Been this way since new (2012 model with 2.5 hours at present) Twist forward motion grips, jack moves, twist more, jack continues to move at aprox the same speed, keep twisting and suddenly it picks up speed..a lot...like double the speed.....no smooth transition.
Reverse is better, but even there the speeds change in small steps rather than a seamless transition.
Dealer has made computer adjustments on two different occassions. The pot transitions look ok on the computer. They are tapped out on fix possibilities. Latest talk is that is "just the way it is" for that model.
(Curtis controller, if that means anything)
Do you guys agree the pallet jack is defective ?
Showing items 1 - 20 of 42 results.
glad to hear you finally got some positive results from this
good job rousting the naysayers into doing their jobs like they should have done in the beginning.
The dealer should have pushed this from the beginning when they couldn't figure it out instead of tossing it aside as an unsolvable mystery.
shame on them
Used the ECR to move full load (6K lbs) on Thursday and it performed very nicely. Wonderful to finally have a smooth and controllable ECR 327.
Strange that my post of Wednesday doesn't show as the last post. (on edit) Ah, now it does....
The ECR was delivered today. Trailered by the head dealer tech and the original dealer tech. Two techs from the MCFA factory flew in from TX to meet at my place as well. Initial run test by me reveals unit is much better but was still a little jumpy with initial speeds. Some adjustments on the computer and ECR better still and that I felt was good enough.
For those wondering what exactly was wrong with the pallet jack, their only explanation was the software. A problem they admit from the very first ECR's to come out of the factory in early 2012. They simply missed the sudden speed jump issue, and I was the first to complain about it. In theory everyone but me is using these things at breakneck speed and simply doesn't care or doesn't notice the acceleration jump and choppy traction.
I suppose that is possible but suspect there are many dissatisfied with their ECR but don't know any better, so don't complain. Some probably complain but word never gets back to the insulated factory.
I still find it hard to believe they couldn't see this themselves if all the ECR's performed like mine, as it was abysmal to use...and dangerous.
Regardless, the techs were nice folk to meet in person and my ECR is ok now. Not perfect, not quite the seamless acceleration and joy to use the older version is...but controllable and safe at least.
Your story is such a shame of poor dealer knowledge or support. I'd strongly suggest you to change your servicing company. They are not willing to take any risk to help solve that problem that is critical if we look at the safety of it. Don't wait someone get crushed. If that unit has been bought new and act like that since then. It looks like there is transistor problem in current control. A new controller is not such an expensive test and these control can fail so even if they replace it and it shows that the problem was not that then they just have to keep it. They will have one to try some time or even to sell it when they will need. Unless you are dealing with a very small place that we call "jobbers" there is no way your problem can't be fixed. Been a tech myself and when a tech say that it is just the way it is then sometime it is to cover their lack of aptitude to understand or fix the problem. Can't fix it then tell the customer it is normal. Most of the time the customer will believe because he must trust the pros. Sorry that you have to loose such an incredible amount of time trying to get answer for your product that you surely has paid a good amount of money. Hope you will be satisfied soon.
(FWIW, I had the forum moderator change my forum display name)
Latest word is a software update from the factory to be installed today or Monday and the ECR delivered to me on Tuesday. They seem pretty confident I will like the change. I sure hope I do.
I can't help but wonder about the thousands of this model shipped worldwide with the original software. I have yet to make contact with another ECR 327 owner or have a chance to operate another current version of the ECR 327.
But did run across someone with a current model Mitsubishi electric forklift that acted similar to my pallet jack. Probably made in the same Houston factory. They also were dissatisfied with their truck and also got the same "well, that's just the way they are" from their dealer tech. If this new software works I'll let them know about it.
ya i need a good chuckle heheh :o)
so they did come and get it eh?
well if they know anything about what they are doing with this machine they should have it repaired and back to you within a week. Especially if they already have a working machine there, they can just use the parts off it and get yours back to you asap. Then deal with thier truck afterwards since it was just sitting there anyway.
I still think that was a large expense on thier part to bring a haul truck down there to bring it back to thier shop when they could of just sent someone down there with the parts.
I surely hope they are footing the bill for these hauling charges :o/
Big rollback truck came today to take the ECR to the dealers headquarters in NC. Driver asked what was wrong with it, I said here, try it. He "got it" instantly....I should have taken a video of him struggling with it.
Their theory was since they have a good ECR 327 on site they can compare functions and swap out parts as necessary. They could simply bring their ECR here...but then they are probably thinking about all the trucking costs to get it here.
OTOH they could go ahead and remove the throttle pot and Curtis controller from the new ECR there and bring that down in a Toyota Prius if they so choose (yes I know they don't drive Prius's but just making a point)
Heck, with my luck they'll probably get it there, take a month to get to it, and then I'll be fretting with them just to get it back !
