Bucyrus Erie crane truck

[Mikem]

Hi Shawn what are planning on using for a swivel on the crane house

[Krewmember]

The plan is to get the swing mechanism as close to the real machine as I can. So I'm going to machine a custom swing ring and cut internal gear teeth in to it just like the deal.

Here is a diagram of what I have been able design based on what information I have.




The ring will be mounted to a base by bolt holes tapped in the ring, the base will have the bearings for a central shaft that will be mounted to the crane frame. The frame will have rollers that go inside the race in the ring, like this.

This is interesting the ring mounts to the truck then the wheels are mounted to the crane and support the weight of the crane ? Is there a center pivot ?

[Krewmember]

Yes, there is central shaft that runs through the crane base to the ring base
