Larger disc chippers

[arc]

Does anyone have any experience of the larger disc chippers, especially the TP 270,280 or 400k models.

I'm thinking of a reverse drive tractor with 3pl mounted crane fed chipper, it would need to blow over the tractor cab and into a trailer or other vehicles and have direct in feed, i.e. not at a right angle for working in confined spaces.

 

Any thoughts would be welcome,

Crane feeding disc chippers can spell trouble

[Mr Ed]

Very true. When you crane feed a disk, you effectively override the roller infeed, forcing material against the disk, putting severe axial load on the bearings and in the worst scenario, forcing it back against the housing.

The other problem is infeed size. The bigger you go, you need to increase the size of the disk dramatically.

 

Disk chippers are essentially outdated technology. A drum chipper gives you far more rotational torque, greater infeed / cutting mechanism size ratio, better knife wear, heavier bearing support and overall compactness.

 

Trouble is, a good 3pl drum chipper is hard to find. What size tractor do you want to run it on?

 

I can give you a lot more detail if you PM me.

I know mate, I'm not wanting it for fuel chip production so it wont be sat at the side of a load of brash having all sorts put through it via an in-feed conveyor, its mainly for large dismantling and smaller scale site clearances to reduce workload on staff.

I think the drum chippers are a bit clumsy for this but if I could get a smaller heizo, direct feed and extended discharge I would prefer it.

 

I think I need to speak to Alex again for about the 30th time about this.

IF you want a heizohack....

True, are you gonna recommend a Yankee one???

I've seen a few different makes in magazines and stuff and would look at any make if it was the right machine.

I have spoke to Alex on numerous occasions about mounting a HM 8 400 on a 5 tonne excavator chassis or marroka dumper with crane and donkey engine, but I always go away and think about it and think theres probably a better idea somewhere.

Sometimes I just wish I could stop thinking about stuff like this, It stops me getting to sleep.

been there done that arc, in your head the valmet crane chipper combo is amazing, but the reality is a ball buster, you will need 100k easy even before you get a good trailer made up. the roofmount i had was amazing, it was designed for hte job you want, but i didnt want a hiezo because of the feed angle, the crap you put through a chipper with a crane is the killer, a drum can take it, but hte disc ones dont like it. getting to jobs are slow as hell. i have just picked up a bandit 250 tow behind, and the chipping power is amazing. i think you are the guy with the massive rig anyway. i would shuttle the brash to the chipper on a site. the one machine, one worker is ok until you get a break down, and with all those hoses you will get them. there is no room in the tractor to carry tools or saws, and if you need to nip away to get stuff you cant, unless you have an astra van in the trailer aswell,

Of course. Not that the hiezohack is a bad machine in any way, and if you ask Matt he is Alex THE man to get one in the UK from. But I can supply a simpler machine that chips better with a decent sized rotor, only 4 knives, direct discharge, and will fit on a 3 PL or have anything up to a 500hp CAT factory fitted.

Horses for courses, I just like to offer a different option.
