Re: tank car question

In the pressure vessel business, that thing that supports the manway
flange would be called a 'davit'. Typically it's specified for any
flanges that are too heavy for one man to handle, which often means
100 lb or more.

Manway flanges were once as small as 16" or 18" nominal size, now are
normally 24", but workers are bigger now.

Tim,

That is an ALCO switcher...oh... you mean that round thingy...
looks
like a bolted flange for a clean out hatch. Note that it has a
support
structure for when it is in the open position. Not sure what would
be
the load or why such a clean out procedure would be required.
Very
interesting none the less.
