The YK Balancer is a spring-loaded hinge that allows for easy manual opening and closing of manhole covers. We have recently made improvements to one of our lineup products, the "YK Balancer S2-45 model." As a result, starting around June 2021, we will change its name to the "YK Balancer S3-45 model." 【Improvement Details】 <Integration of movable hinge and shock absorber mounting base through precision casting> ◎ Previously, the installation of the shock absorber required welding, but this is no longer necessary, reducing the delivery time to one week. Additionally, we have achieved cost reduction through a decrease in labor hours, making on-site installation of the shock absorber possible. ◎ The existing models, S1-45 and S2-45, can also have shock absorbers installed by replacing the movable hinge. Other components can also be replaced without any issues. *For more details about the product, please contact us. This name change is intended to distinguish between the presence or absence of improvements and will not cause any inconvenience or issues regarding the replacement of parts for previously delivered products.
