comprehensively inspect the related parts around the engine, replace the aging seal ring, pipeline and other vulnerable parts, and eliminate the hidden danger of secondary failure;
[Customer Background] A logistics transportation company in Shenzhen has 10 Shaanxi Auto Delong M3000E heavy trucks, which are mainly used for short-distance loading and unloading transportation in ports. After one year of use of the vehicles, various problems such as air pump failure, power weakening, transmission shaft fracture, air conditioning abnormality, etc. have occurred one after another. Many repairs still cannot be completely solved. Frequent failures have led to the interruption of fleet transportation, and the accumulated expenditure on trailer and maintenance costs exceeds 100000 yuan, seriously affecting the normal operation of the company, urgently contact Shenzhen Guangheng for bulk solution.

According to the original factory maintenance standards for assembly and debugging, repeated test run to verify the maintenance effect.
[Failure Phenomenon] Of the 10 vehicles, 4 have air pump failures and need to be replaced frequently; the power of 3 vehicles is suddenly weakened during driving, and there are potential safety hazards when driving at high speed; 2 vehicles have problems such as broken transmission shafts and cracks in tire rims; 1 The air conditioner cannot be cooled normally, which affects the driver's driving experience, and some vehicle failures occur repeatedly, and the maintenance cost after the warranty period increases significantly.
maintenance effect] the entire maintenance process took 3 days, which was significantly shorter than the previous 4 days of a single overhaul. After the maintenance is completed, the vehicle starts smoothly, the abnormal engine noise disappears, the power returns to normal, and the fuel consumption returns to normal levels. Shenzhen Guangheng provided a 3-month/5000-kilometer warranty service for this maintenance, and followed up with regular return visits. The vehicle has been running for 6 months without any engine-related failures. Mr. Chen highly recognized the maintenance effect. He not only said on the spot that Shenzhen Guangheng was chosen for subsequent vehicle maintenance, but also recommended a number of fellow car owners to experience the service.
[Diagnosis Process] Shenzhen Guangheng immediately set up a special maintenance team to conduct a comprehensive inspection of 10 vehicles one by one. Combined with the usage scenarios of port transportation (short distance, high frequency start and stop, heavy load), the root causes of the failure were analyzed: first, some vehicles were overloaded, resulting in excessive wear of transmission system, tires and other components; Second, the previous maintenance only dealt with a single fault point and did not conduct a comprehensive investigation of related components; third, the quality of some maintenance parts is not up to standard, resulting in repeated failures.
[Maintenance Plan and Implementation] In response to the needs of the fleet, Shenzhen Guangheng has formulated a comprehensive solution of "batch maintenance + customized maintenance + technical guidance". First, 10 vehicles are specially overhauled in groups, replacing faulty air pumps, transmission shafts, tire rims and other components, and using original genuine parts to ensure maintenance quality. The second is to conduct a comprehensive investigation of the engines, chassis and circuit systems of all vehicles, replace aging wearing parts in advance to eliminate potential failures; The third is to customize a dedicated maintenance plan for the fleet and carry out regular maintenance according to the mileage and usage scenarios of the vehicles to reduce the failure rate. The fourth is to provide daily maintenance training for fleet drivers to guide correct operation specifications and avoid failures caused by improper operation.
[Maintenance Effect] The whole batch maintenance process takes 7 days, and the maintenance and debugging of all vehicles are completed efficiently, and all faults are completely cured. Shenzhen Guangheng provides exclusive after-sales guarantee for the fleet, and arranges special personnel to inspect the vehicles regularly and deal with all kinds of minor problems in a timely manner. In the following three months, the 10 vehicles of the fleet did not have any major failures, the maintenance cost decreased by 60% year-on-year, and the transportation efficiency was greatly improved. The person in charge of the company specially sent a pennant to establish a long-term strategic cooperative relationship with Shenzhen Guangheng.
