Evening all,
Any opinions from owner/opps or anybody that has spent plenty of time on the Volvo, Kobelco zero tail machines, 2018 onwards and needs to handle a Engcon as well.

Thanks

A friend just bought zero kobelco a couple of months ago and was/is very happy with it, and just bought another one off the back it, good performance and very good on fuel.

All three will be great machines, the Hitachi Is good but much more balanced with the blade

Don't complain - suggest what's better
I regularly hire a Komatsu 138us. Not a true zero tail, but very close. Very nice machine to operate. Smooth controls and plenty of power. Has the option of a blade, which I like. With the extra slice on the counter weight should handle an Engcon well. We run a sieve weighing 1500kg empty with no issues on a long dipper.

Stay away from a long dipper🤔, been on plenty standard machines...long dipper...tilty, cross carriage and back end lifts up, reduced/zero won’t be any different, you want to be on top of the job not on the boarder line.

We used to say that if you have the option go for a slightly shorter dipper to compensate for the build height of the tilty (say 500mm), but over the years talking to the OEMs a number of them tend to prefer the 'sausage machine' approach - i.e. keep it as standard as possible. I'd certainly agree with Ollie on avoiding a long dipper (especially with the prevalence of RTS or ZTS machines these days). That having been said, we've had an order this week for the environment agency for a CX210D long reach, but is was a smaller EC214 (14tonne) tilty. Depending on the application and breakout force, you can put smaller tilties on LR machines.

You have the option Robert when/if buying new, as to what length of dipper you want. Pacific machines, i.e your LR machines have the extra weight put in, with options to add extra slices of weight, it’s harder to do that on just the standard site machine.

Used to own a Doosan 140lcr with a long stick, Engcon with top hitch and it handled this ok, at full reach with the grader on inc some material it was at its limit so long as you used some common sense it was ok.
I can see the benefits of a short stick but this would be a pain if you were using it in a standard set up and my be harder to move on?

Agreed. 5 years ago it was more common to sell an Engcon-equipped digger without the tilty because the demand for them wasn't there. Opting for a shorter dipper would have had an adverse effect on the resale of the bare digger. Nowadays, there is a stronger demand for well set up diggers with tilties so the need to take it off has disappeared (especially with the current exchange rate against the Scandi countries)

they're a nice machine .... got some time in one o' them with Alex a while back - self loading if he was busy and leveling out our tip area ... was some tool ... but pushing 18t, with a blade, was pretty planted most of the time .... would have one in a heartbeat (y)

The Doosan was a well planted machine but the hydraulic feel was not the best, coupled with poor back up from the dealer and Doosan, got shot of it in the end as I was feed up with waiting for the issues to be resolved

Tracking, if you used the tracks and the boom and stick together more so when slowing to a stop you'd get a jerky motion to the point where I had to stop and start again, after 12 months of waiting they changed the pilot pressures which slightly improved the tracking but made it hard to grade with a speed, it bobbed up and down.
They were going to do a deal on a dash 5 but I got feed up with waiting and excuses from the dealer blaming Doosan.
The feel from the boom was not the best, if you wanted to pick yourself up and turn on the heels of the tracks it felt as if the boom had to pressurize before moving resulting in a sudden movement.

I Sometimes get into a Bobbing motion with the sticks that won't stop until I let go of them and everything comes to a stop and I start again. I just out it down to my inability to drive an excavator smoothly :oops:

You just adopt a different driving style that’s all, just don’t move back as far, as for moving it on, you’ve got the whole of Europe to sell into, not just the UK.

I've driven machines for the past 23 years, 8/9 of those were on case ,Jcb, cat 180's, all on sticks, you can operate around the machines niggles but when they are doing things that you cannot control it becomes beyond annoying and makes you look as if you don't know how to operate.
