Tires are a crucial component of a truck-mounted crane, and their technical conditions directly influence the tractive force, passability, stability, safety, comfort, and economy of the vehicle. Typically, experienced truck-mounted crane users can analyze the causes of abnormal tire wear and adopt corresponding countermeasures to prevent such wear, extend the service life, save costs, enhance the usage efficiency of the truck-mounted crane, and ensure safe operation. Factors like excessive or insufficient tire pressure, overloading operations, poor four-wheel alignment, unskilled driving techniques of the truck-mounted crane driver, inappropriate selection and installation of tires, and damage from external hard objects can all diminish the lifespan of the truck-mounted crane tires. Here are some guidelines for the correct maintenance of truck-mounted crane tires:
First, strictly adhere to the tire inflation standards stipulated by the manufacturer. After inflation, inspect all parts of the truck-mounted crane for any air leakage and regularly check the tire pressure to ensure that the tire pressure of the truck-mounted crane complies with the standards under all circumstances.
Imagine a scenario where the tire pressure is not maintained at the correct level. Overinflated tires can lead to reduced contact with the road surface, affecting traction and braking performance. On the other hand, underinflated tires can cause excessive flexing, increasing heat build-up and accelerating tire wear.
Second, accurately select and install the tires of the truck-mounted crane, and be cautious in using the corresponding inner tubes based on the tire specifications of the truck-mounted crane.
The correct tire size and type are essential for optimal performance and safety. Using the wrong size or incompatible inner tubes can lead to improper sealing, increased risk of blowouts, and compromised handling.
Third, after the truck-mounted crane has been in use for a period, cross or rotate the front and rear tires depending on the different working environments.
This helps to evenly distribute the wear across all tires, maximizing their overall lifespan. For example, in a working environment with more front-wheel stress, regular rotation can prevent the front tires from wearing out prematurely.
Fourth, pay attention to regulating the temperature of the truck-mounted crane tires. When it is detected that the temperature of the tires is extremely high, park the truck-mounted crane in a shaded area and wait for the temperature to drop before resuming operation, etc.
High tire temperatures can weaken the tire structure and increase the risk of failure. Prompt measures to cool the tires help maintain their integrity and performance.
The above are the correct usage and maintenance practices of the tires of the truck-mounted crane during operation. Timely maintenance of the tires of the truck-mounted crane is beneficial for the safe operation of the vehicle, extends its service life, and concurrently saves the maintenance cost of the truck-mounted crane.
Now, let’s explore some additional aspects and considerations for maintaining truck-mounted crane tires:
Regular inspection of the tire tread depth is crucial. Worn treads reduce grip, especially in wet or slippery conditions, increasing the risk of skidding. Tires with insufficient tread depth should be replaced promptly.
Keep an eye out for any signs of damage such as cuts, bulges, or cracks on the tire surface. Even minor damage can compromise the tire’s strength and integrity, posing a potential safety hazard.
When storing the truck-mounted crane for extended periods, it’s advisable to protect the tires from direct sunlight and extreme temperatures. Using tire covers or storing the vehicle in a covered area can prevent UV damage and premature aging.
The type of terrain and road conditions where the truck-mounted crane operates also impact tire maintenance. For instance, frequent operation on rough or unpaved roads might require more frequent inspections and rotations.
Proper alignment and balancing of the tires are not only important for even wear but also for a smooth ride and reduced stress on other components such as suspension and steering systems.
It’s beneficial to keep a record of tire maintenance activities, including dates of inflation checks, rotations, and replacements. This can help identify patterns of wear and predict when maintenance or replacement might be needed in the future.
Finally, training drivers on proper driving techniques such as smooth acceleration, braking, and cornering can minimize the stress on tires and contribute to their longevity.
In conclusion, maintaining truck-mounted crane tires requires a combination of adhering to correct procedures, regular inspections, and awareness of the operating conditions. By taking these measures, the reliability and safety of the vehicle can be enhanced, and potential downtime and repair costs can be significantly reduced.
