Re: Hi-Tech airbrake hose installations


U-Bolts were used where the pipe runs directly along side a surface. A Pipe Clamp and "Standoff" is used where support is not adjacent to the pipe. Pipe Clamps and Standoffs are a welded assembly with formed straps (sized for the outside diameter of the pipe) where the pipe fits and a bolt at each side of that strap clamps the pipe in place.

Utah Pacific GE lift rings are small. Another use would be fine soft brass wire and just wrap through one hole capturing the pipe...

I have peeked under the skirts of many boxcars and air line pipes were frequently mounted with what looks like a muffler clamp (a U-bolt), and the GE lift rings come awfully close to that look and function.

I'm not sure what lift ring product you have in mind
Andy. Would it have
the appearance of the prototype? If not, why use such a
part with a fine
scale detail part?

Looking closely at the new Hi-Tech air brake hose, I
don't see a need for
the PSC airhose bracket.

The Hi-Tech part has a length of train air line of
about 26 inches molded
as part of the hose, and this hose has a mounting
bracket cast as part of
the hose with an angle cock shut off valve molded on
as well. If someone
were to use a small brass lift ring the air line could
be attached to the
side of the coupler draft gear box for a simple and
very secure
attachment. There would be no need to use the
(redundant)PSC bracket.
Other mounting locations, like to a small plate
suspended from the end
sill, could still be provided by using the same small
lift rings as a
mounting clamp. Glue might even be unnecessary.

It sure is nice to have these fine scale features in a
