Something with about 2 metres more boom length.Before I go and have a look at one anybody running one or know what to look out for?
I’m on my 3rd, as we change every 4/5 yrs so we don’t have issues. They have been trouble free for the most part, and built heavy so they take the little knocks well. Our last matbro was fit for scrapping when it left at 4 (might be exaggerating, but only slightly) whereas the last Schaffer was still tidy at 4. We changed as we had a bit of money to spare and were pleasantly surprised with how it had held its value. Only things I can remember are a new hydraulic pump which I changed myself and a part for the oil cooling radiator which took a few days to source, and I think that they were both on the first machine, and a few oil pipes obviously, but that’s wear and tear really.
Ours is on the widest possible tracking, have had pivot steering machines since 1984, the Shaffer is definitely not as stable as the Terex it replaced, but is 100% more reliable, 25kph and 30kph down hill, think they have improved road speed since we had ours
I tried one a few months ago but ended up buying a weidemann , the main difference being the weidemann has a proper locking diff , where as most others have a limited slip diff which makes the steering heavy and scrubs tyres off , where as the weidemann is effortless to drive and with 3700hrs the tyres are barely worn where as limited slip diff models tends to be completely bald at 3500hrs . Weidemann also has better legroom , the scaffer has a low dash that you bang your knees on . Build quality bob on with either model though
JCB 320's have limited slip .What do you put that down to? Narrower, or more weight, or higher centre or gravity?
Interesting points about tyres. Our last machine was a Weidemann 3070 with manual diff lock, and we took over four thousand hours out of the first set, replaced them, and then sold it not long after. But that was running them bald for probably a thousand hours. Can't be sure. I'm guessing the canvas was showing when we replaced them. ?
That was our first pivot steer. Previous models were all Kramer four wheel steer with limited slip. They were definitely harder on tyres - bald at 2k hours. But then also they came on really crappy continentals. BKTs in that size have been twice the tyre at two thirds the price. I also thin that four wheel steer LS is generally harder than our current pivot steer on LS. You don't hear near the same scrubbing as with the four wheel steer. Current tyres are BKT, about half way or a little more at 1800 hours, so not too bad. Project baldness at about 3k. It does have a ton and a half more weight than the Weidemann on exactly the same wheels.
What diffs do JCB 320's have? Our neighbour balds them in 2k hours.
Yep. Got it two years ago with 50 hours on it, and it's past 1800 now. Model 8610.
Problems:
- Wiper motor wrung off the shaft at 1000 hours. Warranty. That's the only part she's had bar filters.
- The boom suspension isn't just as good as our previous shovels from the Kramer/Weidemann family. Been looked at by dealer, and a touring mechanic from the factory, without any improvement.
That's it so far, as you be hoping for.
100hp deutz engine, hopefully 40,000 hours in that. Axles and hydraulic pump brands are German as far as I know. Mine was the very last of the old model. The 8620 had already been out 6 months, so mine thankfully is pre ad blue. Pins and bushes are heavy. The ones in the scissor in the head are huge. We like it a lot. The only thing I can't report on yet is that the pivot is a sealed unit. I like to be able to grease things like that. But obviously they decided at the factory I wasn't going to...
Which model are you looking at? A whole lot depends on the previous owner, and how it was maintained. A lot of folks don't use enough grease. Put the head on and off the ground and watch the pivot to see if there's any slackness there.
What do you put that down to? Narrower, or more weight, or higher centre or gravity?
