Lightly open and close lids weighing approximately 22 to 50 kgf! The movable hinge and shock absorber mounting base are integrated! Delivery times have been shortened, and prices have become more affordable.
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.

basic information
**Features of YK Balancer S3-45 Model** - Suitable for lids weighing approximately 22 to 50 kgf - Utilizes springs, eliminating the need for electric, pneumatic, or hydraulic power - Lifting force can be freely adjusted according to the weight of the lid - Safety measures include a lid tilt prevention safety pin and shock absorber - Safety and reliability confirmed through repeated opening and closing durability tests and waterproof tests **About the Shock Absorber** When the lid is fully opened, it hits the stopper, causing an impact. The heavier and larger the lid, the greater the impact. The shock absorber mitigates this impact through hydraulic means, enabling safe lid opening and closing operations at heights such as on top of tanks. **Lid Tilt Prevention Safety Pin** By inserting a safety pin into the fully opened lid, it prevents the lid from accidentally tilting, allowing for safe and secure operations. *For more details, please contact us.*