If i was that company in raleigh instead of inconviencing you by hauling the truck all the way there i would prep a tech/engineer with all the proper tools and some 'known working' parts such as a tiller control AND even a new controller and bring that down to YOU. NOT take your machine. Whatever is wrong with that machine can be fixed onsite.
I would not agree with that, i would make THEM come to YOU DThomas. After all you have been through with this thats the least THEY can do.
I seriously doubt they are dishonest in that way. Dishonest in representing how the pallet jack should operate perhaps but not to the extent of stealing things.
Better make a discreet mark on that battery and photo it. For some reason you will probably get it back with a different battery.
I told them that, and they say they have no loaner.
Then I ask if I can at least keep the battery (I have an older BT 6K jack with 48" forks that works fine but has no battery) and they say, nope, need the battery !
And this is not a podunk little dealer, this is the corporate headquarters of a major CAT dealer network.
Amazing, isn't it ??
Tell them you have lots of work to do with a pallet jack. Ask them if they can bring a loaner when they come pick your's up.
Update- Things are finally starting to happen. I emailed Junheinrich in Germany a few days ago. Didn't really expect a response as the only address I could find was a general "info" type email address...plus my email was in English. But somehow my note got passed along to a person higher up in the organization who seems to be upset with the service over here in this case.
So the head service guy in Raleigh, NC emails about the same time with a note that he had been trying to call me for the past two days but got "phone not working" message. (I have had calls from all over the country in that time with no one else having such troubles, so my BS needle pegs the red zone on that one) They want to pick up the pallet jack and haul it all the way to Raleigh so they can test it with the one they have there and possibly swap parts around, then ship it back.
The remaining controversy is that the Raleigh service manager says even when the sudden acceleration problem is fixed, the acceleration will still be in five discrete small steps rather than one continuous flow. I tell this to the Jungheinrich guy and he replies that is nonsense, it should be as smooth as my older unit !
Seems like after all this PITA they would just give me a new one that works properly and be done with it. Now I'm going to be without that jack when I need it the most.... leased my 16,500 sq ft building and need to move all out this month...which involves much pallet jack usage.
Anyhoo....finally a contact on the other side of the Jungheinrich iron wall.
RCA, the chattering sounds are the two freewheeling side support casters....yet another unique irritation of this pallet jack. I've never heard a pallet jack's casters be so noisy as this one.
But then the noise results from the erratic speed of the jack so it's probably not defective castors or even their adjustment so much as it is just a result of the main problem.
Re the lawyer idea, one of those things that sounds good on paper but the reality is the dealer is nearly a two hour drive each way and lawyers are rather expensive. If this was a $50,000 machine it would be a different story but considering sans battery it cost 1/10 that much, it is not cost effective to lawyer up just yet.
www. jungheinrich-lift. com - dealer locator. looks to be 3 dealers to choose from in south carolina.
One sure way to get results from dealer would to be load the thing up and swing by your lawyer and give him a ride to the dealer with you. Explain whats going on and ask for a possible turn around on repair. Let your lawyer take notes and such as this looks to be litigation in the making.
Watched your videos and sounded as though i heard what sounded to be the brake rotor chattering. Possibly the air gap is not correct or disc binding. Also the acceleration rate can be set forks leading and trailing. Being it as a rider platform, the high speed latch could be the problem.
Interesting. I was curious as the techs were trying to convince me that the small steps in acceleration was just they way they are now. In contrast, the Jungheinrich literature describes the situation very differently-
Note the mention of "stepless speed control in below ECR 327 literature" with print date of 2010.
(add www to this) kellytractor.com/eng/images/pdf/forklifts/jungheinrich/walkies/ECR-327-336.pdf
And another brochure from 2010..
madisa.com/sites/default/files/producto/ficha/ficha_jh_carretillaselectricas_ECR327_en_0.pdf
"Controlled by design
Control is the key concept behind the
ECR 327/336. The synchronization of
the Jungheinrich 3-phase AC motor
and controller allows for the smooth,
precise movement of the truck at the
speed you designate"
Smooth, precise movement ?? Mine is the opposite of that !
This situation is most curious. Even if they can't figure out how to fix this particular jack one would think they would get me another or offer a refund, but I continue to be ignored.
I wonder if it's possible all the ECR327's are this way, but all the others perhaps were sold to users that either aren't familiar with how an electric pallet jack is supposed to run and/or to users loading produce or other palletized goods where a bit of crashing into the pallets is no big deal and they are running at such breakneck speed they simply don't care how smooth the acceleration is ?
I drove a BT AC llop today, the throttle control is just as fine / smooth as the older DC version, there are no sudden jumps - just fine smooth progression up & down the throttle range.
By the way your Jungheinrich PPT is behaving, its more like an old fashioned contactor / resistor machine.
