On a scorching summer afternoon, the construction site of a highway expansion project was in full swing. The Hitachi 2600 - 7 excavator, a core piece of equipment responsible for excavating the foundation, suddenly "broke down". Tom, the operator who had been operating this excavator for three years, was confused. Just a few minutes ago, he was smoothly digging a large pit, but suddenly, the hydraulic motor of the excavator stopped rotating. He tried to adjust the control lever repeatedly, but the motor only made a weak "hum" sound and rotated at an extremely low speed, which was far from meeting the construction needs.
Tom immediately shut down the machine and reported the situation to the on - site maintenance supervisor, David. David rushed over with the maintenance team. They first checked the hydraulic oil level, which was normal. Then they inspected the hydraulic oil pressure and found that it was lower than the standard value. They suspected that the oil pump might be faulty, so they disassembled and checked the oil pump, but no obvious damage was found. Later, they adjusted the relief valve, but the hydraulic oil pressure still didn't return to normal.
The maintenance team then turned their attention to the hydraulic motor itself. They disassembled the motor and found that some internal parts were severely worn, with obvious scratches on the surface of the rotor and stator, which led to excessive internal leakage. In addition, a small amount of impurities in the hydraulic oil had caused partial blockage of the oil passage inside the motor, and there was a sign of slight jamming between the valve core and the valve sleeve. Even after the maintenance team cleaned the oil passage and replaced some small worn parts, the hydraulic motor still couldn't work normally. The project schedule was tight, and the failure of the Hitachi 2600 - 7 excavator made the entire construction progress stagnant. The project director, Sarah, was worried day and night, knowing that every day of delay would bring huge economic losses to the company.
Solution:
Online Contact with KICAN Company and Its Customized Hydraulic Motor Solution
Under the urgent situation, Sarah decided to seek help from professional hydraulic equipment companies. She asked her assistant to search for well - known companies in the field of hydraulic motors online. After comparing multiple companies' product introductions and customer reviews, they focused on KICAN Company. The company's official website showed that it had more than 15 years of experience in R & D and production of hydraulic motors, and had provided customized solutions for many well - known construction machinery brands.
Sarah immediately sent an online inquiry to KICAN Company, detailing the fault situation of the Hitachi 2600 - 7 excavator's hydraulic motor, including the phenomena of non - rotation and low speed, the inspection and maintenance work done by the on - site team, and the suspected causes such as insufficient hydraulic oil pressure and severe internal wear of the motor.
Within half an hour, the technical team of KICAN Company replied. They held an online video conference with Sarah and the on - site maintenance team, carefully asked about the specific parameters of the excavator and the working environment of the hydraulic motor, and analyzed the fault reasons again based on the provided information. Finally, they concluded that the internal structure of the original hydraulic motor had been seriously damaged, and simple maintenance could not restore its normal performance, so a new hydraulic motor needed to be replaced.
Considering the special working conditions of the Hitachi 2600 - 7 excavator (frequent heavy - load operations and long working hours), the technical team of KICAN Company proposed a customized hydraulic motor solution. This customized hydraulic motor adopts high - strength alloy materials for key parts, which can effectively improve wear resistance and service life. At the same time, it is designed according to the installation dimensions and interface parameters of the original brand hydraulic motor, ensuring perfect replacement without modifying the excavator's original hydraulic system.
In terms of price, compared with the original brand hydraulic motor, KICAN's customized product is 30% lower, which greatly reduces the company's equipment replacement cost. In terms of quality, KICAN Company has a complete quality control system. From the purchase of raw materials to the final product inspection, every link is strictly controlled, and the customized hydraulic motor has passed 100 hours of continuous operation testing to ensure stable performance.
In addition, relying on its integrated production chain (covering R & D, production, assembly and testing), KICAN Company can shorten the production cycle. After confirming the order, the production department started production immediately, and the customized hydraulic motor was completed and delivered to the construction site in only 5 working days, which was much faster than the 15 - day delivery cycle of the original brand.
When the customized hydraulic motor from KICAN Company arrived at the construction site, the maintenance team immediately carried out the installation work. With the help of the installation guide provided by KICAN's technical team, the entire installation process was completed in only 2 hours.
When Tom restarted the Hitachi 2600 - 7 excavator, he was surprised to find that the hydraulic motor rotated flexibly, and the rotation speed was stable and reached the standard value. He carried out a series of operations such as digging, lifting and rotating, and the excavator responded quickly and smoothly, without any lag or abnormal noise.
Sarah was very satisfied with the effect. She said: "KICAN Company's customized hydraulic motor has solved our urgent problem. Not only is the delivery speed fast, but the product quality is also excellent. After using it for a month, the excavator has been working continuously, and the hydraulic motor has never had any problems. The lower price also saves us a lot of money. This is a very cost - effective cooperation."
Tom also shared his usage experience: "The excavator with the new hydraulic motor is more powerful than before. When digging hard soil, it can easily break through without the previous situation of insufficient power. The operation is also more stable, which makes my work efficiency improve by nearly 20%. I no longer have to worry about the hydraulic motor suddenly failing during work."
Up to now, the Hitachi 2600 - 7 excavator with KICAN's customized hydraulic motor has been working stably for three months, ensuring the smooth progress of the highway expansion project. The company has also signed a long - term cooperation agreement with KICAN Company, and will give priority to choosing KICAN's products for future hydraulic equipment replacement and maintenance.
