"Expander System" completely prevents wear of the movable part pin hole.
Complete prevention of deformation and cracking due to pinhole wear. An all-around solution with a unique expansion mechanism.
Not only bucket pins and attachment pins, but also wear occurring in the pin holes of movable parts such as the arms of construction machinery, particularly the phenomenon where pin holes become oval-shaped, is a source of concern for many people. For manufacturers, this increases maintenance costs, which are a quality indicator of the machine, and shortens the product lifespan. For machine users, it leads to chronic issues with high maintenance costs and opportunity losses (downtime) due to repair periods when the machine becomes unusable. The benefits of the Expander System are that it can be used semi-permanently and contributes to improving machine quality by extending the product lifespan, while also significantly reducing running costs and maintenance time. The Expander System is already widely adopted by leading construction machinery manufacturers, including Japanese companies, and has passed a continuous practical durability test of 60,000 hours at Volvo Construction Equipment without compromising any functionality. Additionally, all Expander System products come with a lifetime warranty, guaranteeing the product's functionality until the first removal.
