Doosan excavator problems

Private Seller? Create your ad. A contractor who specialises in setting up petrol stations reckons the Doosan DXLC excavator was seemingly made for the job.

Operators spend up to 14 hours a day in their machines, so comfort is critical. But once the comfort box is ticked, the driver still has to have confidence that the machine will deliver the grunt required to do the work.

Fuel Installations FIin operation since the s [in New Zealand], provides all the products and services needed to set up a petrol station and keep it running smoothly. That includes everything from complete turnkey service station construction to maintenance and upgrading of existing facilities. The company has built 10 new sites and upgraded more than more in the past three decades. At its heart is a new common-rail Doosan DL06 engine, with four valves per cylinder. The engine, combined with the new e-EPOS electronic control system optimise combustion, results in grunty power, increased fuel efficiency and minimised pollution through reduced Nox and particulate emissions.

Its principal work is sheet piling.

It's set up for a compaction equipment breaker, a demolition crusher and a Movax sheet piler. CEO for FI, Bryce Bacon, says Movax in Finland specifically recommended the DXLC due to the flow rate and power needed to drive the Movax vibo units: "With the space next to the cabin, the Doosan could accept the addition of a powerful hydraulic pack to boost the performance of the vibrating hammer. The competitively priced unit allowed for funds to allocate towards extra safety equipment on the machine.

The additional safety equipment includes a front grille operator protector and reversing cameras. The operator readily explains his affinity for Doosan and especially his preference for the DXLC: "I remember as a younger man working on machines with up to six hand levers and two sets of levers operated by foot. Every time you moved one, it would whack you in the knee.

At the end of the day you would be so tired, you would not just be holding the levers, but choking them. We spend up to 14 hours per day in these machines. That's why driver comfort is so important. The operator mostly builds steel boxes for fuel tanks. One hole for one tank is about 12m long, 4. It takes about three weeks to construct the hole and install the tank. An important aspect of operator comfort is visibility. Today machines are much better designed, but there are still a lot of things crammed into a tight space, which makes visibility one of our biggest problems with diggers.

In any event it's difficult to see people over two-and-a-half-metres of digger. Today, most diggers have a reversing camera as an optional extra, but in an ideal world I would like to see it as standard.

There's enough stress in just getting the job done. It would be great not to worry about what's going on behind your back, too," he says. The operator says the DXLC has a wider-vision cab than any other digger he has operated: "You have to see it to believe it. I think the DXLC gives the best operator access and comfort around today - I can get in and out without problems and stand the time I spend in it easily.

The DXLC is also his favourite because its sheer power cuts digging time by about eight hours per hole: "That's a big deal for us. I gave the Doosan dealer some feedback about small changes I would like to make, such as stronger track motors, but all things considered this machine is superb.

The Caltex site on which the machinery operates is on a major thoroughfare in a busy suburban area, and the FI team shares it with a team from another construction company building a fast food outlet.

Space is at a premium: "The DX60R is a good little digger, especially around a workplace like this.The CX minimum-swing-radius excavator is able to work in confined spaces, such as a single lane of traffic. Case says the selectable cushion control on the boom and arm functions increase material retention while reducing shock loads.

Product-line features: Auto work mode simplifies machine operation by automatically matching the boom, stick and swing priority to the task at hand. A power-offset boom is available for the C CR minimum-swing-radius modelgiving it the ability to dig parallel with the edge of the tracks. Unlike the articulating boom, or swinging boom, which hinges at the base of the boom only, Cat's power offset boom is a custom option with two hinge points built into the boom.

The 32,pound unit is one of the largest excavators with the capacity to excavate the entire width of the machine with walls parallel to its tracks.

Cat's electronic-control system automatically selects boom and swing priority and delivers full engine power as needed. Product-line features: Cat's Pin Grabber Plus hydraulic quick coupler for attachments is available from the factory throughout the to ton range, as are medium pressure circuits. These circuits increase machine compatibility with powered work tools that include tilting or rotating mechanisms.

The system coordinates engine and hydraulic efforts to match the horsepower, hydraulic flow and operating pressure to the demands of each job. Upgraded electronics also simplify selection of work modes.

Product-line features: A hydraulic diagnostic system can be accessed via laptop to display work history as well as real-time performance data in graphed or numeric format. The system stores fault-code history in memory for later analysis. Gehl changed the power source in its 25,pound from a Yanmar Tier 1-certified diesel to John Deere's TF Tier 2 turbocharged engine. To find an excavator with more than the 's 99 horsepower, you have to start looking at machines that weigh almost 2, pounds more.

Product-line features: The combines compact-excavator features such as a standard dozer blade, auxiliary hydraulics, and independent boom swing with the power of larger excavators. The Zaxis excavators were introduced in with improvements measured in cycle times and digging force even with increased fuel economy.

Hitachi says its Auto-Accel power mode, which varies engine speed to match hydraulic-system pressure can cut fuel use by 10 percent in light-load applications. The greasing interval in boom and stick joints increased to hours with special bushings and thrust plates.

Engines go hours between oil changes, and the hydraulic-oil-change interval is stretched to 4, hours. When Hyundai introduced the Robex Dash-7 excavators to replace the Dash-3 machines with Tier 2 compliance, they also carried a hydraulic upgrade. Mode selections offer the operator a choice of hydraulic speed and power settings.Private Seller? Create your ad. The team liked its near zero radius tail swing, which makes it ideal for Tracks' work in often confined spaces.

The dozer blade impressed the operators with the extra capacity it delivers. In addition, considering the value for money the Tracks' fodder includes demolition; earthworks; site preparation and levelling; drainage; concrete works and paving; precast panel supply and erection; the building of retaining walls and other varied timber works; road construction; and large civil construction works for private developers and local councils.

