The running-in period of truck-mounted cranes requires not only maintenance but also fuel economy

When a new truck-mounted crane is purchased, proper maintenance is of utmost importance. During the running-in period, meticulous care is needed to ensure the smooth operation and longevity of the vehicle. The maintenance of truck-mounted cranes during this stage should involve reducing load, strengthening lubrication, paying close attention to operation, and being vigilant in inspection. However, in addition to these essential maintenance measures, for vehicle owners, achieving fuel economy in an environmentally friendly way is also a significant concern. After all, saving fuel not only reduces costs but also contributes to a greener environment. So, how can we achieve fuel-saving effects while using truck-mounted cranes? Let’s explore several important points to consider.

One of the key ways to save fuel is to try to reduce the dead weight of the crane vehicle as much as possible. Increasing the dead weight of the vehicle inevitably leads to a corresponding increase in fuel consumption. When a truck-mounted crane is carrying unnecessary additional equipment that is not essential for the project at hand, it requires more energy to move, resulting in higher fuel usage.

For example, during construction projects, if there are tools or accessories on the vehicle that are not being used immediately, they should be removed. This not only lightens the load but also reduces the strain on the engine and transmission. By carefully evaluating what is truly needed on the vehicle and removing any excess weight, fuel consumption can be significantly reduced.

Imagine a truck-mounted crane with various pieces of equipment that are not in use but still being carried around. The engine has to work harder to move this extra weight, burning more fuel in the process. By removing these unnecessary items, the vehicle becomes more efficient and uses less fuel.

Another important aspect is to try to reduce the fuel consumption per unit load as much as possible. Under the condition that the vehicle’s condition permits, increasing the vehicle’s load capacity to the rated load can be a smart move. Not only does this improve productivity, but it can also significantly reduce the fuel consumption per unit weight.

When a truck-mounted crane is operating at or near its rated load capacity, it is making the most efficient use of its power and fuel. Instead of making multiple trips with lighter loads, maximizing the load can reduce the overall number of trips and, consequently, the amount of fuel consumed.

For instance, if a crane is constantly making short trips with partial loads, it is not only less productive but also wastes fuel. By planning and organizing loads to reach the rated capacity whenever possible, fuel efficiency can be greatly enhanced.

The fuel supply advance angle of the engine plays a crucial role in fuel consumption. When the fuel supply advance angle is too large or too small, the fuel consumption of the engine can increase significantly. Therefore, to ensure the engine has optimal performance, the fuel supply advance angle must be calibrated precisely.

An improper fuel supply advance angle can lead to inefficient combustion and reduced power output. This not only wastes fuel but can also cause engine knocking or other problems. By having a professional mechanic adjust the fuel supply advance angle to the correct setting, the engine can operate more smoothly and efficiently.

For example, if the fuel supply advance angle is too large, the fuel may ignite too early, causing knocking and reduced efficiency. On the other hand, if it is too small, the fuel may not burn completely, resulting in wasted fuel and lower power. By finding the perfect balance, the engine can run at its best and consume less fuel.

Trying to increase the engine compression ratio to the standard value is also an effective way to improve fuel economy. The compression ratio of diesel engines is generally between 16 and 22. Increasing the compression ratio can increase the temperature and pressure at the end of compression, which is highly conducive to the combustion and expansion of the mixed gas. This, in turn, can improve the thermal efficiency of the engine, increase the effective power, and reduce fuel consumption.

To achieve this, specific measures can be taken. Reducing the resistance of the intake system is essential. The filter should be cleaned and maintained in time to ensure that there is enough air entering the cylinder in a timely manner. A clean air filter allows for better airflow, which improves combustion efficiency. Additionally, grinding the valves, replacing the piston rings, and cleaning the carbon deposits in the combustion chamber as needed can also help increase the compression ratio and improve engine performance.

For instance, if the intake filter is clogged, the engine has to work harder to draw in air, reducing efficiency and increasing fuel consumption. By keeping the filter clean and performing regular maintenance on the engine components, the compression ratio can be optimized, resulting in better fuel economy.

Minimizing the resistance and acceleration resistance of the crane vehicle during driving is crucial for saving fuel. High resistance means higher fuel consumption. During construction, paying attention to changes in road conditions and selecting appropriate tire pressure can help reduce fuel consumption.

Uneven road surfaces or obstacles can increase the resistance the vehicle has to overcome, requiring more power and fuel. By choosing the smoothest possible routes and avoiding rough terrain when possible, fuel usage can be reduced. Additionally, maintaining the correct tire pressure is essential. Underinflated tires can increase rolling resistance, while overinflated tires can lead to poor handling and reduced traction.

The transmission ratios of each gear of the vehicle transmission also have a significant impact on fuel consumption. During construction, high-speed gears with a small transmission ratio should be selected as much as possible to save fuel. These gears allow the engine to run at a lower RPM while maintaining a reasonable speed, reducing fuel consumption.

For example, if a truck-mounted crane is driving on a bumpy road with underinflated tires, it will consume more fuel due to the increased resistance. By choosing a better route and maintaining proper tire pressure, fuel consumption can be minimized. Additionally, using the appropriate gears for the driving conditions can further enhance fuel efficiency.

Maintaining a stable and appropriate speed during driving is also an important aspect of saving fuel for the vehicle. Each vehicle has an optimal speed range, known as the economic speed, where it consumes the least amount of fuel. This speed varies depending on the vehicle’s make and model, as well as factors such as load and road conditions.

Driving too fast or too slow can increase fuel consumption. When driving at high speeds, the engine has to work harder to overcome air resistance, while driving too slowly can cause the engine to operate inefficiently. By finding and maintaining the economic speed, fuel consumption can be reduced significantly.

For instance, if a truck-mounted crane is constantly speeding or driving too slowly, it will use more fuel than necessary. By being aware of the vehicle’s economic speed and driving at that speed whenever possible, fuel efficiency can be improved.

In conclusion, during the running-in period of truck-mounted cranes, not only is proper maintenance essential, but also achieving fuel economy is crucial. By following these tips and being mindful of fuel consumption, vehicle owners can save costs, reduce environmental impact, and ensure the long-term performance of their truck-mounted cranes.
