Posted on April 6, 2022 by admin

BIC in partnership with Confederation of Indian Industries (CII) and Young Indians (Yi) Kolkata chapter conducted an eye screening camp for all staff and workers at our Howrah plant. As a manufacturer of ductile iron manhole covers and other castings, we wanted to help in little ways possible to improve the lives of our employees.

A total of 150 people were screened and tested by experienced personnel from Carenetram. After eye screening the workers were provided with subsidised glasses at Rs. 100 only. They were also given the opportunity to get a cataract removal surgery done in the near future free of cost.

In addition to this, blood sugar and blood pressure testing was also conducted. Lifestyle management solutions were provided to all workers to maintain a healthy blood sugar level.

We are thankful to Yi Kolkata Chapter for providing us with this opportunity to impact and care for the lives of our employees who work so hard to manufacture world class cast iron and ductile iron manhole covers, hubless pipes & fittings, and other industrial castings.

Manhole Cover Load Guide

This article serves as an easy guide to selecting the right manhole covers based on load class for your design requirements. We have compiled this data using the codes IS 1726 for grey cast iron and EN 124-2 for ductile iron manhole covers and grates.

Grey Cast Iron Manhole Covers and Frames Guide

In India, the Grey Cast Iron Manhole Covers and Frame have been divided into 4 categories based on their usage as per IS 1726.

LD-2.5: The Light Duty cover is capable of withstanding 2.5MT or 25kN of load. These are suitable for use within residential or institutional complexes or areas with pedestrians as well as only occasional Light Motor Vehicle Traffic. These covers also used as ‘Inspection Covers’.
MD-10: The Medium Duty cover is capable of withstanding 10MT or 100kN of load. They are suitable for use in service lanes, on pavements for use under medium-duty vehicular traffic including car parking areas.
HD-20: The Heavy Duty cover is capable of withstanding 20MT or 200kN of load. They are suitable for use in institutional and commercial areas, carriageways, city trunk roads, bus terminals, with heavy-duty vehicular traffic of wheel loads between 5 to 10 tonnes, like buses, trucks and parking areas and where the manhole chambers are located in-between the pavement and the middle of the road.
EHD-35: The Extra Heavy Duty cover is capable of withstanding 35MT or 350kN of load. They are suitable for use on carriageways in commercial, industrial and port areas, near warehouses or godowns where frequent loading and unloading of trucks are trailers are common, with slow to fast moving vehicular traffic of the types having wheel loads up to 11.5 tonnes irrespective of the location of the manhole chambers.

C 250: Capable of withstanding 250kN or 25 MT of load. The area of kerbside channels of roads which, when measured from the kerb edge, extends a maximum of 0.5 m into the carriageway and a maximum of 0.2 m into the pedestrian area.
D 400: Capable of withstanding 400kN or 40 MT of load. The carriageways of roads (including pedestrian streets), hard shoulders and parking areas, for all types of road vehicles.
E 600: Capable of withstanding 600kN or 60 MT of load. Areas imposing high wheel loads, e.g. docks, aircraft pavements.
F 900: Capable of withstanding 900kN or 90 MT of load. Suitable for areas imposing particularly high wheel loads, e.g. aircraft pavements.
