We have patterns for several models of the original Birdsboro-Buchanan jaw crushers and some even with slab-tooth design jaw dies here at Columbia Steel. If basic pattern equipment exists for a given model of the Birdsboro crusher, we can get to a "slab buster" jaw design fairly easy. If the basic pattern equipment doesn't exist, then the cost of the project is amplified considerably.

In order to identify what parts you need, it's important that the size and model type are identified properly. It's even better to find the actual part numbers on the castings needed. Old Birdsboro went about doing things more than one way. For example, they'd call out a crusher as 60x84 type "C". There can be another version of a similar sized crusher known as a 60x84 type "C-DF" -- and it would use altogether different parts than the other one.

The people that are really in the know on these crushers, and who may make some of the other items you're looking for, are known as P.R. Engineering in Oshawa, Ontario. They may be able to help you with the spacer wedge and toggles. There's another outfit up there in Kitchener, Ontario, known as Automatic Welding Machine and Supply Company that specializes in hydraulic toggles for many different models of jaw crushers. They make some pretty nice gear. Let our Columbia Customer Service Department know if we can help you with the "slab busters".
