I have a Bucyrus Erie 15b dragline and everything works fine but I can not get the boom winch to operate to raise and lower the boom. Can anyone explain how the boom mechanism works. I have freed up the lever that operates the brake and clutch, and I see that there is a "parking paul" inside the drum to hold the boom in postion. Any help would be great. It has been 30 years since the boom was moved.

My Dad worked for the local BE dealership back in the 70's and early 80's, so I've been into many of the BE's working with him, from the 22's to the 25B's,and on up to the 71B's, with a lot of 30B's in between....... Unfortunately I have not been into a 15B specifically. Most of them are similar in operation, but not always. I'll dig out one of my books later this evening and see what's going on and post back.
I don't check messages every day, but my email is open if you want to get up with me that way. I'll also be happy to give you my number in case you have other issues. Wayne

Hey again. I didn't get a chance to dig out the book today, but I did talk to Dad, who verified what I was thinking was wrong.
More than likely, if it has sat that long, the brake band is stuck to the drum. The brake lining has metal fibers in it, and the lining will rust to the drum over time. The result is the brake won't release to allow the boom to lower.
The remedy is to first insure the boom is supported by the locking dog. From there, back the brake band off as much as possible. Then take a hammer and "gently" tap around the length of the band. DO NOT smack it too hard, or concentrate the hammering in one area as you can damage the band. Once you see the band is free from the drum, tighten it back down until you've got just a touch of free play, and see what happens from there.
I'll try to get to the book tomorrow just to see if I can see anything else to go wrong, as with anything that has sat, unused, for that long, there may be more problems, but the majority of time a stuck brake band is going to be the main problem.

The brake band was stuck to the drum and got that freed up. The clutch pads on the inside of the drum seem to be not grabbing very well and they seem to be worn down pretty good. Short of replacing them I was thinking of putting something in between the clutch pad and the drum and see if we could get some more friction. Not really what I want to do but don't have any other ideas except trying to get the old shoes off and having them relined. I am assuming that the sprocket and chain on the unit is to control the boom lowering. The cog inside the gear is worn down and broken so I am making a new part.

When I had my 15 -Bs , 22 -B and 450 Shield Bantam , I always put Comet or Ajax Cleaner on the brake bands , cleans and makes the friction better on the bands . What engine is in your 15-B , Cat or GM ..?
Glad to hear you got things somewhat working. I'll go with Dozerbill on the Ajax, Comet, or Bon-Ami powders to help get the frictions back in shape and biting a little better. If you've got any oil on them, Fullers Earth sprinkled in will help get it off. There is a new product out there called Star Dust that will do the same. I haven't bought any of either, so I don't know what it would cost, or anything. I just know for a fact the Fullers will work, and I've seen the other stuff used in a different application, and saw how it cleans and sucks up oil, so I imagine it will be as good, or better.
If you run into any more problems, like I said, feel free to get up with me. If I don't know the answer, I either know someone that will, or have the resources to find out.

Dozerbill this has the Buda Diesel motor. Seems to start and run pretty well. The Ajax/comet sound like a great tool for my problem, and I will be taking that with me tomorrow when I go to work on it. The guys I'm buying this from adjusted up the clutch/brake linkage today and for the first time in 30 years the drum for boom stared to turn. Another friend was able to weld up the parts the control the decent of the boom, so hopefully tomorrow is the day we get the boom lowered so I can get her home. Thanks for the ideas.
Thanks for the help and suggestions folks. I used the Comet and that did seem to get the clutches grabbing better, and we were able to get the boom down. Got it loaded up and moved home today and boom is operating great now. Still have a lot of TLC to help her out after sitting so long but nothing major. Thanks for the help again. Couple photos to show off the old girl.
