Case studies
Provision of low maintenance cost gearbox for a power plant
Summary
- After the events of 3.11, we perceived the strain on electricity supply as a challenge that our company needed to address. We accurately understood our customers' challenges of significant maintenance costs associated with aging gear mechanisms and achieved problem resolution at minimal cost. Leveraging our strength in load testing, ISHIBASHI repeated the process until satisfied, thereby mitigating risks for both our customers and ourselves. This became a landmark case in our company's history.

Issues and background
Due to the shutdown of the whole nuclear power plants caused by the earthquake in 2011, the old coal-fired thermal power plants were forced to operate at full capacity, leading to extremely high maintenance costs associated with its structure. Electric power companies were facing the challenge of providing a stable supply of electric power under extremely severe conditions.

Initiatives to strive to solve issues
The original design was composed of parts that required special production equipment. This meant that maintenance was only possible on a limited number of sections and costs remained high. We were able to offer the new gearboxes based on modern design at a cost equivalent to the cost of one session of maintenance, with significantly reducing the potential cost of maintenance in the future.

Results and future developments
In the verification process, the company applied its various types of load testing equipment to enhance the product quality, together with dynamic and static tests such as 300% overload element tests.
This is a project to solve social issues that was able to contribute to a socially important power generation business by boldly and enthusiastically facing risks, while breaking free from the restriction of self-estimation.
Voice of customer
ISHIBASHI removed the "restraint" of self-limitation and, instead of merely responding to requests, we sought to exceed our customers' expectations, proposing and working towards outcomes beyond their imagination. This later became the catalyst for deriving our company's business mission: "Challenging the social issue as primal business," symbolizing our commitment to addressing difficulties alongside our customers.
