A spring-loaded hinge that allows for easy opening and closing of a manhole cover that is more compact and lightweight than our conventional products (S-90, SR-90)!
The "YK Balancer SR2-90 Waterproof Type" is a spring-loaded hinge that allows for easy manual opening and closing of heavy manhole covers for tanks and reaction vessels currently in use. The YK Balancer "S-90, SR-90" will be discontinued in February 2024 and has been replaced by the compact and lightweight "SR2-90." *The consumable "spring case" will continue to be sold. Without a balancer, two people are required to manually open heavy covers, which is dangerous, hard, and time-consuming. In contrast, using this product allows for safe and easy opening of the cover. The lifting force can be freely adjusted according to the weight of the cover. 【Features】 ■ Size 90 type, suitable for covers weighing 80-100 kg ■ Utilizes a spring, eliminating the need for electric, pneumatic, or hydraulic power, and is compact ■ Lifting force can be freely adjusted according to the weight of the cover ■ Safety measures include a cover tilt prevention safety pin and shock absorber ■ Safety and reliability confirmed through repeated opening and closing durability tests and waterproof tests *For more details, please refer to the catalog or feel free to contact us.