Recent repair work in the area required an agile, stable machine that could manoeuvre easily in tight spaces on difficult terrain, yet deliver the necessary power to dig, pull, and haul sizable loads. Young says the Doosan handled these jobs well, "but it can also be used for general work such as site development, which makes it overall a good buy". The machine's ultimate competitive advantage for work in confined spaces in both built up and rural areas is the capability it delivers for its size," Doosan general manager Theo Valk says.

Valk says the compact DX LCR, with an operating weight of 15,kg when fitted with standard boom, arm and 0. The operator has plenty of room and great visibility - even a sunroof - and all the essential controls at his fingertips. The "best in class" four-cylinder Cummins QSB4. This means the electronic power optimising system can generate major power from little force.

It connects to the engine's electronic control with a data transfer link, which further harmonises the engine- hydraulics operation. A major standard safety feature is the hydraulic safety lock set-up, designed to stop bucket and boom falling on someone's head. The machine has a built-in user friendly auto idle feature that, Valt says, reduces noise and further saves fuel.

Valk says "the workgroup is also much stronger". The shape of the boom has been optimised, allowing uniform load distribution throughout the structure. The arm assembly now uses cast elements and has extra reinforcements around the bosses.

These capabilities bring dependable stability, especially on treacherous ground. Valk says the machine's outstanding performance in this respect, even when fitted with long front-end equipment, is the result of three factors. Firstly, the grunty 3.

Secondly, a newly designed and strengthened chassis frame section provides a strong undercarriage anchor between the workgroup and house and the tracks. Finally, the 3. Engine service intervals have been pushed out to hour intervals. This is due to Doosan's use of new polymer shims, and the new design of the bushings used at the boom, arm, and bucket locations. In addition, easy access panels simplify servicing and maintenance of engine parts and spares.

Operator Tony Lumsden, who has been putting in long hours on the Doosan, has only positive feedback about the machine. He is particularly pleased with the cabin's comfort and space, the sound absorption features, and degrees visibility, the result of a pillar-free window, rear mounted camera that displays on a colour monitor, and right and left rear view mirrors.

The blade is also a winner: "It took me about two days to get used to the new machine, but it is so well designed and comfortable, eventually I didn't want to get out until lunchtime or knock off time!

The visibility is the best I've come across. The bottom window on the right-hand side is valuable to see where I've been and what I'm doing with the blade. The camera took some getting used to, too, but I'm using it all the time now to estimate my position and reverse in tight spots.Log in or Sign up. Heavy Equipment Forums.

When the Doosan engines came out in the bobcats, think it was latethere was talk about them having issues in the winter months where they would lose power and people where having problems with them not wanting to run correctly.

Im wondering now that the doosan engine has been out for a while if they got the problem worked out with this issue or if its still a issue?

Thanks for joining us and I hope you enjoy your stay!! Welcome to HeavyEquipmentForums. I hear that they are pretty good but I want to get more opinions on them. A guy I know recently bought one and really likes it.

From what I hear they are a great machine. I do believe getting parts is a pain in the neck. I think no matter what your better to spend the money on a Deere or Komatsu. But all depends on how long you'll use it for, what you do with and of course personal preference.

He runs a pit, crusher, does road work,etc. I have run there loaders, and excavator. They seem strong and smooth but are put together with lighter plastic in the cab.

Dwan HallJul 10, We just finished up a site where another contractor brought in a Doosan Our operator was laughing at it until he jumped in and tried it out for a bit. I have never seen him so shaky on a machine, he couldn't handle the speed of the orange beast. The Doosan machines are fast, quite reliable, easy on fuel and a nice machine to run. Yes the cab is cheap and somewhat crappy but the old Daewoo I ran was nice, the only excavator I have ever run with a tachometer. They will give you great service and dealer support in Canada is decent.

The only problem I know of thats serious has been solved for the most part. I talked to my old boss about his and apparently Daewoo had some issues with the mount where the boom joins the upperstructure. That mount is somewhat weak on some machines and the boom can actually tear off the upperstructure.IP: Doosan DX Problem.

Hi folks This is my first post on this forum, and I'm hoping that someone on here might be able to help point me in the right direction. I've had it for a little over 4 months and it hasn't been as reliable as I'd hoped with it being such a new machine but most of the problems have been small problems that have been easy enough to sort out. The latest problem looks like it might be a little more serious though, I've been getting oil in the coolant no coolant getting into oil for a few weeks now, and after changing the oil cooler over the weekend and giving the old cooler to a local engineering company for testing they came back to me saying that it tested fine.

The machines only been working for a day since the new cooler went in so too early to say if the new cooler with the new gaskets has sorted it, but I'm just wondering if the oil does reappear which I'm kind of expecting now that I've been told the old cooler was okis there anything else I should check out before diving in and changing the head gasket?

Waterfall Formwork. Re: Doosan DX Problem. Its a 6 cylinder doosan DL It starts and runs perfectly with no smoke, no overheating, no bubbling in the radiator, none of the typical head gasket signs, just oil sludge building up in the radiator every days after flushing - which is why I'm a bit hesitant to jump in and pull the head off. I would strongly sugest the engine oil cooler is at fault. To view links or images in signatures your post count must be 10 or greater.

The problem seems to have cleared, so I'm guessing there was a problem with one of the gaskets, as there is nothing wrong with the old oil cooler. I'm still getting slight traces of oil in the radiator but that should hopefully clear up with a couple more flushes.

That's great news, if you have any further problems give me a shout and I will get one of our dianostic engineers to talk it througH with you.
