Working hours have been overwhelmingly shortened! The work efficiency of bolt fastening in maintenance has also been optimized to the highest level.
Here is a case study of Kawasaki Heavy Industries, Ltd. that adopted Nord-Lock products. In the company, some bolts used in the compressor and turbine sections of the M7A gas turbine were secured with wire locks to prevent loosening. There were challenges as the effectiveness of the loosening prevention depended on the skill of the workers, leading to low work efficiency. Additionally, there was a risk of wire breakage during operation due to insufficient tightening of the wire. Therefore, our "Nord-Lock washers" were adopted. As a result, not only did the difficulty of the work significantly decrease, but the work time was also overwhelmingly shortened. 【Case Overview】 ■ Customer: Kawasaki Heavy Industries, Ltd. ■ Product: M7A-03D Gas Turbine ■ Adopted Product: Nord-Lock Washer *For more details, please refer to the PDF document or feel free to contact us.
