Keep five parts of the truck-mounted crane clean

The proper maintenance of a truck-mounted crane is crucial for ensuring its optimal performance and longevity. There are numerous aspects to consider when it comes to maintaining these powerful machines, and while vehicle owners may sometimes overlook certain details, taking care to keep specific parts clean can go a long way in reducing the need for repairs and extending the service life of the truck-mounted crane. In this article, we will explore the five key areas that should be kept clean for effective maintenance.

Most of the operations of truck-mounted cranes take place outdoors and in the wild, often in environments where they are exposed to dust, sand, and water. As a result, the body of the crane is highly susceptible to getting dirty. Dust and sand can accumulate on the surface of the vehicle, not only making it look unappealing but also potentially causing damage over time. If left unchecked, these contaminants can lead to rusting, which can weaken the structural integrity of the crane and reduce its lifespan.

To prevent rust and keep the body in good condition, it should be wiped frequently. Regular cleaning can remove dirt, dust, and other debris before they have a chance to cause damage. Use a soft cloth or sponge and a mild detergent to gently clean the surface of the crane. Avoid using abrasive cleaners or brushes that could scratch the paint.

In addition to regular wiping, if necessary, repainting can be a good option to prevent rust. When the paint on the body of the crane becomes damaged or worn, it exposes the metal underneath to the elements, increasing the risk of rust formation. By repainting the affected areas or the entire crane, you can provide a protective barrier against rust and keep the vehicle looking good.

For example, imagine a truck-mounted crane working on a construction site. The dust and debris kicked up by heavy machinery can quickly cover the crane’s body. If not cleaned regularly, this dust can settle into crevices and scratches, attracting moisture and leading to rust. By taking the time to wipe down the crane after each use and considering repainting when needed, the owner can ensure that the body remains in good condition and is less likely to require expensive repairs due to rust damage.

The engine cooling system of a truck-mounted crane plays a vital role in maintaining the proper operating temperature of the engine. If the cooling water becomes contaminated, it can lead to a variety of problems, including overheating, engine damage, and reduced performance. Therefore, it is essential to keep the cooling water clean.

For the engine cooling water, it is best to use soft water. Soft water is less likely to contain minerals and impurities that can cause buildup and corrosion in the cooling system. Examples of soft water sources include snow, rainwater, treated tap water, and clean well water. These sources are generally free from the hard minerals found in some untreated water sources, which can cause problems over time.

When cleaning the cooling system, adding 1% caustic soda and 0.5% kerosene according to the proportion of water volume can help remove deposits and contaminants. Caustic soda is a strong alkaline substance that can dissolve rust and other deposits, while kerosene can help loosen and remove grease and oil. However, it is important to use these substances carefully and follow proper safety procedures, as they can be hazardous if not handled properly.

For instance, if the cooling water in a truck-mounted crane‘s engine becomes contaminated with dirt and minerals over time, it can lead to reduced cooling efficiency and potential engine damage. By using soft water and periodically cleaning the cooling system with caustic soda and kerosene, the owner can ensure that the engine remains cool and operates smoothly.

The engine of a truck-mounted crane requires a steady supply of clean air to operate efficiently. When the engine is running, the cylinder inhales a large volume of air per minute, typically 2 to 4 cubic meters. If the air entering the cylinder is dirty or contaminated, it can cause a variety of problems, including reduced performance, increased fuel consumption, and engine damage.

To ensure that the air entering the cylinder is clean, the air filter must be strengthened for inspection and cleaned regularly. The air filter acts as a barrier, trapping dust, dirt, and other contaminants before they can enter the engine. Over time, the air filter can become clogged, reducing its effectiveness and restricting the flow of air to the engine.

Regular inspection of the air filter can help identify when it needs to be cleaned or replaced. Look for signs of dirt buildup, such as a discolored filter or reduced airflow. If the filter is dirty, it can be cleaned using compressed air or a mild detergent. However, if the filter is severely damaged or clogged beyond repair, it should be replaced with a new one.

For example, imagine a truck-mounted crane operating in a dusty environment, such as a construction site or a quarry. The air is filled with dust and debris, which can quickly clog the air filter. If the air filter is not inspected and cleaned regularly, the engine may not receive enough clean air, leading to reduced power output and increased fuel consumption. By paying close attention to the air filter and cleaning or replacing it as needed, the owner can ensure that the engine runs smoothly and efficiently.

Lubricating oil is essential for keeping the moving parts of a truck-mounted crane‘s engine running smoothly. It reduces friction, prevents wear, and helps cool the engine. To ensure optimal performance, it is crucial to keep the lubricating oil clean.

Always pay attention to using clean lubricating oil that meets the standards of the machine. Using low-quality or contaminated oil can lead to engine damage and reduced performance. Check the manufacturer’s recommendations for the appropriate type and viscosity of oil to use.

The filter element of the oil filter should be cleaned regularly. The oil filter removes contaminants from the lubricating oil, but over time, it can become clogged and less effective. For the rotor-type filter, paste a layer of kraft paper of appropriate width and length on the inner wall of the rotor to facilitate the adsorption of dirt under centrifugal force. This can help improve the filtering efficiency and extend the life of the filter.

When cleaning the dirt adsorbed on the filter element, it is best to inflate with an air pump, blow air from the inside to the outside, and scrub with a brush. Never wipe with your hand, as this can introduce contaminants and damage the filter. Use clean calcium-based grease for grease. Do not randomly inject other lubricating oils, as they may not be compatible with the engine and can cause damage.

For instance, if the lubricating oil in a truck-mounted crane‘s engine becomes contaminated with dirt and metal particles, it can lead to increased wear on the engine components and reduced performance. By regularly cleaning the oil filter and using clean lubricating oil, the owner can ensure that the engine is properly lubricated and protected.

At present, most of the engines of truck-mounted cranes are diesel engines. Therefore, the purification of diesel is very important. Contaminated diesel can cause a variety of problems, including reduced performance, increased fuel consumption, and engine damage. There are three methods for diesel purification.

The first method is to let the purchased diesel stand and settle for more than 96 hours. This allows any dirt, water, and other contaminants to settle to the bottom of the container, leaving cleaner diesel on top. When refueling, draw from the top layer of diesel to ensure that the fuel entering the engine is as clean as possible.

The second method is to add a funnel with a filter screen and then a layer of silk cloth when refueling. The filter screen and silk cloth can trap small particles and impurities, preventing them from entering the fuel tank and engine. Regularly clean or replace the filter screen and silk cloth to ensure their effectiveness.

When taking oil from the oil drum, take a filter and wrap a layer of silk cloth or mimeograph paper on the outside. This can further filter the diesel and remove any contaminants. The filter should be cleaned or replaced regularly to maintain its filtering efficiency.

For example, if contaminated diesel is used in a truck-mounted crane‘s engine, it can clog the fuel injectors and filters, leading to reduced power output and increased fuel consumption. By purifying the diesel using these methods, the owner can ensure that the engine receives clean fuel and operates smoothly.

These five points above are worthy of understanding and learning by vehicle owners. Keeping these five parts of the truck-mounted crane clean is the best maintenance for the truck-mounted crane. By taking the time to clean and maintain these key areas, vehicle owners can reduce the risk of breakdowns and repairs, extend the service life of their truck-mounted cranes, and ensure that they operate safely and efficiently. Whether it’s wiping down the body, keeping the cooling water clean, ensuring clean air intake, maintaining clean lubricating oil, or purifying the fuel, each step is essential for the proper care and upkeep of these important machines.
