For Heavy Traffic And Vehicles
With a cover weight of 60 lbs and a load rating of 90,000 lbs, the 100% ductile iron class D400 Rexus II Manhole Cover was designed to be lighter and resistant to the most severe usage conditions, including heavy traffic and vehicles.
Ductile Iron Strength
The key to the Rexus II’s strength is ductile iron. Ductile iron’s superior strength-to-weight ratio allows for over 70% weight savings compared to cast-iron designs Independently tested by a U.S. facility, the Rexus II can withstand an average load of 90,000 lbs. This much greater than the AASHTO H20 heavy duty loading. CLICK for more detailed technical information on the properties of ductile iron.
Applications
- Class D400 Rexus II was designed to be lighter and resistant to the most severe use conditions, including heavy traffic and heavy vehicles.
Improved Ergonomics
- Advanced ergonomics enables utility personnel to undertake visual inspections and routine maintenance of underground networks with minimal effort and in complete safety. Hinges reduce the physical effort to open 60 lb cover by 50%.
- Hinges allow operator to move in a straight line, thereby avoiding damaging spinal rotation.
- Hinges minimize the duration of the lift; the hinge also retains the cover in a safe and controlled way during and after the lift.
- Lifting points in the cover are designed for use with standard tools (pickaxe/hook/bar).
Friendly Handling
- Hinge incorporates a 90º blocking feature to prevent accidental closure.
- Self-centering design of the seating gasket eliminates the need to guide the cover into position when closing
- Design of apertures ensures easy insertion and removal of tools.
- Lifting loops in the frame facilitate safe offloading and installation with the proper equipment.
- The cover can be removed if necessary.
