The Inventory Of Card Vulnerable Parts Should Be Classified According To The Operating Conditions

Many overseas heavy-duty truck fleets have a habit of uniformly purchasing general vulnerable parts when stocking up, without distinguishing between operating conditions. Some parts have accumulated inventory and are idle, and there is a shortage of core essential parts. When encountering vehicle failures, they can only stop work and wait for replenishment, which seriously affects transportation and construction efficiency. The loss parts and speed of heavy-duty trucks in different operating scenarios vary greatly. Only by distinguishing the vulnerable parts inventory list according to operating conditions can the operation and maintenance costs be accurately controlled and improved. The attendance rate of vehicles can be increased. The four most common overseas operating conditions are plain long-distance logistics, mountainous steep slope transportation, mining areas, and heavy load engineering construction sites. The key points of vulnerable parts loss corresponding to each are completely different. The logistics vehicles on the plain long-distance main line cruise at a constant speed for a long time, the road surface is flat and bumpy, and the chassis rubber sleeve steel plate suspension loss is low During long-distance driving, the tires wear evenly but the risk of tire blowouts is high. Lighting accessories, wheel hub bearings, and braking consumables belong to the high-frequency rigid demand category. The focus of fleet stocking is on the three filter belt tires, wheel hub small parts, and conventional brake accessories. There is no need to store a large amount of chassis heavy-duty accessories to avoid inventory waste. The maximum loss of vehicles in mountainous areas is concentrated in the braking system and power system. Frequent braking on long downhill slopes can easily cause rapid wear of brake pads and brake drums. Brake thermal attenuation problems occur frequently. Climbing conditions increase engine torque load, clutch pads, and transmission vulnerable parts. The loss speed of the gearbox is much faster than that of plain vehicles. At the same time, bumpy road conditions in mountainous areas accelerate the aging and cracking of the chassis rubber sleeve and balance shaft liner. Mountain fleets stocking must prioritize thickening brake accessories, power transmission accessories, and chassis buffering accessories to ensure the safety and The road surface is full of gravel and dust, and the overall wear and tear is the most comprehensive. The chassis system, hydraulic system, tire system, and wear and tear are the most severe. The dump truck type, high-frequency lifting and unloading, hydraulic oil seal, high-pressure oil pipe, and sealing ring are prone to oil leakage and failure. The gravel road surface is easy to prick the tire, causing tire surface damage. Heavy load bumps can lead to frequent damage to steel plate spring shock absorbers and frame connectors. This type of working condition requires a complete set of heavy-duty vulnerable parts to be reserved, with a focus on thickening the chassis accessories, hydraulic consumables, wear-resistant tire accessories, and ordinary urban short distance transportation working conditions. The vehicle starts and stops frequently but without heavy load. There is no need to reserve heavy-duty special accessories, which are concentrated in basic maintenance accessories and conventional brake parts. There is no need to reserve heavy-duty special accessories. Many overseas fleets commonly have stocking misconceptions, either all universal The sentence is: Reducing inventory pressure, lowering operation and maintenance expenses, and being able to handle vehicle failures in a timely manner to avoid downtime and work errors. Overseas heavy-duty truck operation and maintenance must abandon unified stocking thinking in order to save money efficiently. Based on the road conditions, load intensity, and operating environment, a list of vulnerable parts must be developed to accurately match working conditions and requirements, making parts reserves more scientific and in line with the actual operational needs of the fleet, comprehensively improving the stable attendance ability of the fleet.
