Steel/Aluminum Access-Hatch for Direct Traffic Application (H-20)

Steel/Aluminum Access-Hatch for Direct Traffic Application (H-20)

Steel/Aluminum Access-Hatch for Direct Traffic Application (H-20)

(OP)
Due to space limitation, we were forced to put a sewer wet-well in the middle of a residential street (light residential traffic with max speed limit 30 Mph).  Can anyone recommend a steel/aluminum access hatch (w/ clear opening around 30"X36") that I can use for this type of situation?  Most of the access hatches that I've seen have an H-20 rating but specifically listed to be used only for "off-street" location.

Try Googling Bilco Doors.

RE: Steel/Aluminum Access-Hatch for Direct Traffic Application (H-20)

DON'T DO IT!  Even the Bilco people will tell you that their H-20 rated hatches cannot take anything more than occasional loadings.  They will warp and get very noisy.
Use a cast iron hatch by Neenah (http://www.nfco.com/) or Alhambra (http://www.alhambrafoundry.com/).

We have the same situation in South Forida.  We use US Foundary more specifically a DT-AHD 36" X 48" steel hatch. It should weigh about 1400 lbs. anything lighter should be questioned.  Good Luck

RE: Steel/Aluminum Access-Hatch for Direct Traffic Application (H-20)

Don't use 'non-hinged' rectangular items for a wet-well cover. Use round. When someone drops that 1,000+ lb item on the pump. You will figure it out.

Good Point!  Note that a round lid can't drop in either.

RE: Steel/Aluminum Access-Hatch for Direct Traffic Application (H-20)

Sorry dicksewerrat, you said it and I didn't read it.

RE: Steel/Aluminum Access-Hatch for Direct Traffic Application (H-20)

And the round manhole covers are already designed for H-20 applications

westend392,

See also East Jordan Iron Works for comparison to Neenah and Alhambra products (they all typically produce identical pieces).
