Next-generation manhole cover with enhanced performance through innovative ideas.
"EVS" is a cast iron cover with a support structure that has evolved by incorporating new ideas to prevent excessive sinking and wobbling of the lid. When a load is applied to the top surface of the cast iron cover, it deforms the contact area between the lid and the frame, preventing excessive sinking and wobbling of the lid. Performance can be achieved by changing the shape of the contact area without significantly altering the basic shape of the steep slope receiving structure. 【Features】 ■ Utilizes metal deformation ■ Utilizes steep slope receiving structure *For more details, please contact us or download the catalog.
