Heavy Duty Manhole Covers: SELFLEVEL® Concrete Access Assembly by EJ

selflevel manhole cover

SELFLEVEL® heavy duty manhole covers from EJ are engineered specifically to address the key issues associated with road surfaces, such as frost heave or uplift, settling of manhole covers, site deterioration, inclined street surface, and cracking of concrete or asphalt.

Aside from protecting pedestrians and vehicles from the complex subsurface infrastructure, the access assembly is designed to accommodate various movements, keeping a perfect alignment with the road surface.

How Do SELFLEVEL® Heavy Duty Manhole Covers Work?
SELFLEVEL® heavy duty manhole covers are composed of an upper frame, and below-ground guide frame. The surrounding road surface supports the top frame, and allows the frame to move in place, creating a "floating" effect. When installed, SELFLEVEL® movement reaches a maximum 5° angle, while moving with the surface. This "floating" mechanism disperses traffic vibration and shock, thus prolonging the service life of road infrastructure, as well as underground utilities.

EJ incorporates properties to improve reliability and ergonomics, for reduced strain and ease of use. SELFLEVEL® heavy duty manhole covers are equipped with the patented, closed-design EPIC® Pick Bar solution for improved stability and leverage.

The below-ground guide frame facilitates self-centering. It has a multi-functional seal that keeps the top frame centred within the guide frame. The seal also prevents the two frames from coming in contact with one another. Apart from keeping the frames from touching, the multi-functional seal prevents water infiltration and debris from entering the manhole covers.
