What Vulnerable Parts Are Recommended To Be Kept On Hand For Long-term Heavy-duty Operations Of Heavy Trucks

In overseas mining areas, mountainous infrastructure, sand and gravel transportation and other scenarios, heavy trucks are in a state of full load, bumpy, and high-intensity operation for a long time, and the speed of wear and tear of vehicle vulnerable parts is much higher than that of ordinary standard load transportation. Many overseas fleets have experienced work stoppages and delays, not due to major vehicle malfunctions, but due to a lack of commonly used vulnerable parts. Minor malfunctions cannot be dealt with in a timely manner, directly affecting the progress of the project. For heavy-duty truck fleets engaged in long-term heavy load operations, keeping high-frequency vulnerable parts in advance is the key to improving attendance and reducing operation and maintenance costs.
Firstly, the vulnerable parts of the braking system rank first in terms of wear and tear under heavy load conditions. Long term climbing, downhill, frequent start stop, extremely fast wear of brake pads and brake drums, frequent accumulation of dust and high temperature attenuation. It is recommended that the fleet keep brake pads, brake cylinders, brake hoses, and brake adjustment arms on hand. Heavy duty vehicles in mountainous areas have a high braking load and a high probability of sudden wear and tear of accessories. Pre stocking can avoid the risk of suspension caused by brake failure and ensure driving safety.
Next is the chassis walking system accessories. Under heavy and bumpy road conditions, steel plate springs, leaf spring bushings, balance shaft rubber sleeves, and shock absorbers are high-frequency consumables. Long term overweight driving of vehicles can lead to aging and cracking of rubber sleeves, as well as fatigue deformation of leaf springs, resulting in body shaking, deviation, and decreased load-bearing capacity. Most overseas construction sites are far away from maintenance stations and have a complete set of rubber sleeves, bushings, and shock absorbers on hand, which can quickly complete maintenance and replacement, and maintain chassis stability.
Tire and wheel hub related accessories are essential. Gravel and sharp slag in mining areas are prone to scratching and puncturing tires, and heavy load driving can also cause loose wheel hub screws and wheel end wear. It is recommended to keep spare tires, wheel hub screws, bearings, valves and other accessories for heavy-duty use. Tire failure is the most sudden and frequent problem on construction sites, which can be replaced and repaired at any time to avoid a single tire failure causing a full day shutdown.
Hydraulic and dump system vulnerable parts are exclusive and essential requirements for dump trucks. Long term lifting and unloading can cause wear and oil leakage of hydraulic cylinder oil seals, oil pipes, sealing rings, and limit valves. Once the hydraulic system is depressurized, the vehicle cannot lift and unload materials, directly losing its operational capability. It is recommended to keep a complete set of hydraulic seals, high-pressure oil pipes, and hydraulic filters on hand for large fleets, and replace them as needed to avoid delaying the construction progress.
Finally, there are vulnerable parts for engine maintenance. Under heavy and high load conditions, the engine's intake and fuel supply loads are greater, resulting in faster losses of air filters, oil filters, diesel filters, and belts. The construction site has large dust and uneven oil products, and the filter element is prone to clogging. Keeping the three filters and transmission belt in advance and replacing them on time can effectively protect the engine, reduce problems such as high temperature, insufficient power, and carbon deposition.
In summary, the core of heavy-duty truck operation and maintenance is to reserve and prevent replacement in advance. Standing brake components, chassis rubber sleeves, hydraulic accessories, tire consumables, and engine filters are five types of vulnerable parts that can minimize the probability of downtime. As an export heavy truck manufacturer, we support the use of localized commonly used vulnerable parts lists and accessory packages with the vehicle, helping overseas fleets to maintain stable attendance and operate efficiently.
