Valve required for a Plasser Crane

Can anyone shed any light on this?

Plasser Cranes and TRM's have a pneumatic double check valve in the braking system to the brake cylinders.

It is listed as part number PC 15917 in the Plasser parts book.

It appears even Plasser do not know this number now, We are sure it is either a Knorr Bremse or Westinghouse part. used also on Loco's

Trying to find this part for NYMR crane.

I appreciate Tampers etc have a similar valve in the braking system that would suffice with a part number that can be sourced, but would like to track down the correct one.

Any Ideas please?

 

There is a separate Westinghouse parts book for the cranes and TRM's brake systems.

The Plasser number listed may be the reference to the page or listing in this parts book.

You will need to find someone with a copy of this additional book as this will have all the brake part numbers.

 

Been out the Railway industry for a good few years but when I was PTO at Three Bridges OTM depot in the nineties I had a clear out of the stores at Woking & Eastleigh and slung piles of obsolete spares away from machines that were long scrapped. Likewise there was also a lot of tech manuals that went as well. Now that the 07s, GPCs, TRMs are more or less history it may be worthwhile contacting Balfour Beatty at Hither Green and finding out whether they are going to dispose of the no doubt massive amount of spares that have been on the racks for the last two decades. You may get a bargain and a load of tech docs from the library

 

Thanks for the replies on this.
We will be asking around even more than we have before.
