How to maintain small-tonnage truck-mounted cranes in rainy seasons?

As the Dragon Boat Festival in the lunar calendar approaches, the weather doesn’t follow the expected pattern of a hot climate. Instead, the sudden arrival of the rainy season frequently disrupts the warmth. In this rainy season, various engineering vehicles, including small-tonnage truck-mounted cranes, require special attention when it comes to maintenance. Neglecting proper care during this time can lead to serious consequences that one must bear at their own risk. Today, the author will provide a detailed guide on maintaining small-tonnage truck-mounted cranes in the rainy season. There are four key points that demand your attention.

Lubricating oil plays a crucial role in the smooth operation of a small-tonnage truck-mounted crane‘s engine. After the lubricating oil has been in use for a certain period, several factors, such as air oxidation and contamination, can cause its quality to deteriorate. As a result, it gradually loses its effectiveness in providing lubrication and protection to the engine. Therefore, it is extremely necessary to replace the lubricating oil in a timely manner according to the changing seasons.

During the rainy season, the operating environment of the truck-mounted crane can become more challenging. Moisture and humidity in the air can accelerate the degradation of lubricating oil. If the oil is not replaced when needed, it can lead to increased friction between engine components, reduced engine efficiency, and even potential damage to the engine.

For example, imagine the engine of a small-tonnage truck-mounted crane running on old and degraded lubricating oil during the rainy season. The increased moisture in the air can cause the oil to become less effective in separating the moving parts of the engine. This can result in excessive wear and tear, reduced power output, and potentially lead to engine breakdowns.

To ensure the proper functioning of the engine, it is important to choose the right type of lubricating oil for the rainy season. Consider oils that have good resistance to moisture and oxidation. Consult the vehicle’s manual or a professional mechanic to determine the most suitable lubricating oil for your specific truck-mounted crane model. Regularly check the oil level and condition, and replace the oil as recommended by the manufacturer.

Tire pressure is a critical factor in the safe and efficient operation of a small-tonnage truck-mounted crane. According to tests, for every 10°C increase in temperature, the tire pressure will increase by about 7-14 kpa. Therefore, car owners must pay close attention to the changes in tires as the ambient temperature fluctuates. In the rainy season, when the temperature drops, it is advisable to properly inflate the tires. On the other hand, during summer when the temperature rises, it may be necessary to release some air from the tires to maintain the appropriate pressure.

Proper tire pressure ensures good traction, stability, and fuel efficiency. In the rainy season, the roads can be slippery due to the presence of water. If the tire pressure is too low, it can reduce the contact area between the tires and the road, leading to decreased traction and an increased risk of skidding. On the other hand, if the tire pressure is too high, it can make the tires more rigid and less able to conform to the road surface, also increasing the risk of accidents.

For instance, suppose a small-tonnage truck-mounted crane is operating on tires with incorrect pressure during the rainy season. If the tires are underinflated, the vehicle may have difficulty in maneuvering on wet roads, and it may take longer to stop, increasing the likelihood of collisions. Conversely, if the tires are overinflated, they may be more prone to punctures and may not provide sufficient shock absorption, leading to a bumpy ride and potential damage to the vehicle’s components.

Regularly check the tire pressure using a reliable tire pressure gauge. Adjust the pressure according to the manufacturer’s recommendations and the current weather conditions. Also, inspect the tires for any signs of damage, such as cuts, bulges, or uneven wear. Replace damaged tires promptly to ensure the safety of the vehicle and its occupants.

In spring, the wind is often strong and dry, which can cause a significant amount of blowing sand and dust. As a result, the surface of air conditioning ducts and evaporators can accumulate excessive dust and impurities. Over time, this long-term accumulation can lead to the formation of a large amount of bacteria, which poses a certain threat to the health of drivers and occupants in the vehicle. In the rainy season, it is essential to take out the air filter and clean it thoroughly.

The air filter is responsible for filtering out dust, pollen, and other contaminants from the air entering the vehicle’s engine and cabin. If the air filter is clogged or dirty, it can restrict the flow of air, reducing engine performance and fuel efficiency. In addition, it can also lead to poor air quality inside the cabin, causing discomfort and potential health issues for the occupants.

For example, imagine a small-tonnage truck-mounted crane with a dirty air filter operating in the rainy season. The restricted air flow can cause the engine to work harder, consuming more fuel and producing less power. At the same time, the dirty air filter may not be able to effectively filter out moisture and contaminants from the air, leading to mold growth and a musty smell inside the cabin.

To clean the air filter, carefully remove it from the vehicle according to the manufacturer’s instructions. Use a gentle stream of compressed air or a soft brush to remove the dust and debris. If the filter is extremely dirty or damaged, consider replacing it with a new one. Regular cleaning and maintenance of the air filter can help ensure proper engine performance and a healthy cabin environment.

Not only private cars but also small-tonnage truck-mounted cranes need proper paint maintenance. In the rainy season, a large amount of rainwater can pose a significant threat to the vehicle’s paint. Rainwater is often acidic, and if the vehicle is exposed to rainwater for an extended period, the car paint of the truck-mounted crane can be slowly corroded.

Corrosion of the paint can not only affect the appearance of the vehicle but also reduce its resale value. Moreover, it can expose the underlying metal body to further damage, such as rusting. Therefore, in the rainy season, car owners should try to place the truck-mounted crane in a place without rainwater. If it is inevitably exposed to rainwater, wipe it clean as soon as possible to protect the car paint.

For instance, if a small-tonnage truck-mounted crane is left outdoors in the rain for a long time without proper protection, the acidic rainwater can gradually eat away at the paint, leaving unsightly marks and potentially causing the paint to peel off. This can lead to rust formation on the metal body, weakening the structural integrity of the vehicle.

To protect the paint, consider applying a wax or sealant to the vehicle’s surface before the rainy season. This can create a protective barrier against rainwater and other environmental contaminants. If the vehicle gets wet, wipe it down with a clean, dry cloth as soon as possible to remove any moisture. Avoid using harsh chemicals or abrasive materials when cleaning the vehicle, as these can damage the paint.

In conclusion, proper maintenance of small-tonnage truck-mounted cranes in the rainy season is essential for ensuring their safe and efficient operation. By paying attention to these four key points – replacing suitable lubricating oil, adjusting tire pressure, cleaning the air filter, and maintaining the paint – car owners can prolong the lifespan of their vehicles and reduce the risk of breakdowns and accidents. Remember to follow the manufacturer’s recommendations and consult a professional mechanic if you have any doubts or concerns. With proper care and maintenance, your small-tonnage truck-mounted crane can serve you well even in the challenging rainy season.
