The Use and Maintenance of Dump Truck Tires

Use of dump truck tires

Mining and fleet vehicles often work in two or three shifts, and drivers or maintenance personnel need to check the tire pressure of all tires once a week. The ideal time to check the tire pressure is before the morning shift. If the tire pressure is 20% lower than the normal tire pressure, it should be considered a serious leak. If a leak occurs, the leak point caused by puncture or cutting should be carefully searched and repaired. If the tire is only underinflated, it should be inflated to the normal pressure value in time. Due to the effect of thermal expansion and contraction, the tire pressure in winter will also decrease, and proper inflation is necessary. Low tire pressure will increase fuel consumption of the vehicle, accelerate abnormal tire wear, and pose risks for safe driving. At the same time, excessive tire pressure will also affect the grip, especially the braking of the vehicle.

Tires with insufficient inflation often cause abnormal deformation, excessive bending, and ultimately shorten the service life of the tire. Additionally, it can cause irregular wear, punctures, and cuts on the sidewall of the tire, which can lead to further problems. Overly high tire pressure can cause crown wear, tire cutting, punctures, tire explosion, and other problems. The tire industry has a saying: "Tire pressure is the life of tires." From this sentence, it can be seen how important tire pressure is to tire life!

Maintenance of dump truck tires

Regarding daily tire checks, it is best to check them regularly every day, or at least 2-3 times a week. When checking wide tires, check whether there are cracks or scratches on the surface of the tire. It is best to wear gloves and reach into the inner sidewall of the tire to check for suspicious signs. Pay particular attention to the sidewall and shoulder of the tire, and promptly repair large-scale wounds or cracks. Oil and other debris should be cleaned promptly.

Before driving out in the morning, it is also necessary to observe the condition of the tires visually. This visual inspection should focus on observing whether there is obvious underinflation and whether there are foreign objects adhering to the tire surface, such as sharp stones or nails. Once discovered, they need to be dealt with promptly. Also, pay attention to the degree of abrasion, mainly by observing the tread wear of the tire. Once the tread has worn down to the safety line, the tire's lifespan has ended, and it must be replaced with a new tire.

In addition to the above inspection items, driving habits also cannot be ignored. In addition to maintaining dump truck tires, drivers also need to pay attention to the driving method during driving. Most mining roads are full of stones and gravel, so it is necessary to avoid sudden acceleration, sudden turning, and sudden braking. Avoid high-speed driving on poor road conditions, such as avoiding sharp stones dropped by vehicles in front, and avoid crushing sharp stones on the roadside when passing narrow mining roads. During parking, avoid scratching obstacles with tires. These actions can cause serious wear and cuts on tires, which can shorten the life of the tire. It can be said that good driving habits have the most direct and effective effect on tire maintenance.

Engineering dump truck tires are important parts of mining and port vehicles, with high load and torque capacity, high adhesion, cushioning performance, durability, and can meet the vehicle's requirements for use in harsh road conditions in mines. These performance requirements are determined by factors such as tire structure, specifications, pattern, materials, and manufacturing processes on the one hand, and they have a close relationship with the site conditions and usage, such as road conditions and the timely inspection and cleaning of jammed stones.
