Here at Manhole Covers Direct, we provide a variety of Manhole Covers and Manhole Cover Replacements. At times, you may wonder what load rating do I need for my application. How do I decide?
Manhole Covers Direct can design your cover to withstand any specific single-point wheel load up to 100,000 LBS. This includes loads from foot traffic only to light-duty, medium-duty, heavy-duty, and extra heavy-duty. What is the difference?
FOOT TRAFFIC rated covers are suitable for locations where there is no possibility of vehicle contact. Foot Traffic rated covers are designed for foot traffic only.
LIGHT DUTY rated covers are suitable for locations requiring single-point wheel loads under 1,000 LBS. Our Light Duty covers are appropriate for areas such as sidewalks or locations that only see lightweight vehicular traffic, such as golf carts or lawnmowers.
MEDIUM DUTY covers are H-20 traffic rated, allowing for a 16,000 LB single-point wheel load. Our Medium Duty covers are appropriate for low-volume general traffic applications under 25 MPH, such as gas stations and residential parking lots.
HEAVY DUTY covers are H-20 traffic rated and are designed to withstand a single-point wheel load of 16,000 LBS. Our H-20 traffic-rated Heavy Duty covers are designed with extra support for general traffic volume under 25 MPH and are appropriate for areas such as commercial parking lot entrances or loading docks.
EXTRA HEAVY DUTY rated covers are custom designed to withstand single-point wheel loads greater than 16,000 LBS based on your specific request. Extra Heavy Duty covers may be considered for applications where concentrated loads might be applied, such as when heavy machinery and equipment are present. Heavy Duty Covers may also be installed at seaports, transfer stations, small aircraft hangars, or any location requiring a single-point wheel load of up to 100,000 LBS.
Our manhole covers are not designed for city streets or highways. Due to the high traffic volume and speed, street manholes should be cast or ductile iron. Do you have questions?
