How To Extend The Service Life Of Truck Tires in Overseas Construction Site Environments

Overseas mining area infrastructure construction sites, such as sand and gravel transportation, have complex road conditions with multiple gravel pits, muddy bumps, and concentrated road conditions. Truck tires are subjected to high-intensity heavy load impact and friction conditions for a long time. Compared with mainline logistics, tires wear faster and are prone to problems such as puncture, bulging, uneven wear, and shoulder cracking. Many overseas fleet tires wear out quickly and have high replacement frequency. High operating costs are mostly due to the lack of adaptation to the construction site conditions. Proper tire maintenance and standardized operation. Mastering exclusive tire maintenance techniques on construction sites can effectively delay tire aging and wear, greatly extend service life, and reduce fleet material expenses. Firstly, strict control of tire pressure is necessary to adapt to the construction site conditions. Heavy load is concentrated on the basic construction site. Many drivers use the mainline transportation tire pressure standard, which is extremely easy to cause tire damage. High tire pressure will make the center of the tire under single point Stone Road The surface of the tire is prone to bursting, chunking, low tire pressure, excessive sidewall compression deformation, heavy load starting and turning, and easy tearing of the tire shoulder, causing bulging and cracking. Construction site vehicles need to adjust the tire pressure according to real-time load, maintain standard cold tire pressure, balance support and buffering, and avoid various damages caused by high and low pressure. Secondly, standardize construction site driving operations to reduce hard impact. Construction site driving must avoid high-speed driving, sudden starting, sudden braking, sudden turning, construction site road surface gravel, multiple potholes, dense high-speed driving, causing the tire to directly hit the raised gravel and potholes, causing damage to the internal curtain line and burying hidden bulging hidden dangers. Heavy load starting will exacerbate tire slip and wear. Emergency braking will cause local severe friction on the tire surface, resulting in delamination and chunking. Slow and smooth driving at a constant speed can minimize tire hard wear and avoid human error. The rapid wear and tear caused by operation should be cleaned in a timely manner Screening for tread debris, hidden damage, construction site gravel, iron nails, broken stones, steel bars, and residues are easily embedded in the gaps of tire patterns. If not cleaned in time, continuous driving of the vehicle will cause debris to constantly squeeze into the tire body and slowly pierce through the tire layer, resulting in slow air leakage and tread cracking. After daily parking, it is necessary to regularly clean the tire seams and carefully inspect the tread shoulder for small wounds and cracks. If minor damage is found, it should be repaired in a timely manner to avoid the expansion of small damage and the risk of tire scrapThe fourth is to allocate the load reasonably to prevent unilateral uneven loading and unloading of goods on the construction site. Uneven stacking of materials is easy to occur when loading and unloading goods on the construction site, and the center of gravity of the vehicle is offset, which can cause overloading and pressure on one side of the tire. Long term unilateral heavy loading can cause severe tire wear and excessive shoulder wear, greatly shortening the service life. When loading and unloading materials, try to evenly spread the goods to ensure the balance of the vehicle's load and prevent long-term overloading. Overloading is the core cause of premature tire aging, which can directly exceed the tire's bearing limit and accelerate tire deformation and aging. The fifth is to do a good job in tire protection and regular rotation on the construction site. The construction site is muddy, dusty, and mixed with impurities, which can easily corrode the tire rubber. Long term parking on muddy and damp ground can accelerate rubber aging Balancing the degree of tire wear, improving uneven wear, and effectively extending overall service life. Sixth, select construction site specific tires as needed to eliminate the mixing of ordinary tires. Main line lightweight tires have a single thin body and poor impact resistance, which are completely unsuitable for construction sites. They are easily damaged and scrapped due to long-term use in gravel and heavy load conditions. Overseas construction sites must choose heavy-duty wear-resistant tires with thickened body and reinforced shoulders that are suitable for bumpy and gravel conditions to improve resistance to puncture, cracking, and impact. Many overseas fleets have the misconception of reusing vehicles for light maintenance. Tire damage is only replaced without summarizing the problem of adapting to working conditions, resulting in repeated wear and increased operating expenses. For harsh working conditions on overseas construction sites, do a good job in tire pressure control, standardize driving operations, clean up damage in a timely manner, regularly replace and maintain with dedicated working conditions. Tires can minimize tire failure rates, delay aging and wear, effectively Long term consumables replacement costs and downtime losses for a small fleet
