In a large - scale construction site in Canada, which is responsible for building a highway, an EX8000 - 7 excavator that was in charge of earth - moving work suddenly had a malfunction. The operator found that when the excavator was trying to lift the bucket to dig the soil, the lifting speed was significantly slower than usual, and even when the bucket was loaded with a small amount of soil, it was difficult to lift it. At the same time, the hydraulic system of the excavator emitted a faint overheating smell, and the pressure gauge on the operation panel showed that the hydraulic pressure was much lower than the normal value.
The on - site maintenance team immediately carried out an inspection. They first checked the hydraulic oil pipeline for leaks, but found no obvious oil seepage. Then they disassembled the hydraulic filter and found that there were some metal debris in it, which indicated that there might be wear and tear inside the hydraulic components. After further disassembly and inspection of the hydraulic system, they finally confirmed that the hydraulic pump of the excavator had been seriously worn. The internal rotor and stator of the pump were damaged, resulting in insufficient oil supply and low pressure in the hydraulic system, which affected the normal operation of the excavator.
The construction period of the highway project was very tight, and the shutdown of the EX8000 - 7 excavator would directly delay the progress of the earth - moving work, which might lead to the failure to complete the project on schedule. The construction company contacted the original equipment manufacturer (OEM) of the excavator as soon as possible. The OEM said that the original hydraulic pump needed to be produced in their factory in Germany and then shipped to Canada, and the entire delivery cycle would take at least 8 weeks. In addition, the price of the original hydraulic pump was extremely high, which would bring a heavy economic burden to the construction company. The construction company was in a difficult situation: waiting for the original hydraulic pump would cause huge losses due to project delay, while choosing untested alternative products might have compatibility problems and affect the service life of the excavator.
Solution:
In order to solve the problem as soon as possible, the procurement manager of the construction company began to look for reliable hydraulic pump manufacturers on international industrial e - commerce platforms. After browsing a large number of product introductions and customer reviews, he noticed KICAN Company, which has rich experience in producing hydraulic components for large - scale engineering machinery. The manager quickly contacted KICAN's online technical support team through the official website and provided detailed information, including the model of the excavator (EX8000 - 7), the technical parameters of the original hydraulic pump, the current fault phenomena, and the urgent demand for the project to resume work.
After receiving the information, KICAN's technical team immediately started working. They first conducted a comprehensive analysis of the technical parameters of the original hydraulic pump of the EX8000 - 7 excavator and combined with the working conditions of the excavator at the Canadian construction site (such as long - time continuous operation, large load during earth - moving, and large temperature difference between day and night), they formulated a targeted customized hydraulic pump solution.
This customized hydraulic pump from KICAN has many outstanding advantages. In terms of compatibility, it is completely consistent with the installation dimensions, oil inlet and outlet interfaces, and control methods of the original hydraulic pump of the EX8000 - 7 excavator. The construction company's maintenance personnel can directly replace it without modifying any part of the excavator's hydraulic system, which greatly saves the installation time. In terms of cost, compared with the original hydraulic pump, KICAN's customized product is 35% cheaper, which effectively reduces the maintenance cost of the construction company. In terms of quality, KICAN uses imported high - precision bearings and wear - resistant sealing materials for the hydraulic pump. The core components are processed by CNC machine tools with high precision, which ensures the stability and durability of the product. The hydraulic pump has also undergone 100 - hour no - load test and 50 - hour load test to ensure that it can adapt to the harsh working environment of the Canadian construction site. In terms of delivery speed, relying on its integrated production chain (covering raw material processing, component manufacturing, product assembly and quality inspection), KICAN can speed up the production process. The technical team promised that the customized hydraulic pump would be delivered to the Canadian construction site within 3 weeks.
The construction company was very satisfied with KICAN's customized solution after evaluating it. They immediately signed a purchase agreement with KICAN. During the production process, KICAN regularly sent the production progress photos and test data of the hydraulic pump to the construction company, so that the construction company could keep track of the product status at any time.
Three weeks later, the customized hydraulic pump from KICAN arrived at the Canadian construction site on time. With the remote guidance of KICAN's technical team (through online video conferences to explain the installation steps and precautions in detail), the construction company's maintenance personnel successfully installed the hydraulic pump on the EX8000 - 7 excavator in just 4 hours.
When the excavator was restarted, the operator was pleasantly surprised to find that the bucket lifting speed returned to the normal level, and even when the bucket was loaded with a large amount of soil, it could be lifted smoothly. The pressure gauge on the operation panel showed that the hydraulic pressure was stable within the normal range, and there was no longer any overheating smell from the hydraulic system. In the following two months of continuous work, the EX8000 - 7 excavator performed excellently. It not only completed the daily earth - moving task ahead of schedule but also maintained stable operation even in the case of low temperature in the early morning and high temperature at noon.
The project manager of the construction company said excitedly: "KICAN's customized hydraulic pump has solved our big problem! If we wait for the original hydraulic pump, we will definitely miss the construction period, and the loss will be incalculable. But KICAN's product not only has fast delivery speed but also excellent quality. The excavator's working efficiency is even higher than before the fault. Moreover, the price is much lower than the original one, which has saved us a lot of money. We are very satisfied with this cooperation."
The operator of the excavator also shared his experience: "After replacing the hydraulic pump from KICAN, the excavator's operation becomes much smoother. The response of the bucket action is very fast, and there is no lag phenomenon. Even after working for a whole day, the hydraulic system does not feel overheated, and the operation comfort has been greatly improved. I think this hydraulic pump is even better than the original one."
In addition, the maintenance supervisor of the construction company added: "The installation of KICAN's hydraulic pump is very convenient, and the technical team's guidance is very professional. In the past two months, we have not found any problems with the hydraulic pump. The daily maintenance is also very simple, which reduces our maintenance workload. We will definitely recommend KICAN's products to other construction companies we know."
