DynaGuard Products : Unmatched Performance and Durability

Size Selection

Load Bearing Capacity Selection

Load 2.5T (LD)
(Point Load/ Wheel Load 0.8T)

Areas where can be used by footways, pedestrians areas, side walking ways, or pedal cyclists.

Load 5.0T (LD)
(Point Load/ Wheel Load 2.5T)

Suitable for use in areas with light Motor vehicle traffic underground parking decks in residential areas.

Load 10.0T (MD)
(Point Load/ Wheel Load 3.0T)

Areas where can be used by footways, car parks, driveways etc.

Load 20.0T (MD)
(Point Load/ Wheel Load 5.0T)

Roads for relatively slow moving traffic, i.e minor residential,   r   e   s   i   d   e   n   t   i   a   l  , cul-de-sacs and frequent traffic area.

Load 40.0T (MD)
(Point Load/ Wheel Load 11.5T)

Areas such as power stations, carriageways, hard shoulders, parking areas for all vehicle types. For high density traffic conditions we recommend the use of vibration resistant locking system.

Load 60.0T (MD)
(Point Load/ Wheel Load 20T)

Areas submitted to high wheel loads such as ports and dikes or dock laterals.

Load 90.0T (MD)
(Point Load/ Wheel Load 30T)

Areas subject to particularly high wheel loads such as runways

DynaGuard Installation and Maintenance

Please note frame is not load bearing and therefore has to be completely supported from all sides. For more specification follow instruction of installation.
Service-life

Dudhi DynaGuard FRP manhole covers have long durability Upto 50 Years

Storage & Handling

Transportation: Lay in flat of manhole cover with a pair of Frame and cover plate during transportation.

Handling: Bigger size of manhole cover is heavier in weight so engage two persons at least to carry in loading or unloading. To avoid damage of corners and edges, keep the cover plate in safe place during fixing of frame.

Background Preparation

The foundation of the chamber should be casting the concrete M-30 or even better, the frame around the concrete width should be around 200 mm.

For More Specification Follow Instruction of Dos or Don’ts

Application

Make sure that top level of the frame should match the road.

Prepare concrete bed considering height of the frame

Frame should be allowed to set in concrete for a minimum time of 48 hrs, before its use.
