop working immediately and move your device to the shade if possible.
Leave an extra cooling time
If your machines work all day in extreme heat, give your machine a few minutes to cool down after a few hours of work. The turbocharger of the device rotates at a very high speed, especially when the machines have worked hard and makes it quite hot. In order for the oil to continue to supercharge at idle, the engine must be running. If you turn off the engine too quickly, you can damage the engine and the supercharger.
Re -fill the fuel tanks and deflect
Be sure to refill the fuel and diesel exhaust fluid (DEF) tanks after the equipment is shut down. At the end of a day's work, these fluids can be very hot, and the heat can cause moisture to stick to the inside of the fuel tank as dew, especially in the humid summer months. If even a small amount of water mixed with your fuel reaches the injector system, it will cause serious damage to the system. Avoid these issues by refilling your tanks at the end of each summer day.
Keep in the shade
As soon as the machines have cooled down and done the necessary checks, it is time to rest and park it. If you can expose your device to direct sunlight, that's great, but if you can't, try to create a good shade on your car with a cloth or cover.
What you are doing is one of the tough jobs And it gets even harder under the hot summer sun. This heat can also affect your machinery, so be sure to follow these summer machinery maintenance tips to optimize their performance throughout the season.
