Small Crane Fed?

[Brushcutter]

I wouldnt try to crane feed any disc chipper fwiw.

 

Why not?

Because any material forced through the feed rollers will exert a twisting force on the main bearings, ok if your crane operator is gentle, but not worth the risk imo. Also smaller disc chippers tend to have easily broken switches and stop bars, which are expensive to replace.

 

When you force material into a drum chipper, all the happens is it gets shoved under the drum, and since the drum has a bearing at both ends it is a much stronger design.

 

Just a case of getting the right tool for the job really.

tractor is ferrari vega rs 85 Lamberhurst Engineering . with seppie fixed tooth flail will do a surprising amount of work ! I don’t know if the 250 has bigger bearings set up for crane but this chipper was bought off of the Osbourns stand at the Lockerby APF and we have had no problems with it but we have suffered flywheel into anvil on hand fed disc chipper with end float on shaft, am happier stuffing trunks into the hiezohack but have pushed the limits of the TP thankfully without and disaster so far , Ferrari has surprising ability ! off road not found its limits yet!

I see. I dont force the stuff through i just use the crane to get the material to the rollers and then let the rollers grab the stuff and pull it through with the grapple loose. I only crane feed sawmill slab wood offcuts anyway.
